The ESG vendor profile is the market-facing expression of your emissions reporting capability — the section of your capabilities package that tells commercial clients what your ESG program looks like, what data you can provide, and why that makes you a better partner for their reporting obligations. Most restoration contractors don’t have one. The ones who develop it now are filling a space in commercial RFPs that competitors are leaving blank.

What Commercial Clients Are Looking For

Three things: evidence that you understand what they need (familiarity with Scope 3, GHG Protocol, their specific frameworks), evidence that you have a system for producing it (documented methodology, data capture process), and evidence that you have produced it (sample reports, references who can speak to your ESG data delivery). The ESG vendor profile addresses all three.

The Five Components

1. Emissions Reporting Methodology Statement: One paragraph describing your calculation methodology. “We calculate and report per-job greenhouse gas emissions for all commercial restoration engagements using the Restoration Carbon Protocol v1.0, built on GHG Protocol Corporate Value Chain Standard methodology. Our reports cover GHG Protocol Scope 3 Categories 1, 4, 5, and 12. We use EPA and DEFRA emission factors, current as of 2026.”

2. Data Capture Process Description: Brief description of what you track per job, how it’s documented, and what your close-out process looks like. Establishes that your emissions figures are based on actual job data, not after-the-fact estimates. Reference the RCP 12-point data capture standard.

3. Sample Per-Job Carbon Report: A redacted sample from an actual completed job — client name and property address removed, but real numbers. Demonstrates that you’ve actually implemented the system, not just described it. Lets the client’s ESG team evaluate the format before committing to you as a vendor.

4. Delivery Commitment: “We deliver the RCP carbon report within 30 days of job completion for planned maintenance work and within 60 days for emergency loss events.” Gives clients something to put in their contract.

5. Framework Compatibility Statement: “RCP-format reports provide primary Scope 3 data aligned with GHG Protocol methodology, compatible with GRESB Real Estate Assessment, CDP Climate questionnaire, and California SB 253 Scope 3 reporting requirements.”

Where to Use It

Every commercial RFP response, preferred vendor program applications, introductory materials for new commercial client relationships, and your website’s commercial services page. For existing commercial clients, proactively sharing your ESG vendor profile positions you ahead of when they formally request ESG data.

Understanding where restoration contractor data appears in GRESB and CDP disclosures helps contractors frame their value proposition and helps property managers understand what they need from their vendor base. The specific indicators, scoring weight, and data format requirements are all defined — the gap has been the absence of a contractor-side standard for producing the data.

Where Restoration Emissions Appear in GRESB

The GRESB Real Estate Assessment includes GHG Emissions indicators (GHG1–GHG4) and a Supply Chain section covering ESG engagement with contractors. Restoration emissions appear in both.

In the GHG Emissions section, restoration contractor activity contributes to Scope 3 disclosures under Category 1 (purchased services/materials) and Category 5 (waste). GRESB asks whether companies have quantified Scope 3 emissions, which categories are covered, and the data quality (primary vs. estimated). Companies with primary contractor data score higher on the data quality indicator.

In the Supply Chain section, GRESB asks whether the company has engaged with major contractors to understand and reduce emissions. A restoration contractor providing RCP-format per-job carbon reports is supply chain engagement evidence — the property manager can point to those reports as documentation of active contractor engagement on emissions transparency.

Where Restoration Emissions Appear in CDP

CDP’s Climate questionnaire asks companies to report Scope 3 emissions by category with data quality ratings. For commercial real estate companies, restoration contractor emissions sit primarily in Category 1 and Category 5. CDP also asks about supplier engagement on climate change, including whether companies require suppliers to report their emissions.

The Data Format Required

Both GRESB and CDP require: tCO2e by GHG Protocol Scope 3 category, attributable to a specific reporting period, with a methodology description, and evidence of supply chain engagement. An RCP per-job carbon report provides all four elements — the tCO2e figure by category, the reporting period (job dates), the methodology (RCP v1.0, GHG Protocol, EPA/DEFRA factors), and evidence of contractor engagement (the report itself demonstrates communication about emissions).

Aggregating to Portfolio Level

GRESB and CDP require portfolio-level Scope 3 disclosures — totals across all managed properties in the reporting period. The consistent format of RCP reports makes this aggregation straightforward: the same categories appear in every report, allowing simple summation. This is one of the primary reasons standardization matters — if each contractor produces a differently structured report, the ESG team has to reconcile formats before aggregating. RCP eliminates that step.

The Specific GRESB Indicator Where Your Data Lands: GH1

GRESB’s Greenhouse Gas Emissions indicator is designated GH1 in the Real Estate Assessment. It is one of the highest-weighted performance indicators in the entire assessment, alongside EN1 (Energy) and WT1 (Water). The 2025 GRESB Real Estate Scoring Document confirms that GH1 is scored using a relative methodology — meaning an entity’s score is determined not just by its standalone performance but by how it compares against benchmark groups of comparable properties by type and geography.

Understanding GH1 is essential for contractors because it is the specific field in the GRESB Assessment Portal where your client’s ESG team enters the emissions data you provide. The more complete and primary-data-quality your RCP records are, the higher your client’s GH1 data coverage score — which in 2025 became a newly scored metric in the assessment.

What GH1 Requires

GH1 assesses the entity’s measurement of GHG emissions across Scope 1, 2, and 3. The 2025 updates specifically require:

• Scope 2: Location-based reporting is mandatory and scored. Market-based is optional and does not affect the score.
• Scope 3: Participants must identify and report material Scope 3 emission categories. Restoration contractor emissions land in Category 1 (purchased goods and services) and Category 4 (upstream transportation) of the client’s Scope 3 inventory.
• Data coverage: A newly scored metric in 2025. GH1 now explicitly scores data coverage — the percentage of the portfolio’s floor area for which verified GHG data is reported. Higher coverage = higher score. RCP records that cover more of a client’s restoration events improve their data coverage metric.
• Third-party review: Also newly scored in 2025. For entities of sufficient size (per indicator RC7), third-party assurance of GHG emissions data is now a scoring factor. This is the long-term trajectory toward verifiable contractor data.

The 2026 Scope Reclassification

GRESB has announced a significant methodology change for 2026: Tenant Spaces–Landlord Controlled emissions, which were previously classified as Scope 3, will be reclassified as Scope 1 and 2. This affects how landlord-controlled tenant space energy is categorized. It does not affect restoration contractor emissions, which remain Scope 3 Category 1 and 4 for the property owner. But it means your clients’ ESG teams are actively restructuring their Scope 3 inventory in 2026 — which is an ideal moment to be the vendor that provides clean, structured Scope 3 data that reduces their workload.

GRESB Assessment Submission Deadline

The GRESB Real Estate Assessment submission window is April–July each year. The 2026 assessment covers calendar year 2025 performance data. Contractors should deliver annual RCP Portfolio Summaries to GRESB-reporting clients by May at the latest to allow time for data entry before the July deadline.

CDP Supply Chain: Where Your Data Appears and What Format It Needs

CDP operates a Supply Chain program through which member companies — many of them institutional property owners, REITs, and commercial facility operators — request annual emissions data from their suppliers via a standardized questionnaire. If a commercial property manager client is a CDP Supply Chain member, they will send you a questionnaire link at some point. Understanding the questionnaire structure helps you respond efficiently using RCP data.

CDP Supply Chain Questionnaire Structure

The CDP Supply Chain questionnaire asks suppliers to disclose:

• Scope 1, 2, and 3 GHG emissions for the most recent reporting year
• Whether you have set science-based emissions reduction targets
• Whether you have board-level oversight of climate risks
• Your approach to climate risk management and opportunity identification
• Whether you engage your own supply chain on emissions reduction

For restoration contractors, the relevant sections are Scope 1, 2, and 3 disclosure. Scope 1 covers your company’s direct emissions (your offices, equipment you own). Scope 2 covers your purchased electricity for operations. Scope 3 covers upstream and downstream emissions in your value chain — which, for restoration contractors, includes the materials you purchase, the waste you generate, and eventually the client-facing emissions tracked by RCP.

RCP Job Carbon Reports aggregate into a portfolio Scope 3 figure that the contractor can disclose as their Category 11 (use of sold products, if applicable) or as context for their supplier’s Category 1 emissions. The key data point CDP needs is a total annual Scope 3 figure with methodology disclosure. Your RCP Portfolio Summary (all per-job records summed for the year) provides this directly.

ESG Data Management Platforms That Accept RCP Data

Commercial property managers rarely enter vendor data manually into GRESB or CDP. They use ESG data management platforms that aggregate across their vendor base and generate GRESB/CDP-ready submissions. The leading platforms in commercial real estate:

• Measurabl: Used by major REITs and institutional property managers. Accepts structured CSV and API data inputs. A Measurabl-compatible RCP CSV uses columns: property_id, vendor_name, reporting_period, scope3_category, emissions_tco2e, calculation_method, data_quality.
• Yardi Elevate: Yardi’s ESG module integrated with its property management suite. Accepts vendor emissions data via CSV import aligned with GHG Protocol category structure.
• Deepki: European-headquartered, used by CSRD-obligated property companies with US assets. Accepts API integrations for Scope 3 supplier data.
• Atrius (formerly BuildingIQ): Uses CBECS data for estimation where supplier data is unavailable. Accepts actual supplier data uploads that override estimates — which is why delivering RCP data matters even if the client has an ESG platform that estimates your contribution.

The RCP-JCR-1.0 JSON schema is designed to be translatable to any of these platform formats. The emissions_summary object maps directly to GHG Protocol category totals. The data_quality section maps to the methodology disclosure fields all four platforms require.

---

Having the data is not enough. The way you package and deliver per-job carbon data determines whether your commercial clients can use it or whether it becomes a research project for their ESG team. Usable data arrives in the right format, at the right time, with enough context to slot directly into their Scope 3 inventory without additional processing.

What Commercial Clients Actually Need

A commercial property manager’s ESG team needs: emissions in metric tons of CO2 equivalent (tCO2e), broken down by GHG Protocol Scope 3 category, attributed to a specific property and time period, with a methodology citation they can use in their disclosure documentation. Everything else is secondary. Lead with the numbers in the right format.

The RCP Per-Job Carbon Report Format

The RCP per-job carbon report is a single-page document containing: job identification (contractor, job ID, property address, job type, dates), emissions summary (total tCO2e with subtotals by Scope 3 category), category breakdown with activity data and emission factors, methodology citation (“Restoration Carbon Protocol v1.0, GHG Protocol Corporate Value Chain Standard, EPA/DEFRA emission factors”), and data quality notation flagging any estimated data points.

Delivery Timing and Format

Deliver within 30 days of job completion for planned maintenance work, 60 days for emergency loss events. Delivery timing matters because commercial clients aggregate Scope 3 data on an annual cycle — reports received after their cut-off date get pushed to the following year’s inventory.

Format options in order of preference: structured data file (CSV or JSON) feeding directly into ESG software, PDF carbon report for manual entry, standardized email summary with required fields clearly labeled. Ask which format the client’s ESG team prefers.

Building the Report Into Job Close-Out

Treat the per-job carbon report as a standard job deliverable — same category as moisture readings or job completion certificate. Adding it to your close-out checklist as a required item for commercial jobs ensures consistent delivery and builds the data discipline needed for reliable ESG reporting.

Handling Historical Data Requests

Commercial clients building their first Scope 3 inventory often request historical data going back two or three years. For jobs completed before RCP implementation, produce a retrospective estimate using RCP methodology applied to available historical records. Flag as estimated with documentation of what records were used. A documented estimate is more useful than a refusal to provide historical data.

---

Delivery Formats by Client Type

The format your client needs depends entirely on how their ESG team processes vendor data. Three delivery formats cover the full spectrum:

Format 1: PDF Job Carbon Report (Manual Entry Clients)

For clients whose ESG coordinator manually enters data into GRESB, CDP, or their ESG platform, the PDF Job Carbon Report is sufficient. It should be delivered at job close-out and retained in the job file. The ESG coordinator will manually transfer the total tCO₂e figure and category breakdown into their platform at the annual reporting cycle. Deliver via email to the property’s sustainability contact (not the facilities manager — find the right person).

Format 2: RCP JSON Record (Platform-Integrated Clients)

For clients using Measurabl, Yardi Elevate, Deepki, or Atrius, provide the machine-readable RCP-JCR-1.0 JSON record. These platforms accept structured data uploads or API POST requests. Coordinate with the client’s ESG platform administrator to establish the intake endpoint. Once configured, RCP records can be transmitted automatically at job close-out without human intervention on either side.

Format 3: Annual RCP Portfolio Summary CSV (GRESB/CDP Reporters)

For clients submitting GRESB or CDP, the most useful annual deliverable is a portfolio summary CSV that aggregates all per-job records for their properties during the reporting year. The recommended column structure:

property_id | property_address | job_id | job_type | job_start | job_end | total_tco2e | cat1_tco2e | cat4_tco2e | cat5_tco2e | cat12_tco2e | calculation_method | data_quality_notes

This CSV maps directly to the Scope 3 supplier data intake format accepted by Measurabl and Yardi Elevate. Deliver it in January or February for calendar-year reporters so their ESG team has time to validate before the April–July GRESB window.

Measurabl-Ready CSV Field Mapping

RCP Field	Measurabl Column	Notes
job_identification.client_name	entity_name	Must match the client’s Measurabl entity name exactly
property_address	asset_id or asset_address	Use client’s Measurabl asset ID if known
job_start_date / job_completion_date	reporting_period_start / end	ISO 8601 date format required
emissions_summary.category_1_materials_tco2e	scope3_cat1_mt_co2e	Metric tons CO₂e
emissions_summary.category_4_transportation_tco2e	scope3_cat4_mt_co2e	Metric tons CO₂e
emissions_summary.total_job_emissions_tco2e	scope3_total_mt_co2e	Sum of all categories
data_quality.calculation_method flags	data_quality_notes	Flag proxy vs. primary data points

Timing: When to Deliver and When Clients Need It

The most common contractor failure is not the data format — it is the timing. Most restoration contractors wait for clients to ask. By then, the client’s ESG submission deadline is two weeks away and their team is scrambling to collect data from a dozen vendors simultaneously. Be the contractor who delivers without being asked.

The RCP delivery calendar:

• At job close-out (ongoing): Deliver the per-job RCP Job Carbon Report within 30 days of completion. Don’t wait for year-end.
• January 31: Deliver the annual RCP Portfolio Summary for all calendar-year reporters. Covers the prior year’s jobs by property.
• March 31: Final deadline for any corrections or updates to the prior year’s records before GRESB data lock.
• April–July: GRESB submission window. Your data should already be in the client’s ESG platform. No action required from you during this period if delivery was on time.

Asbestos and hazmat abatement generates the highest emissions per unit of material removed of any restoration job type. The combination of specialized transportation to licensed disposal facilities, extreme PPE consumption, and high-emissions disposal methods (including incineration for some regulated materials) produces an emissions profile that is fundamentally different from standard C&D work. This guide provides the emission factors, calculation methodology, and a worked example for a commercial ACM abatement project.

Regulated Materials: Classification Before Calculating

Regulated Material	Common Location in Commercial Buildings	Disposal Classification	Emission Factor Premium vs. Standard C&D
Asbestos-containing materials (ACM) — friable	Pipe insulation, ceiling tiles (older), spray fireproofing	Licensed hazmat landfill	2.4× standard C&D
ACM — non-friable	Floor tiles, roofing materials, joint compound	Licensed C&D landfill with ACM cell	1.8× standard C&D
Lead-based paint debris	Pre-1978 painted surfaces — all types	Licensed hazmat landfill or TCLP-based classification	2.2× standard C&D
PCB-containing materials	Caulk (pre-1978), fluorescent light ballasts, transformers	Licensed hazmat incineration (50 ppm+ PCB)	11.6× standard C&D (incineration)
Mercury-containing equipment	Fluorescent lamps, thermostats, switches	Mercury recycler or licensed hazmat	1.5× standard C&D + recycling credit

Category 4: Transportation Emission Factors

Hazmat abatement transportation has two components with fundamentally different emission profiles: crew and equipment mobilization (standard restoration factors) and regulated waste transportation (elevated factors due to distance to licensed facilities and loaded vehicle weight).

Vehicle Type	kg CO2e per mile	Use
Crew vehicles (light truck, van)	0.503	Daily crew transport
Decontamination unit (trailer-mounted)	1.084	Mobilization and demobilization
Negative air pressure / HEPA equipment trailer	1.084	Equipment mobilization
Licensed hazmat waste hauler (ACM, lead)	3.20	Regulated C&D to licensed landfill — loaded
Licensed hazmat waste hauler (PCB, mercury)	3.80	High-hazard regulated waste — specialty vehicle

Licensed disposal facility distance note: Licensed hazmat landfills capable of receiving friable ACM are significantly less common than standard C&D landfills. Average transport distance to a licensed ACM facility is 45–90 miles in most US metro areas, compared to 10–25 miles for standard C&D. Use actual haul distances from your waste manifests. If unavailable, use 60 miles as the default for ACM waste and 80 miles for PCB/high-hazard waste.

Category 1: Materials Emission Factors

Material	Unit	kg CO2e per unit	Notes
Level C PPE kit (Tyvek, gloves, boot covers, goggles)	Kit per entry	1.8	Full replacement required each decon exit
Level B PPE (supplied air + full encapsulating suit)	Kit per entry	4.2	Higher-grade suit + air supply equipment
Half-face respirator, P100 + OV cartridges (pair)	Pair	0.8	EPA EEIO — medical equipment
Full-face respirator cartridges (pair)	Pair	1.2	EPA EEIO — medical equipment
HEPA filter (negative air machine)	Each	3.2	EPA EEIO — industrial machinery
Wetting agent / amended water (surfactant)	Liter	1.4	EPA EEIO — chemical manufacturing (applied during ACM removal to suppress fibers)
6-mil poly sheeting (containment, double-layer required)	m²	1.10	Double-layer = 2× standard poly factor
Glove bags (for pipe insulation removal)	Each	0.85	EPA EEIO — plastics product manufacturing
Negative air pressure machine HEPA filters	Each	3.2	Changed more frequently under hazmat conditions — typically every 8–12 hours
Disposal bags (6-mil, ACM-labeled)	Each (33 gallon)	0.55	EPA EEIO — plastics manufacturing

PPE consumption rate for hazmat abatement: Unlike standard restoration where PPE may last a full shift, hazmat abatement requires full PPE replacement each time a worker exits the work area through the decontamination unit. A standard 8-hour ACM abatement shift with 3 exits per worker produces 3 complete PPE kit replacements per worker. For crew of 4: 4 workers × 3 exits × 1.8 kg/kit = 21.6 kg CO2e in PPE alone per day.

Category 5: Waste Emission Factors

Waste Type	Disposal Method	tCO2e per ton	Source
Friable ACM (pipe insulation, fireproofing)	Licensed hazmat landfill	0.42	EPA WARM + licensed facility transport premium
Non-friable ACM (floor tiles, roofing)	Licensed C&D landfill, ACM cell	0.28	EPA WARM + regulated C&D transport
Lead paint debris (TCLP-classified hazardous)	Licensed hazmat landfill	0.38	EPA WARM + hazmat transport
PCB-containing materials ≥50 ppm	Licensed PCB incineration	1.85	EPA hazardous waste incineration emission factors
PCB-containing materials <50 ppm (non-hazardous PCB)	Licensed landfill	0.22	EPA WARM + transport premium
Mercury-containing lamps	Mercury recycler	0.15	EPA WARM — recycling credit partially offsets
Mercury-containing thermostats/switches	Mercury recycler	0.12	Similar to lamps
Decontamination wastewater	Municipal wastewater (if non-hazardous) or permitted facility	0.000272 per liter	EPA WARM — wastewater treatment
Spent PPE (hazmat grade)	Licensed hazmat landfill	0.30	Higher than standard PPE due to contamination classification

Complete Worked Example: Pre-1970 Commercial Office Building, Floor Tile and Ceiling Tile ACM Abatement

Job profile: 5,000 sq ft floor tile removal (non-friable ACM, 9″ floor tiles) and 5,000 sq ft suspended ceiling tile replacement (non-friable ACM) in a 1967 office building being renovated. No pipe insulation abatement in scope. Crew: 4 abatement technicians, 8-day project. Air monitoring by third-party IH (not in contractor scope). Facility: 28 miles from job site. Licensed C&D landfill with ACM cell: 54 miles from job site.

Category 4 — Transportation

Crew vehicles: 2 light trucks × 56 mi RT × 9 trips (8 work days + equipment pickup) = 504 mi × 0.503 = 254 kg CO2e

Decontamination unit (trailer): 1 × 56 mi × 2 trips = 112 mi × 1.084 = 121 kg CO2e

Negative air / HEPA equipment trailer: 1 × 56 mi × 2 trips = 112 mi × 1.084 = 121 kg CO2e

ACM waste haul (non-friable floor + ceiling tiles, 2 loads): 2 × 108 mi RT to licensed facility × 3.20 kg/mi = 691 kg CO2e

Category 4 total: 1,187 kg CO2e = 1.19 tCO2e

Category 1 — Materials

PPE (Level C, 4 workers × 8 days × 3 exits/day = 96 kit replacements): 96 × 1.8 kg = 173 kg CO2e

P100 respirator cartridges: 4 workers × 8 days × 1 replacement/day = 32 pairs × 0.8 = 26 kg CO2e

6-mil poly sheeting (double-layer containment, 500 sq ft decon area + staging): 200 m² × 1.10 kg/m² = 220 kg CO2e

HEPA filters (4 negative air machines × 2 changes/day × 8 days = 64 filters): 64 × 3.2 = 205 kg CO2e

Wetting agent for tile removal (applied to floor tiles before removal): 5,000 sq ft × 0.003 L/sq ft = 15 liters × 1.4 = 21 kg CO2e

ACM disposal bags (33-gallon, for ceiling tile bagging): estimated 80 bags × 0.55 = 44 kg CO2e

Category 1 total: 689 kg CO2e = 0.69 tCO2e

Category 5 — Waste

Floor tiles (non-friable ACM, 5,000 sq ft × 4 lbs/sq ft = 10 tons): 10 × 0.28 = 2.80 tCO2e

Ceiling tiles (non-friable ACM, 5,000 sq ft × 1.5 lbs/sq ft = 3.75 tons): 3.75 × 0.28 = 1.05 tCO2e

Spent PPE (hazmat-grade, 96 kit replacements + misc): estimated 0.8 tons × 0.30 = 0.24 tCO2e

Decontamination wastewater (~800 liters over 8 days): 800 × 0.000272 = 0.22 kg CO2e (negligible)

Category 5 total: 4.09 tCO2e

Category 12 — Demolished Hazardous Building Materials

For ACM floor and ceiling tiles, the material itself is the hazardous waste — it flows to Category 5 disposal accounting. Category 12 is not separately calculated for ACM materials that are classified as hazardous waste upon removal, since the disposal emissions are already captured in Category 5. This is a key distinction from standard demolition: ACM materials do not generate both Category 5 and Category 12 emissions — they generate Category 5 only.

Category 12 total: 0 tCO2e (ACM materials classified as regulated waste at removal — captured in Category 5)

Job Total

Category	tCO2e	% of Total
Category 4 — Transportation	1.19	20%
Category 1 — Materials	0.69	12%
Category 5 — Waste disposal (regulated)	4.09	68%
Category 12 — Demolished materials	0.00	0%
Total	5.97 tCO2e	100%

Key observation: For hazmat abatement, Category 5 waste disposal is the dominant emission source at 68% of total — confirming that reduction strategies for this job type should focus on waste minimization (reducing the volume of regulated material requiring licensed disposal) rather than fleet or materials optimization. In practice, this means accurate pre-abatement survey to confirm material quantities precisely, minimizing unnecessary demolition scope, and pursuing licensed recycling options for non-friable ACM where available.

Asbestos-Containing Materials in Landfill: Zero Methane — A Critical Correction

The emission factors for ACM disposal in the Category 5 table include a transport premium over EPA WARM but implicitly apply WARM’s underlying methane generation assumptions. For asbestos-containing materials, this is incorrect. Asbestos is a mineral silicate — it is inorganic and will not biodegrade in a landfill under any conditions. ACM disposal generates zero landfill methane.

The applicable emission factors for ACM disposal are therefore limited to:

• Transportation to the licensed facility (Category 4, already calculated separately)
• Landfill equipment operation at the disposal site (negligible, accounted for in WARM’s non-biodegradable material factors)

The corrected disposal emission factors for ACM, based on inert material treatment rather than C&D composite factors:

ACM Type	Previous factor	Corrected factor	Basis
Friable ACM (pipe insulation, fireproofing)	0.42 tCO₂e/ton	~0.018 tCO₂e/ton	Transport + inert landfill equipment only (no methane)
Non-friable ACM (floor tile, roofing)	0.28 tCO₂e/ton	~0.018 tCO₂e/ton	Transport + inert landfill equipment only (no methane)

The transport factor of ~0.018 tCO₂e/ton is derived from EPA’s assumed 1.8 gallons diesel per short ton for C&D haul transport (10.21 kg CO₂e/gallon × 1.8 = 18.4 kg CO₂ = 0.018 tCO₂e/ton). Actual transport emissions should be calculated from documented haul distances. The significantly lower disposal factor reflects the correct classification of asbestos as an inert material rather than a decomposable C&D composite.

NESHAP thresholds for regulatory reference: EPA NESHAP (40 CFR 61.145) requires notification when a demolition or renovation project disturbs 160 square feet, 260 linear feet, or 35 cubic feet of Regulated Asbestos-Containing Material (RACM). Below these thresholds, disposal may proceed without NESHAP notification. ACM waste carries DOT Class 9 designation, UN ID #2212, regardless of quantity.

Lead-Based Paint Waste: Residential RCRA Exemption Clarified

The Category 5 table applies a uniform hazardous waste disposal factor for lead paint debris. This overstates emissions for the most common lead abatement scenario in restoration work.

Residential lead-based paint waste is exempt from RCRA hazardous waste classification regardless of lead concentration, under the RCRA household waste exemption (42 U.S.C. §6901; EPA Final Rule, 68 FR 36487, June 18, 2003). This applies to all renovation, repair, and painting work in residential structures, including investment properties and apartments. Lead paint chips, dust, and blasting waste from residential work go to standard C&D or MSW landfills at standard disposal emission factors — not licensed hazardous waste facilities.

Non-residential lead abatement requires TCLP testing. The RCRA hazardous waste threshold for lead is 5.0 mg/L (D008 waste code). Paint chips and blasting waste from commercial structures frequently exceed this threshold and require licensed hazardous waste disposal at approximately 250–600 kg fossil CO₂ per tonne (Zero Waste Europe, hazardous waste incineration range). Whole-building demolition debris with LBP attached to substrates may pass TCLP if lead is diluted in the substrate mass.

Corrected lead waste emission factors by context:

Context	RCRA Classification	Disposal Method	tCO₂e per ton
Residential LBP abatement (any concentration)	RCRA-exempt	Standard C&D landfill	0.16 (WARM v16 C&D)
Non-residential LBP, TCLP <5.0 mg/L	Non-hazardous	Standard C&D landfill	0.16 (WARM v16 C&D)
Non-residential LBP, TCLP ≥5.0 mg/L	D008 hazardous	Licensed hazmat disposal	0.28–0.55 (incineration range)

---

Decontamination Shower Water: Quantified

OSHA 29 CFR 1926.1101(j) mandates a three-stage decontamination unit (Equipment Room → Shower Room → Clean Room) for all regulated asbestos abatement work. Decontamination shower water represents a measurable but typically minor wastewater emission source.

At standard shower flow rates of 2.0–2.5 GPM with 3–5 minute showers, each decontamination cycle consumes approximately 7.5–12.5 gallons per worker per cycle. Workers shower at lunch and end-of-shift, producing 15–25 gallons per worker per day. A 4-person crew over a 5-day project generates approximately 300–500 gallons of decontamination shower water.

Decon water from non-hazardous LBP projects discharges to municipal sewer after filtration through ≥5.0 micron filtration (required in NY, PA, CT). At the wastewater treatment energy factor of 0.00074 kg CO₂e per gallon, 400 gallons of decon water produces approximately 0.30 kg CO₂e — negligible in the context of total job emissions but documented here for methodological completeness. For PCB or mercury decontamination water, specialized treatment or drumming for permitted disposal may be required.

---

PPE Weight and Consumption Data: Corrected

The Category 1 table uses kit-level EPA EEIO estimates for PPE. More precise data is now available for the primary components.

DuPont Tyvek 400 coveralls (the standard for asbestos and lead abatement work) weigh approximately 180 grams per suit (HDPE flash-spun fabric at 1.2 oz/sq-yd). Workers typically use two suits per day during active abatement — one changed at lunch, one at end-of-shift. A 4-person crew over a 5-day project consumes 40–80 Tyvek suits (7.2–14.4 kg of HDPE). At an HDPE production factor of 1.8–3.5 kg CO₂e/kg, coveralls alone contribute 13–50 kg CO₂e per project. This is substantially lower than the EPA EEIO apparel manufacturing proxy of 1.2 kg CO₂e per suit implied by the current table.

Nitrile gloves: 0.0277 kg CO₂e per glove (Top Glove 2024 SATRA-verified LCA). Per pair: 0.055 kg CO₂e. This is lower than the 0.3 kg CO₂e/pair EPA EEIO proxy by approximately 82%.

N95 respirators: 0.05 kg CO₂e per unit (Springer Environmental Chemistry Letters, 2022). This is lower than the EPA EEIO medical equipment proxy values in current use.

Use these LCA-sourced per-unit values in place of the EPA EEIO kit factors for contractors seeking to maximize data quality for SBTi-committed or CSRD-exposed clients.

Mold remediation has a different emissions signature than water damage or fire restoration — it is slower, more materials-intensive per square foot, and dominated by chemical treatments and containment infrastructure rather than vehicle transportation. This guide provides the emission factors, calculation methodology, and a complete worked example for a Condition 3 commercial mold remediation.

Job Classification Before Calculating

Condition (IICRC S520)	Scope	Emissions Profile	Typical Range
Condition 1 — Normal fungal ecology	No remediation	N/A	0 tCO2e
Condition 2 — Settled spores, no active growth	HEPA vacuum + antimicrobial wipe-down	Transportation dominant, minimal materials	0.1–0.4 tCO2e

Condition 3 — Large commercial HVAC system affected	Full remediation + duct cleaning/replacement	All four categories significant	2.0–8.0 tCO2e

Category 4: Transportation Emission Factors

Mold remediation typically involves more crew trips relative to equipment trips than fire or water jobs — the slower pace means daily crew mobilization across an extended project without proportionally heavy equipment deployment.

Vehicle Type	kg CO2e per mile	Typical Use
Light truck / work van	0.503	Daily crew transport
Cargo van (containment materials)	0.503	Poly sheeting, negative air machines
Medium equipment trailer	1.084	Air scrubbers, negative air pressure units
Dump truck (debris)	2.25 (loaded) / 1.612 (empty)	Demolition debris removal

Category 1: Materials Emission Factors

Mold remediation is the most materials-intensive restoration job type per square foot of affected area. Containment infrastructure, biocidal treatments, and HEPA filtration media represent significant Category 1 emissions even on smaller jobs.

Biocide application rate proxies by condition and surface type: Condition 3 porous surfaces (drywall, wood framing) — 0.020 liters/sq ft for first application, 0.015 liters/sq ft for second application. Non-porous surfaces — 0.008 liters/sq ft. HVAC duct interiors — 0.012 liters/linear ft.

Containment materials proxy: Standard containment setup for a single affected room uses approximately 50 linear feet of 6-mil poly at ceiling height (8 ft average) = 120 m² of sheeting. Add 20 m² per additional doorway or penetration. Reusable zipper doors amortize over approximately 20 uses before replacement.

Complete Worked Example: Condition 3 Commercial Mold — Server Room and Adjacent Office

Job profile: HVAC condensate leak caused active mold growth behind drywall in a server room (200 sq ft) and adjacent office (300 sq ft). Total affected area: 500 sq ft. Scope: containment setup, demolition of all affected drywall (both rooms) and insulation (server room only), biocide treatment, HEPA vacuuming, clearance prep. No HVAC duct work in scope. Duration: 5 days. Crew: 2 technicians. Facility: 19 miles from job site.

Category 4 — Transportation

Crew van: 1 cargo van × 38 mi RT × 6 trips (5 work days + equipment pickup) = 228 mi × 0.503 = 115 kg CO2e

Equipment delivery (negative air machines): 1 × 38 mi × 2 trips = 76 mi × 1.084 = 82 kg CO2e

Debris removal (one load, dump truck): 1 × 22 mi × 2.25 = 50 kg CO2e

Category 4 total: 247 kg CO2e = 0.25 tCO2e

Category 1 — Materials

Biocide (first application — 500 sq ft porous surfaces): 500 × 0.020 = 10 L × 2.8 = 28 kg CO2e

Biocide (second application): 500 × 0.015 = 7.5 L × 2.8 = 21 kg CO2e

Encapsulant (server room only, non-porous surfaces): 2 gallons × 4.2 = 8 kg CO2e

6-mil poly sheeting: 2 rooms × 120 m² each = 240 m² × 0.55 = 132 kg CO2e

Zipper doors (2 rooms × 2 doors, reusable at 20-use amortization): 4 × 1.8/20 = 0.4 kg CO2e (negligible)

HEPA filters (2 negative air machines × 2 filter changes): 4 × 3.2 = 13 kg CO2e

HEPA vacuum bags: 10 bags × 0.4 = 4 kg CO2e

PPE: 2 tech × 5 days × 2 Tyvek = 20 × 1.2 = 24 kg; gloves: 2 × 5 × 4 = 40 pairs × 0.3 = 12 kg; respirator cartridges: 2 × 5 × 1 pair = 10 × 0.8 = 8 kg. PPE: 44 kg CO2e

Category 1 total: 250 kg CO2e = 0.25 tCO2e

Category 5 — Waste

Mold-contaminated drywall (500 sq ft × 2.5 lbs/sq ft = 1,250 lbs = 0.57 tons): 0.57 × 0.18 = 0.10 tCO2e

Server room insulation (200 sq ft × 1.5 lbs/sq ft = 300 lbs = 0.14 tons): 0.14 × 0.33 = 0.05 tCO2e

Spent HEPA filters (4 filters × 2 lbs each = 8 lbs = 0.004 tons): 0.004 × 0.28 = 0.001 tCO2e (negligible)

PPE and containment disposal (~0.06 tons): 0.06 × 0.25 = 0.015 tCO2e

Category 5 total: 0.17 tCO2e

Category 12 — Demolished Materials

Drywall demolished (500 sq ft): 0.57 tons × 0.16 = 0.09 tCO2e

Fiberglass insulation (server room, 200 sq ft): 0.14 tons × 0.33 = 0.05 tCO2e

Category 12 total: 0.14 tCO2e

Job Total

Category	tCO2e
Category 4 — Transportation	0.25
Category 1 — Materials	0.25
Category 5 — Waste disposal	0.17
Category 12 — Demolished materials	0.14
Total	0.81 tCO2e

Key observation from this example: Category 1 (materials) and Category 4 (transportation) are nearly equal at 0.25 tCO2e each — confirming that mold remediation has a more balanced emissions profile than water or fire jobs where transportation typically dominates. This means reduction strategies that focus on materials (lower-emission biocide formulations, reusable containment systems) have comparable impact to fleet electrification for this job type.

Negative Air Machine Energy Consumption: Model-Specific Data

The Category 1 table above uses a single HEPA filter factor and generic equipment values. Negative air machines (NAMs) are the dominant energy consumer in mold containment and their wattage varies dramatically across models at similar CFM ratings. Use model-specific data where available; use the weighted average proxy where it is not.

Model	CFM	Amps (high speed)	Approx. watts	kWh per 24-hr day
Aramsco Syclone (1000 CFM)	1,000	15A	~1,725W	41.4
Nikro NCF1800 (2-speed)	1,800	9A	~1,035W	24.8
Abatement Technologies FA2000EC	1,975	20A	~2,300W	55.2
Aerospace 2000 (Novatek)	2,000	9.4A	~1,034W	24.8
IDS Blast F2100 (2000 CFM)	2,000	20A	~2,300W	55.2

RCP proxy for NAMs where model is unspecified: 1,500W / 36 kWh per 24-hour day (weighted average across the above models). At the national grid emission factor (0.3499 kg CO₂e/kWh), a single NAM running 24 hours generates approximately 12.6 kg CO₂e per day. A large commercial remediation running four NAMs continuously for 10 days produces roughly 504 kg CO₂e from containment energy alone — a meaningful emission source that should be documented in equipment runtime records rather than left as a proxy.

HEPA filter note: HEPA filters in NAMs are single-use and non-cleanable. Manufacturer recommendations call for replacement when differential pressure exceeds 2.6 inches W.C. on high speed (Nikro NCF1800 spec) or approximately every 6–12 months under normal use. During active mold remediation with high spore loads, replacement frequency increases. Standard HEPA filter dimensions for 2,000 CFM machines are 16″ × 24″ × 11.5″. Log filter changes at the job level for accurate Category 1 accounting.

Mold-Contaminated Debris: Waste Classification Confirmed

Mold waste is not regulated at any level — federal or state — regardless of IICRC S520 contamination condition. The University of Florida Environmental Health and Safety states plainly: mold-contaminated material is not regulated and can be disposed of as regular waste. Condition 3 materials (actively colonized porous materials) must be physically removed and double-bagged in sealed 6-mil polyethylene per IICRC S520 protocol, but disposal occurs in standard MSW or C&D landfills without special permitting or manifest requirements.

Florida, Texas, New York, and California all lack special disposal requirements for mold-remediation waste. The sole exception applies when mold co-occurs with regulated materials: if Condition 3 remediation uncovers asbestos or lead, those materials are governed by their own regulatory frameworks and require separate handling and disposal.

The Scope 3 implication: Standard EPA WARM v16 landfill emission factors apply to all mold remediation debris. There is no regulatory category requiring hazardous waste incineration, permitted treatment facilities, or elevated disposal factors for mold waste. Do not apply contamination premiums to mold waste disposal emission calculations.

Desiccant vs. Refrigerant Dehumidifier: Corrected Energy Factor

The Category 1 table does not distinguish between refrigerant-based (compressor) and desiccant dehumidifiers. For mold remediation in cold environments — unheated crawl spaces, winter deployments, structures with disrupted HVAC — desiccant units are the only viable option below approximately 50°F (10°C). Their energy consumption per pint of moisture removed is substantially higher than the refrigerant default.

Technology	Energy efficiency	Operating range	RCP factor (kWh/pint)
Refrigerant (LGR compressor)	~1.8 L/kWh (ENERGY STAR IEF)	Above ~50°F / 10°C	0.22–0.35
Desiccant (silica gel + PTC heater)	~0.5–0.8 L/kWh	Down to -4°F / -20°C	0.50–0.80

For any mold job where desiccant dehumidifiers are deployed, use the 0.50–0.80 kWh/pint range rather than the standard refrigerant factor. Document dehumidifier type in job equipment records. The difference is not trivial: a desiccant unit running at 0.65 kWh/pint generates approximately 2–3× the equipment energy emissions of an equivalent-capacity LGR unit on the same job.

Antifungal Treatment Emission Factors: Updated and Corrected

Borax-Based Treatments

Borax (sodium tetraborate) has published lifecycle assessment data from a peer-reviewed MDPI Sustainability study (2022, 14(3), 1787): borax anhydrous carries a GWP of approximately 495 kg CO₂e per functional unit, with steam during refinement contributing 46% of the total impact. The per-kg figure requires verification against the study’s functional unit declaration, but the borax production process is energy-intensive relative to its inorganic simplicity, driven by mining, drying, and purification operations. The EPA EEIO inorganic chemical proxy of 1.1 kg CO₂e/kg currently in the table is a reasonable approximation pending manufacturer-specific EPD data. Flag as estimated.

Tea Tree Oil and Botanical Treatments

Tea tree oil (Melaleuca alternifolia) carries no published lifecycle emission factor as of April 2026. Essential oil production is energy-intensive: steam distillation yields are approximately 1–2% of raw plant material by weight, meaning roughly 50–100 kg of plant material is processed per kg of oil extracted. Combined with agricultural inputs, transport, and distillation, the production footprint is estimated at 15–50 kg CO₂e per kg of tea tree oil — substantially higher per kg than synthetic biocides, though applied in much smaller quantities. The RCP treats tea tree oil treatments as a data gap. Apply the EPA EEIO chemical manufacturing proxy (2.8 kg CO₂e/liter of diluted product) and flag as estimated pending manufacturer disclosure.

Copper-Based Fungicides

Copper production averages approximately 2.6 tonnes CO₂e per tonne of copper (peer-reviewed industry average). Copper sulfate processing adds further energy overhead. Estimated emission factor for copper sulfate fungicide treatments: 3–5 kg CO₂e/kg. Apply where copper-based treatments are used and flag as estimated. No EPA-specific factor exists for copper sulfate in the WARM or EF Hub databases.

Fire and smoke restoration generates the most variable Scope 3 emissions of any restoration job type. A contained single-room smoke job and a multi-floor structural fire with hazmat abatement and full reconstruction can both appear on your P&L as “fire restoration” — but their emissions differ by a factor of 20 or more. This guide gives you the emission factors, the calculation methodology, and a complete worked example to produce an accurate per-job figure regardless of where on that spectrum your job falls.

Job Classification: Phase and Scope

Before calculating, identify which phases are in your scope of work and document them separately. Emissions from mitigation and reconstruction phases should be tracked separately even if invoiced together — they may occur in different reporting years.

Phase	Dominant Emission Categories	Typical Range
Mitigation only (no structural demolition)	Cat 4 transportation, Cat 1 materials, Cat 5 debris	1.0–6.0 tCO2e
Mitigation + selective demolition (1 room/suite)	All four categories, Cat 12 significant	3.0–12.0 tCO2e
Large-scale fire + ACM abatement + reconstruction	All four categories, Cat 5 hazmat dominant	15.0–100+ tCO2e

Category 4: Transportation Emission Factors

Fire restoration deploys more vehicle types per job than any other restoration category. Account for each separately.

Vehicle Type	kg CO2e per mile	Common Use in Fire Restoration
Light truck / work van	0.503	Crew transportation, initial response
Medium equipment trailer	1.084	Air scrubbers, ozone generators, thermal foggers
Box truck / pack-out truck	1.084	Content pack-out and storage transport
Heavy dump truck (unloaded)	1.612	Debris removal mobilization
Heavy dump truck (loaded)	2.25	Debris removal trips to landfill/transfer
Specialty hazmat transport (ACM)	2.80	Asbestos or lead waste to permitted facility

Content pack-out note: Pack-out is frequently the second-largest transportation source on large fire jobs. Track pack-out truck trips separately from crew mobilization and debris removal trips. Pack-out involves loaded trucks going to storage and returning empty — apply loaded emission factor for outbound, unloaded for return.

Category 1: Materials Emission Factors

Material	Unit	kg CO2e per unit	Notes
Chemical sponge (dry soot sponge)	Each	0.15	EPA EEIO — cleaning products
Dry ice (CO2 pellets for blasting)	kg	0.85	Industrial CO2 production — use with caution; CO2 is released on use, but EPA factors cover production
Hydroxyl generator treatment (per day-unit)	Day-unit	0.40	Equipment embodied carbon, negligible per use
Ozone generator treatment (per day-unit)	Day-unit	0.35	Equipment embodied carbon, negligible per use
Encapsulant / sealant (smoke blocking primer)	Gallon	4.2	EPA EEIO — paint and coating manufacturing
Thermal fogging agent	Liter	2.1	EPA EEIO — chemical manufacturing
HEPA filter (air scrubber)	Each	3.2	EPA EEIO — industrial machinery
Full Tyvek suit (Level C)	Each	1.2	EPA EEIO — apparel manufacturing
Half-face respirator with organic vapor/P100 cartridges (pair)	Pair	0.8	EPA EEIO — medical equipment
Nitrile gloves (pair)	Pair	0.3	EPA EEIO — rubber/plastics

Reconstruction phase materials — installed building components: If your scope includes reconstruction, the embodied carbon of installed materials belongs in Category 1. Use these EPA EEIO factors: drywall $0.42 per board foot × board feet; dimensional lumber $0.55 per board foot; paint and primer $4.2 per gallon. For complex reconstruction, request embodied carbon data from your materials supplier or use the Athena Impact Estimator for buildings as a secondary source.

Category 5: Waste Emission Factors

Waste Type	Disposal Method	tCO2e per ton	Source
Smoke-contaminated C&D debris (non-hazardous)	Standard landfill	0.16	EPA WARM v16
Smoke-contaminated C&D debris (regulated)	Licensed C&D landfill	0.20	EPA WARM + transport premium
Asbestos-containing materials (ACM)	Licensed hazmat landfill	0.38	EPA WARM + hazmat transport + licensed facility
Lead paint debris (regulated)	Licensed hazmat landfill	0.35	EPA WARM + hazmat premium
PCB-containing materials	Licensed hazmat incineration	1.85	EPA hazardous waste incineration factors
Disposable PPE and consumables	Standard landfill	0.25	EPA WARM v16 — mixed plastics

ACM identification rule: If the building was constructed before 1980 and your demolition scope touches floor tiles, ceiling tiles, pipe insulation, or joint compound, assume ACM until tested. Apply the ACM emission factor (0.38 tCO2e/ton) to all potentially ACM-containing demolition waste in buildings where testing was not completed before demolition. Document the assumption in your data quality notes.

Charred and Fire-Damaged Wood Debris: A Critical Correction to Standard Landfill Factors

The standard EPA WARM v16 landfill emission factor for wood debris assumes significant anaerobic decomposition and methane generation in landfill. For fire-damaged and charred structural wood, this assumption is materially incorrect and overstates emissions.

Peer-reviewed measurement studies have established that actual carbon conversion in landfilled wood is 0–19.9% (average ~5%), compared to the IPCC default DOC degradation factor of 50% (Barlaz et al., 2011, Environmental Science & Technology; O’Dwyer et al., 2018, Waste Management). For charred and pyrolyzed wood — the specific material type generated in fire restoration — the correction is even more dramatic. Charring converts cellulose and hemicellulose into stable aromatic carbon structures (chars and graphene-like materials) that are highly resistant to microbial decomposition. Charred wood debris disposed in a landfill produces near-zero methane.

The practical implication for RCP calculations: When calculating Category 5 and Category 12 emissions for fire-damaged structural wood, use the following corrected factors rather than the standard EPA WARM wood debris value:

Material Condition	tCO₂e per short ton (landfill)	vs. EPA WARM Default	Basis
Unburned dimensional lumber (standard)	0.039 (WARM v16)	Baseline	EPA WARM v16
Fire-damaged, smoke-affected (partial char)	0.008–0.015	~65–80% lower	Barlaz et al. 2011; O’Dwyer et al. 2018
Fully charred/pyrolyzed structural members	~0.002–0.005	~87–95% lower	O’Dwyer et al. 2018; char degradation studies

For RCP calculations, use 0.010 tCO₂e per short ton as the default for fire-damaged wood debris when charring is visually confirmed. Document the char condition in the job notes. This correction can meaningfully reduce reported Category 5 and Category 12 emissions on structural fire jobs — in some cases by 60–80% on the wood debris component.

Odor Elimination Equipment: Energy and Emission Data

The Category 1 table above assigns nominal values to ozone and hydroxyl generators. Actual manufacturer specifications reveal a significant difference between the two technologies that affects both emission calculation and equipment selection decisions.

Ozone Generators

Commercial ozone generators used in smoke remediation draw far less power than their effectiveness suggests. The Queenaire QT Hurricane — one of the most widely used units in the industry — operates at 52 watts (0.5A at 120V), covering up to 16,000 sq ft and producing up to 1,600 mg/hr of ozone. Over a typical 24-hour treatment cycle, a single unit consumes only 1.25 kWh. A whole-house treatment using two or three units over two to three days totals approximately 7.5–11.25 kWh. At the national grid emission factor, this yields less than 4 kg CO₂e per treatment — negligible relative to transportation and debris disposal.

Hydroxyl Radical Generators

Hydroxyl generators are a different energy profile. The Odorox Boss draws 230 watts maximum (1.9A at 120V) and treats 1,500–2,500 sq ft. Unlike ozone, hydroxyl generators run continuously while crews are present (safe for occupied spaces during treatment), typically operating three to seven days continuously on larger fire jobs. A single Odorox Boss running five days continuously consumes 27.6 kWh. Multiple units on a commercial job or residential whole-house treatment reach 55–110 kWh per job — a meaningful Domain 1 contribution that should be logged in equipment runtime records.

Updated proxy values replacing EPA EEIO equipment embodied carbon factors:

Equipment	Power Draw	kWh per 24-hr day	kg CO₂e per day (national grid)
Ozone generator (e.g., Queenaire QT Hurricane)	52W	1.25	0.44
Hydroxyl generator (e.g., Odorox Boss)	230W	5.52	1.93

Blasting Media: Corrected Emission Factors

Sodium Bicarbonate (Soda Blasting)

The EPA EEIO chemical manufacturing proxy previously applied to soda blast media significantly understates the actual production footprint. Per a 2019 study in Industrial & Engineering Chemistry Research (Lee et al., KAIST), the Solvay soda ash carbonation process yields approximately 1.69 tonnes CO₂ per tonne NaHCO₃ with full upstream accounting. A simplified proxy via direct carbonation captures 0.32 kg CO₂ per kg. The RCP default for sodium bicarbonate blasting media is 0.5–0.7 kg CO₂e/kg pending manufacturer-specific Environmental Product Declaration data.

Dry Ice Blasting: Corrected Accounting

The FAQ entry above states that CO₂ released during dry ice blasting is included in the production emission factor. This requires a clarification. If the CO₂ used to produce the dry ice is sourced from an industrial byproduct stream — the typical case for commercial dry ice production — only the liquefaction and solidification energy represents a net Scope 3 emission. The sublimated CO₂ itself is not newly generated. Liquefaction adds approximately 39 kWh per tonne of CO₂ processed. At the national grid factor, this adds 13.7 kg CO₂e per tonne of dry ice for energy overhead. The RCP default of 0.85 kg CO₂e/kg remains appropriate as a conservative aggregate estimate but should be updated with supplier-specific data where available.

Generator Fuel: Reference Table for Large Fire Jobs

Extended fire restoration jobs on properties with disrupted electrical service require temporary generator power. Generator fuel consumption is a direct Category 4 emission source and frequently the largest single emission contributor on multi-week structural fire projects.

Generator Size	Fuel consumption at 75% load	kg CO₂ per hour	kg CO₂ per 10-hr day
8 kW diesel	0.54 gal/hr	5.5	55
15 kW diesel	0.94 gal/hr	9.6	96
20 kW diesel	1.30 gal/hr	13.3	133
30 kW diesel	2.40 gal/hr	24.5	245

Source: Hardy Diesel Generator Fuel Consumption Chart; diesel combustion factor 10.21 kg CO₂e/gallon (EPA 2025 EF Hub).

Scale illustration: A typical 20 kW diesel generator running at 75% load for 10 hours per day over a three-week fire restoration project consumes approximately 273 gallons of diesel, producing roughly 2,782 kg CO₂. On a large structural fire job, generator emissions frequently exceed demolition debris disposal as the second-largest emission source after vehicle transportation. Log generator fuel receipts and daily runtime at the job level.

This guide is the working document for calculating Scope 3 greenhouse gas emissions from water damage mitigation jobs under the Restoration Carbon Protocol. It contains the actual emission factors, the calculation methodology for each Scope 3 category, and a complete worked example from a real job type. A contractor who follows this guide will produce a per-job carbon figure that is defensible in a third-party ESG audit.

Job Classification: Why It Matters Before You Calculate

Your emissions total will vary by a factor of 10 or more depending on water category and drying class. Before calculating, classify the job correctly using IICRC S500 definitions:

Category	Source	Emissions Driver	Typical Total Range
Cat 1 / Class 1–2	Clean supply water, limited area	Transportation dominant	0.1–0.5 tCO2e
Cat 2 / Any class	Gray water (washing machine, dishwasher, toilet overflow without feces)	Materials + transportation	0.3–1.5 tCO2e
Cat 3 / Any class	Black water (sewage, floodwater, standing water)	Hazmat disposal + transportation	1.0–8.0 tCO2e
Cat 3 / Class 3–4	Black water, large affected area requiring demolition	All four categories significant	3.0–12.0 tCO2e

Category 4: Transportation Emissions

Transportation is typically the largest or second-largest emission source on water damage jobs. Calculate every vehicle separately.

Emission Factors (EPA Mobile Combustion, 2024)

Vehicle Type	Fuel	kg CO2e per mile	Source
Passenger car / cargo van	Gasoline	0.355	EPA Table 2
Light-duty truck (crew cab, work van)	Gasoline	0.503	EPA Table 2
Light-duty truck	Diesel	0.523	EPA Table 2
Medium-duty truck (equipment trailer)	Diesel	1.084	EPA Table 2
Heavy-duty truck (dump truck, tanker)	Diesel	1.612	EPA Table 2
Heavy-duty truck (loaded, waste hauling)	Diesel	2.25	EPA Table 2 + load factor

Calculation formula: Vehicle miles × emission factor = kg CO2e. Convert to tCO2e by dividing by 1,000.

What counts as “vehicle miles”: Round-trip distance from your facility or previous job to the loss site, multiplied by the number of trips. Include equipment pickup trips, progress check visits, and equipment retrieval trips. Do not include the vehicle miles of subcontractors — their emissions are captured in their own RCP calculation.

Category 1: Materials Emissions

Emission Factors for Common Water Damage Materials

Material	Unit	kg CO2e per unit	Source
Quaternary ammonium antimicrobial (liquid)	Liter	2.8	EPA EEIO — Chemical manufacturing
Hydrogen peroxide-based antimicrobial	Liter	1.9	EPA EEIO — Chemical manufacturing
Desiccant drying agent (silica gel)	kg	1.4	EPA EEIO — Chemical manufacturing
Disposable Tyvek suit (Category B)	Each	1.2	EPA EEIO — Apparel manufacturing
Nitrile gloves (pair)	Pair	0.3	EPA EEIO — Rubber/plastics
N95 respirator	Each	0.4	EPA EEIO — Medical equipment
P100 half-face respirator cartridge (pair)	Pair	0.8	EPA EEIO — Medical equipment
6-mil polyethylene sheeting	m²	0.55	EPA EEIO — Plastics product manufacturing
HEPA filter (air scrubber, standard)	Each	3.2	EPA EEIO — Industrial machinery

Note on antimicrobial volumes: If you don’t track liters applied per job, use these application rate proxies: Cat 2 jobs — 0.015 liters per sq ft of affected area. Cat 3 jobs — 0.025 liters per sq ft (double application typically required).

Category 5: Waste Emissions

Emission Factors by Waste Type and Disposal Method

Waste Type	Disposal Method	tCO2e per ton	Source
Mixed C&D debris (non-hazardous)	Landfill	0.16	EPA WARM v16
Contaminated porous materials (Cat 2)	Landfill (standard)	0.18	EPA WARM v16 + contamination premium
Contaminated porous materials (Cat 3)	Landfill (regulated)	0.22	EPA WARM v16 + hazmat transport
Disposable PPE and consumables	Landfill	0.25	EPA WARM v16 — mixed plastics
Contaminated water (Cat 3)	Municipal wastewater treatment	0.000272 per liter	EPA WARM v16 — wastewater treatment
Contaminated water (Cat 3)	Permitted treatment facility (tanker)	0.000272 per liter + transport	EPA WARM + tanker transport

Estimating waste weight when you don’t have disposal receipts: Use 2.5 lbs per sq ft of demolished drywall (standard 1/2″ drywall), 3.0 lbs per sq ft of demolished flooring (carpet + pad), 0.8 lbs per sq ft of demolished wood subfloor. For Cat 3 contaminated water: estimate from extractor tank fill cycles × tank capacity.

Category 12: Demolished Building Materials

Material	tCO2e per ton (landfill)	tCO2e per ton (recycled)	Source
Gypsum drywall	0.16	0.02	EPA WARM v16
Carpet + pad	0.33	0.05	EPA WARM v16
Hardwood flooring	-0.12 (carbon storage credit)	-0.18	EPA WARM v16
Vinyl/LVP flooring	0.28	0.08	EPA WARM v16 — plastics
Ceramic tile	0.04	0.01	EPA WARM v16 — inert material
Fiberglass batt insulation	0.33	0.05	EPA WARM v16
Cellulose insulation	0.06	-0.02	EPA WARM v16
Dimensional lumber (framing)	-0.07 (carbon storage credit)	-0.15	EPA WARM v16

Important: Negative values for wood-based materials reflect carbon storage credits under EPA WARM methodology — lumber and hardwood store carbon that is not immediately released when landfilled. Apply these credits only if the material is being landfilled rather than incinerated.

Complete Worked Example: Category 2, Class 3 Commercial Water Loss

Job profile: Washing machine supply line failure, 2,400 sq ft commercial office, second floor. Affected area includes cubicle space and server room (contents moved). Required demolition: 800 sq ft drywall, 600 sq ft carpet. Crew: 2 technicians, 3-day mitigation. Your facility is 24 miles from the job site.

Category 4 — Transportation

2 light trucks × 48 miles round trip × 4 trips (initial, day 2, day 3, equipment pickup) = 384 vehicle-miles
384 × 0.503 kg CO2e/mile = 193 kg CO2e

1 equipment trailer (dehumidifiers, air movers) × 48 miles × 2 trips (drop-off + pickup) = 96 vehicle-miles
96 × 1.084 kg CO2e/mile = 104 kg CO2e

1 dump truck for debris × 14 miles to transfer station × 1 trip = 14 vehicle-miles
14 × 2.25 kg CO2e/mile = 32 kg CO2e

Equipment power source: building electrical supply (Scope 2 — property owner, not included here)

Category 4 total: 329 kg CO2e = 0.33 tCO2e

Category 1 — Materials

Quaternary ammonium antimicrobial: 2,400 sq ft × 0.015 L/sq ft = 36 liters × 2.8 kg CO2e/L = 101 kg CO2e

PPE: 2 technicians × 3 days × 2 Tyvek suits/day = 12 suits × 1.2 kg = 14 kg; 2 × 3 × 4 glove pairs = 24 pairs × 0.3 kg = 7 kg; 2 × 3 × 2 N95 = 12 respirators × 0.4 kg = 5 kg. PPE total: 26 kg CO2e

HEPA filter replacement (2 air scrubbers, 1 filter change each): 2 × 3.2 kg = 6 kg CO2e

Category 1 total: 133 kg CO2e = 0.13 tCO2e

Category 5 — Waste

C&D debris (wet materials, Cat 2 contaminated): estimated 1.2 tons (800 sq ft drywall at 2.5 lbs/sq ft = 1,000 lbs; carpet remnants ~400 lbs)
1.2 tons × 0.18 tCO2e/ton = 0.22 tCO2e

Disposable PPE and consumables: ~0.05 tons × 0.25 tCO2e/ton = 0.01 tCO2e

Category 5 total: 0.23 tCO2e

Category 12 — Demolished Building Materials

800 sq ft drywall demolished: 800 × 2.5 lbs = 2,000 lbs = 0.91 tons × 0.16 tCO2e/ton = 0.15 tCO2e

600 sq ft carpet + pad: 600 × 3.0 lbs = 1,800 lbs = 0.82 tons × 0.33 tCO2e/ton = 0.27 tCO2e

Category 12 total: 0.42 tCO2e

Job Total

Category	tCO2e
Category 4 — Transportation	0.33
Category 1 — Materials	0.13
Category 5 — Waste disposal	0.23
Category 12 — Demolished materials	0.42
Total	1.11 tCO2e

This figure — 1.11 tCO2e — is what goes in the Category 4, 1, 5, and 12 rows of the RCP Job Carbon Report delivered to the property manager. The spend-based estimate for a $28,000 job like this (using EPA Services to Buildings factor of approximately 0.10 kg CO2e per dollar) would produce 2.8 tCO2e — more than 2.5x the actual calculated figure. This is why primary data matters.

Antimicrobial and Chemical Emission Factors: Updated Methodology

The EPA EEIO chemical manufacturing factor used in the Category 1 table above is an economic input-output proxy — useful for estimation but not sourced to the actual chemistry. The following replaces or supplements those values where peer-reviewed lifecycle data now exists.

Hydrogen Peroxide-Based Antimicrobials

H₂O₂ is the only restoration antimicrobial with published lifecycle assessment data. The anthraquinone auto-oxidation production process yields 1.33 kg CO₂e per kg of active H₂O₂ (ACS Omega, 2025); the ecoinvent European market average is 1.79 kg CO₂e per kg based on eight producers. For diluted restoration products (typically 3–7.5% concentration), the per-liter emission scales proportionally. A gallon of 7.5% H₂O₂ antimicrobial contains approximately 0.28 kg of active ingredient, yielding roughly 0.37–0.50 kg CO₂e per gallon of diluted product — substantially lower than the EPA EEIO proxy of 1.9 kg CO₂e/liter previously used. Update your calculations accordingly.

Quaternary Ammonium Compounds (QACs)

No cradle-to-gate lifecycle assessment has been published for quaternary ammonium compound production as of April 2026. QACs are petrochemical-derived surfactants manufactured via chloromethane reactions with tertiary amines. The EPA EEIO factor of 2.8 kg CO₂e/liter remains the only available proxy. Flag all QAC calculations as EPA EEIO estimated in the data_quality section of any RCP Job Carbon Report delivered to clients facing SBTi or CSRD verification requirements. The RCP will update this factor when manufacturer-specific LCA data becomes available.

Botanical Antimicrobials (Thymol-Based Products)

Products such as Benefect Decon 30 (thymol active ingredient) carry USDA BioPreferred certification and UL EcoLogo status but no published LCA emission factor as of April 2026. Essential oil distillation is energy-intensive with extremely low extraction yields (1–2% from plant material). The RCP treats botanical antimicrobials as a data gap requiring manufacturer EPD documentation. In the absence of manufacturer data, apply the QAC proxy (2.8 kg CO₂e/liter) and flag as estimated.

Truck-Mounted Extraction Unit: Fuel Consumption Reference Data

Truck-mounted extraction units operate on dedicated gasoline or diesel engines separate from the vehicle drivetrain. The fuel consumed during extraction operations is a direct Domain 2 Category 4 emission source. Manufacturer specifications and field-reported consumption rates:

Unit / Engine	Fuel	Consumption Rate	kg CO₂ per hour
Prochem Peak 500 (Kawasaki FD851D-DFI, 31 HP)	Gasoline	~1.0 gal/hr	8.9
Prochem Everest 870HP (Kubota 75 HP)	Gasoline	1.5–2.5 gal/hr	13.3–22.2
Standard slide-in truckmount (industry consensus)	Gasoline	~1.0 gal/hr	8.9
PTO-driven van-powered (e.g., HydraMaster CDS 4.8)	Gasoline	+1–2 gal/hr above idle	8.9–17.8 (incremental)

RCP proxy for truck mount extraction: 1.0 gallon gasoline per hour of extraction unit operation (8.9 kg CO₂ per hour). A 4-hour extraction job on a standard truckmount generates approximately 35.5 kg CO₂ from the unit alone — independent of the vehicle transportation emissions calculated in Domain 2. Log extraction start/stop times in the job record.

Capture actual fuel consumption from fuel receipts where possible. Where runtime-only is documented, apply the proxy. Flag as proxy in the data_quality section.

Refrigerant Considerations: LGR Dehumidifiers and Fugitive Emissions

Commercial LGR dehumidifiers contain refrigerant charges that are potential Scope 3 emission sources if units are serviced, recharged, or have fugitive leaks. This is not a required RCP data point in v1.0 but is disclosed here for methodological completeness and for contractors with SBTi-committed clients.

Refrigerant Charge Data by Unit Type

Unit	Refrigerant	GWP-100 (AR6)	Approx. Charge
Phoenix DryMAX XL (125 ppd)	R-410A	2,256	~0.68 kg
Phoenix DryMAX (80 ppd)	R-410A	2,256	~0.54 kg
Dri-Eaz Revolution LGR (140 ppd)	R-410A	2,256	~0.60 kg
Dri-Eaz LGR 6000i	R-32	771	Not published

The Dri-Eaz LGR 6000i is the first major restoration dehumidifier using R-32, a refrigerant with a GWP of 771 under IPCC AR6 — representing a 63–67% reduction in refrigerant climate impact compared to R-410A units. This is relevant for the RCP Carbon Reduction Playbook: equipment replacement cycles that prioritize R-32 or R-454B (GWP ~530) units over R-410A materially reduce the fugitive emission exposure of a restoration fleet.

Fugitive emission screening: The EPA default annual leak rate for sealed hermetic refrigeration equipment (residential/commercial A/C) is 10% of charge capacity. For a Dri-Eaz Revolution LGR with 0.60 kg R-410A at the 10% screening rate, the annual fugitive contribution would be 0.06 kg × 2,256 GWP = 135 kg CO₂e per unit per year. Actual leak rates for sealed hermetic dehumidifier compressors are likely 1–5% annually. Contractors are not required to calculate refrigerant emissions under RCP v1.0 but should document unit refrigerant type for RCP v1.1 compliance.

Wastewater Extraction: Methodological Note

Extracted water discharged to municipal sanitary sewer generates indirect emissions at the wastewater treatment facility. Based on Metropolitan Water Reclamation District energy intensity data (Elevate Energy, 2018), the national average wastewater treatment energy intensity is approximately 1,978 kWh per million gallons treated, yielding 0.00074 kg CO₂e per gallon discharged at the national grid emission factor. A typical water damage extraction of 500–2,000 gallons produces only 0.37–1.48 kg CO₂e for wastewater treatment — under 0.5% of total job emissions on most jobs. The RCP excludes this source from required calculation in v1.0 but acknowledges it here for methodological completeness and CSRD-grade reporting contexts.
