  • GRESB vs CDP vs SB 253: Which ESG Framework Actually Governs Your Property Portfolio

    GRESB vs CDP vs SB 253: Which ESG Framework Actually Governs Your Property Portfolio

    Property owners and asset managers in institutional real estate operate in an increasingly layered ESG disclosure environment. GRESB drives investor-facing ESG scoring. CDP provides voluntary supply chain disclosure that is increasingly investor-requested. California SB 253 mandates Scope 3 disclosure for large entities. And the EU’s Corporate Sustainability Reporting Directive (CSRD) extends mandatory ESG reporting to European operations and, through supply chain due diligence requirements, reaches global real estate companies with EU exposure.

    For BOMA members — building owners, REITs, asset managers — understanding which framework governs which obligations, and where they overlap, is essential for building an ESG program that satisfies all of them without duplicating work. This article maps each framework against the specific Scope 3 obligations it creates for property owners, with particular focus on the contractor supply chain data gap that sits at the intersection of all three.

    GRESB: Investor-Driven, Asset-Level, Annual

    GRESB is the primary ESG accountability mechanism for institutional real estate globally. It is not a regulation — it is an investor-driven benchmark that most institutional property owners participate in voluntarily because their capital partners require it. GRESB assessments are annual, asset-level, and scored on a 0–100 scale that investors use to compare portfolio ESG performance.

    For Scope 3, GRESB evaluates both governance (do you have a Scope 3 target and supply chain policy?) and performance (do you have actual Scope 3 data?). Contractor emissions — Scope 3 Category 1 — factor into both components. Property owners without contractor data collection programs score lower on supply chain governance and leave Category 1 data fields blank in the Performance section.

    GRESB is the most immediate Scope 3 pressure for most BOMA members because it directly affects your capital relationships. A poor GRESB score can affect asset valuations, borrowing costs, and investor mandates in ways that regulatory compliance does not.

    CDP: Voluntary, Supply Chain Driven, Escalating

    CDP’s supply chain program allows large corporations — including real estate companies’ major tenants and capital partners — to request Scope 3 supply chain data from their vendors. For property owners, CDP requests typically arrive from two directions: from institutional tenants whose corporate ESG programs require supply chain data from their landlords, and from institutional investors whose own CDP commitments require portfolio-level Scope 3 supply chain data.

    CDP participation is voluntary, but declining a CDP request from a major tenant or capital partner has commercial consequences. As CDP participation expands — the program now covers thousands of companies — the probability that a significant counterparty will request Scope 3 data from your organization continues to increase.

    California SB 253: Mandatory, Regulated, Enforced

    SB 253 is the only mandatory framework in this set, at least for US-domiciled organizations. It applies to entities doing business in California with revenues above the threshold, requires Scope 1 and 2 disclosure starting with fiscal year 2025 data, and adds Scope 3 starting with fiscal year 2026 data. CARB administers the program and has authority to assess penalties for non-compliance and material misstatement.

    For real estate entities with California assets, SB 253 transforms the Scope 3 contractor data question from an investor relations consideration into a legal compliance obligation. The same contractor emissions data that improves your GRESB score and satisfies CDP supply chain requests now also needs to be accurate enough to withstand CARB review.

    Where Restoration Contractor Data Fits in Each Framework

    The Restoration Carbon Protocol addresses the same data gap across all three frameworks. An RCP-compliant restoration contractor provides project-level emissions data in a format aligned with GHG Protocol Category 1. That data feeds directly into your GRESB Performance section, satisfies CDP supply chain data requests for Category 1, and provides the documented, methodology-backed Scope 3 Category 1 data that SB 253 requires.

    The strategic efficiency argument for RCP adoption by property owners is that solving the restoration contractor data problem once solves it for all three frameworks simultaneously. You do not need different data for GRESB, CDP, and SB 253 — you need GHG Protocol Category 1 data, and RCP produces it in that format.

    Building a Unified Response

    For BOMA members navigating GRESB, CDP, and SB 253 simultaneously, the most efficient path is a unified Scope 3 data program rather than three separate compliance efforts. The foundation is a GHG Protocol-aligned inventory methodology that covers all fifteen Scope 3 categories. Contractor data — collected through RCP-compliant vendor agreements and green lease extensions — feeds into that inventory once and satisfies all three frameworks.

    The timeline pressure is real: SB 253 Scope 3 data collection for fiscal year 2026 should already be underway, GRESB 2026 assessments will open in the first quarter, and CDP supply chain requests arrive year-round. The property owners who have built the contractor data infrastructure now — preferred vendor panels with RCP adoption, ESG clauses in service agreements, documented methodology — will be the ones with defensible Scope 3 inventories when all three frameworks converge on the same data set in 2027.

    Frequently Asked Questions

    Does GRESB require the same data as SB 253?

    Both require Scope 3 GHG data aligned with the GHG Protocol Corporate Standard. GRESB collects it through an annual assessment submitted to the benchmark platform. SB 253 requires public disclosure filed with CARB. The underlying data set is the same — a GHG Protocol-compliant Scope 3 inventory by category — which is why building one unified inventory program satisfies both frameworks efficiently.

    How does CSRD affect US-based property owners?

    The EU’s Corporate Sustainability Reporting Directive (CSRD) applies directly to large EU-domiciled companies and EU subsidiaries of non-EU companies above defined thresholds. For US-based real estate companies with EU operations or EU-listed capital partners, CSRD may apply directly. Even for those it does not reach directly, CSRD’s supply chain due diligence requirements mean EU-based capital partners and tenants will increasingly request Scope 3 supply chain data from their US counterparties as part of their own CSRD compliance.

    What is the Restoration Carbon Protocol and why do BOMA members need it?

    The Restoration Carbon Protocol (RCP) is an industry self-standard that gives restoration contractors a structured GHG accounting methodology for project-level emissions reporting. For BOMA members, RCP-compliant contractors provide the Scope 3 Category 1 data needed for GRESB performance scores, CDP supply chain responses, and SB 253 mandatory disclosure — in a format directly compatible with GHG Protocol reporting requirements.

  • Green Lease 2.0: How Property Owners Can Use Lease Language to Drive Scope 3 Contractor Compliance

    Green Lease 2.0: How Property Owners Can Use Lease Language to Drive Scope 3 Contractor Compliance

    Green leases have been a standard tool in the institutional real estate ESG toolkit for over a decade. Originally designed to align landlord and tenant incentives around energy efficiency, green lease clauses have evolved to cover data sharing, sustainability reporting, and — in more sophisticated agreements — explicit GHG emissions obligations.

    The same contractual logic that makes green leases effective for tenant emissions management can be applied to the contractor supply chain. Property owners who have invested in green lease programs for tenant Scope 3 (Category 13) data now have a parallel opportunity: using vendor agreement language to systematically collect Scope 3 Category 1 data from the contractors who perform work on their assets.

    What Green Lease Language Has Achieved — and Where It Stops

    Modern green lease frameworks — developed by BOMA, the Institute for Market Transformation, the Urban Land Institute, and others — have established standard clauses for energy data sharing, sub-metering requirements, sustainable operations standards, and ENERGY STAR reporting. These clauses give property owners a contractual mechanism to collect the tenant data needed for GRESB Category 13 reporting and corporate GHG inventories.

    Green leases stop at the tenant boundary. They do not govern the contractors the property owner engages for capital projects, maintenance, and emergency response. Those contractor relationships are covered by master service agreements, purchase orders, and emergency vendor panel arrangements — none of which have traditionally included GHG data reporting requirements.

    Extending the Logic: Contractor ESG Clauses

    The Green Lease 2.0 framework extends the proven lease-language approach to contractor agreements. The principle is identical: establish a contractual data delivery obligation, specify the format and methodology, and make compliance a condition of the vendor relationship.

    For restoration contractors specifically, the relevant clause structure covers three elements. A methodology requirement — specifying that the contractor must use a recognized GHG accounting methodology (such as the Restoration Carbon Protocol) for calculating project emissions. A data delivery requirement — specifying that a project emissions report in a format compatible with GHG Protocol Category 1 reporting must be delivered within 30 days of project completion. And a pre-qualification requirement — specifying that participation in the property owner’s preferred restoration vendor panel requires demonstrated GHG reporting capability prior to emergency deployment.

    Why the Pre-Qualification Step Matters

    The most important element of the contractor ESG clause framework is pre-qualification — establishing GHG reporting capability before the loss event occurs. Property owners cannot negotiate data requirements at 2 AM when a pipe bursts. The contractual infrastructure needs to exist before the emergency.

    Pre-qualification creates a preferred vendor panel of restoration contractors who have adopted RCP or an equivalent methodology and are contractually committed to delivering project emissions data. When a loss event occurs, the property manager calls from that panel — and GHG data collection is already built into the engagement.

    What This Looks Like for GRESB and SB 253

    For GRESB participants, a documented contractor ESG clause program with demonstrated adoption across your preferred vendor panel satisfies the supply chain governance requirements in the Management component of the GRESB assessment. It shows that your organization has policies in place, that those policies have contractual teeth, and that you are actively collecting contractor emissions data — not estimating it.

    For SB 253, the contractor ESG clause approach provides the documented data collection methodology that CARB’s guidance suggests as the evidentiary standard for Scope 3 Category 1 reporting. Organizations that can demonstrate a systematic contractor data collection program — rather than spend-based estimation — are better positioned for both initial compliance and the audit scrutiny that mandatory disclosure programs inevitably generate over time.

    Green Lease 2.0 is not a dramatic reinvention. It is the application of a framework that already works — for tenants — to the contractor relationships where property owners have an equivalent data obligation and an equivalent contractual lever to close it.

  • The Restoration Carbon Protocol: A Property Owner’s Guide to Contractor Scope 3 Data

    The Restoration Carbon Protocol: A Property Owner’s Guide to Contractor Scope 3 Data

    Property owners managing large commercial real estate portfolios have made significant progress on Scope 1 and Scope 2 emissions. Energy management systems, green building certifications, and utility procurement strategies have given asset managers real tools for reducing and reporting direct and indirect energy emissions. Scope 3 Category 1 — the contractor supply chain — has been the persistent blind spot.

    The Restoration Carbon Protocol (RCP) is designed to close the most acute piece of that gap: the emissions generated by restoration contractors during loss events and emergency response projects. This article explains what the RCP covers, how it generates the data property owners need, and how to integrate it into your ESG program and vendor management processes.

    Why Restoration Contractors Are a Unique Scope 3 Challenge

    Most contractor Scope 3 challenges can be addressed through procurement policy — adding ESG reporting requirements to RFPs, master service agreements, and annual vendor reviews. This works for planned, recurring vendor relationships where you control the selection process and the contract terms.

    Restoration contractors operate differently. They are engaged reactively, after a loss event. The property manager calls whoever is on the emergency vendor panel. The contractor mobilizes immediately. There is no competitive procurement, no ESG pre-qualification review, and no time to negotiate reporting requirements before work begins. The emissions happen regardless of whether data is collected.

    This is why the RCP matters: it establishes the data collection methodology on the contractor’s side, before the loss event. A contractor who has adopted the RCP arrives at your property already equipped to generate the emissions data you need — no negotiation required at the time of loss.

    What the RCP Measures

    The Restoration Carbon Protocol covers four primary emissions categories for a typical restoration project. Equipment fuel consumption — diesel generators, drying equipment, dehumidifiers, extraction units, and vehicles — is measured against hours of operation and fuel consumption logs. Materials with embedded carbon — replacement drywall, flooring, insulation, and structural components — are estimated using industry-standard embodied carbon factors. Waste generation — demolition debris, contaminated materials, and packaging — is tracked by weight and disposal method. Transportation — contractor vehicle miles, equipment hauling, and materials delivery — is calculated using distance and load data.

    The RCP output is a project-level emissions report expressed in metric tons of CO2 equivalent, broken down by category. That format maps directly to GHG Protocol Scope 3 Category 1 reporting requirements — making it usable for GRESB data submissions, CDP supply chain responses, and SB 253 Scope 3 inventory filings.

    How to Ask Your Vendors About RCP

    For property owners building RCP adoption into their vendor management process, the conversation with restoration contractors has three components. First, ask whether the contractor has adopted the RCP or an equivalent GHG reporting methodology — this establishes whether data collection infrastructure exists. Second, ask what the output format looks like and whether it maps to GHG Protocol Category 1 — this determines whether the data is actually usable for your reporting obligations. Third, ask about the delivery timeline — GRESB, CDP, and SB 253 all require annual inventory data, and you need project-level data within the fiscal year it occurred.

    Contractors who have not adopted RCP but are aware of it may be willing to do so if a significant client requests it. The RCP is an industry self-standard, not a certification program with fees or audits — the barrier to adoption is methodology, not cost.

    Integrating RCP Data into Your ESG Program

    Once you have RCP-compliant contractors on your preferred vendor panel, the data integration is straightforward. Each completed project generates an emissions report. Those reports are aggregated annually by property and portfolio. The totals feed into your Scope 3 Category 1 inventory alongside data from other contractor categories. The result is a documented, methodology-backed contractor emissions number — not a spend-based estimate — that satisfies the evidentiary standard for GRESB, CDP, and SB 253 reporting.

    For BOMA members managing portfolios under institutional ESG frameworks, this is the difference between a defensible Scope 3 inventory and a gap that investors, auditors, and regulators will flag. The RCP does not solve the entire contractor Scope 3 problem — but it solves the most unpredictable piece of it, and it does so in a format property owners can actually use.

  • California SB 253 and Real Estate: What Property Owners Must Demand from Restoration Contractors

    California SB 253 and Real Estate: What Property Owners Must Demand from Restoration Contractors

    California’s Climate Corporate Data Accountability Act (SB 253) has been widely discussed in the context of large manufacturers and technology companies. Less discussed — but equally significant — is the exposure it creates for real estate entities. Property owners, REITs, and asset managers with California operations and revenues above the threshold face mandatory Scope 3 disclosure beginning with fiscal year 2026 data, due in 2027.

    For BOMA members managing California commercial real estate, SB 253 changes the contractor relationship in a material way. The restoration contractor who responds to a water loss event at your San Francisco office tower, your Los Angeles industrial park, or your San Diego mixed-use development is generating Scope 3 Category 1 emissions that will need to appear in a mandatory public disclosure. And that contractor almost certainly has no mechanism for providing you that data today.

    Who SB 253 Applies To

    SB 253 applies to entities doing business in California with total annual revenues exceeding $1 billion. The law is administered by the California Air Resources Board (CARB). For Scope 3, the first reporting year is fiscal year 2026 — meaning data collection for Scope 3 needs to begin now for organizations that have not already started.

    Many institutional real estate owners — national REITs, pension fund asset managers, sovereign wealth fund-backed property companies — clear the revenue threshold and have California assets. For these entities, SB 253 Scope 3 reporting is not a future consideration. It is an active compliance requirement with a defined first filing date.

    The Reactive Vendor Problem for Real Estate

    SB 253’s Scope 3 requirement covers all fifteen GHG Protocol categories. For property owners, Category 1 (Purchased Goods and Services) includes every contractor engaged during the reporting year — planned maintenance vendors, capital project contractors, and reactive emergency-response vendors like restoration companies.

    The planned vendor relationship is manageable. You can add ESG data reporting to your master service agreements with recurring maintenance contractors, HVAC firms, and janitorial services. You can build it into your RFP process and annual vendor reviews.

    Reactive vendors are the structural problem. You do not choose when a pipe bursts or when a fire damages a tenant floor. You do not run a competitive procurement when a Category 1 water loss event hits your building at 2 AM. The restoration contractor who shows up is whoever your property manager calls — and the emissions from their equipment, materials, and transportation are your Scope 3 Category 1 obligation regardless of whether they provide data or not.

    The Restoration Carbon Protocol as a Compliance Bridge

    The Restoration Carbon Protocol (RCP) was developed specifically to address the reactive vendor data gap. It provides restoration contractors with a standardized methodology for calculating project-level GHG emissions across equipment fuel consumption, materials, waste, and transportation — and for communicating that data to property owner clients in a format aligned with GHG Protocol Category 1 requirements.

    For SB 253 compliance purposes, an RCP report from your restoration contractor provides the documented, methodology-backed data needed to populate your Scope 3 Category 1 inventory for loss events. Without it, your organization faces the CARB-specified alternative: estimation using spend-based methods — which typically overstate emissions and provide no path to reduction.

    What to Put in Your Vendor Agreements Now

    For California property owners preparing for SB 253 Scope 3 compliance, three vendor agreement changes directly address the restoration contractor gap. Add a GHG data delivery requirement to your preferred restoration vendor agreements, specifying RCP-compliant project emissions reports as a deliverable within 30 days of project completion. Add an ESG pre-qualification question to your emergency vendor panel selection process, asking whether candidates have adopted RCP or an equivalent methodology. And brief your property managers on the new data requirement — so that when a loss event occurs, GHG data collection is part of the project closeout process, not an afterthought six months later during annual reporting.

    SB 253 enforcement has a ramp period, but the data collection requirement is retroactive to fiscal year 2026. The time to build the vendor data pipeline is now, before the loss events that will generate the data you need occur.

  • GRESB and Scope 3: What Property Owners Must Report and Where Contractors Fit

    GRESB and Scope 3: What Property Owners Must Report and Where Contractors Fit

    For property owners and asset managers in institutional real estate portfolios, the Global Real Estate Sustainability Benchmark (GRESB) is not optional — it is the standard by which your ESG performance is measured, scored, and reported to institutional investors. And as GRESB’s scoring methodology continues to align with TCFD, ISSB, and the GHG Protocol, Scope 3 supply chain data has moved from a nice-to-have to a measurable gap in your assessment score.

    This article examines exactly where contractor Scope 3 data fits in the GRESB Real Estate Assessment, what the consequences of a data gap look like in practice, and how the Restoration Carbon Protocol (RCP) gives property owners a direct path to closing it.

    How GRESB Measures Scope 3

    The GRESB Real Estate Assessment is structured around two components: Management (governance, policy, targets, and reporting) and Performance (actual environmental and social data). Scope 3 emissions surface in both.

    In the Management component, GRESB evaluates whether your organization has a GHG emissions reduction target that includes Scope 3, and whether your supply chain policies address emissions reporting from contractors and vendors. Property owners without explicit contractor emissions standards in their procurement policies lose points here.

    In the Performance component, GRESB collects actual GHG data at the asset level — and Scope 3 Category 1 (Purchased Goods and Services, including contractors) is part of the expected data set for organizations reporting under GHG Protocol Corporate Standard.

    The Contractor Data Gap in Practice

    Most property owners managing large portfolios have reasonable visibility into Scope 1 (direct combustion at owned assets) and Scope 2 (purchased electricity). The contractor supply chain is where the inventory breaks down.

    Restoration contractors are among the highest-emission vendor categories in a property owner’s supply chain — yet they are engaged reactively, after loss events, and almost universally lack any mechanism for providing GHG data to their clients. A commercial building fire or flood event that triggers a six-figure restoration project will generate significant Scope 3 Category 1 emissions. Those emissions belong in your GRESB data. In most cases, they are simply missing.

    What RCP-Compliant Contractors Provide

    The Restoration Carbon Protocol gives restoration contractors a standardized methodology for calculating and communicating project-level emissions data — covering equipment fuel consumption, materials with embedded carbon, waste generation, and transportation. RCP output maps directly to GHG Protocol Category 1 reporting requirements.

    For GRESB participants, this means an RCP-compliant restoration contractor can provide the data needed to populate your Scope 3 Category 1 inventory for loss events — closing a gap that most property owner GHG inventories currently leave blank. That data supports your GRESB Performance score and demonstrates supply chain governance maturity in the Management component.

    Tenant Emissions: The Category 13 Problem

    While contractor data is the most actionable gap for most BOMA members, tenant emissions represent the largest Scope 3 exposure in most property portfolios. GRESB specifically evaluates whether property owners collect tenant energy and emissions data — and whether green lease clauses are in place to facilitate that collection.

    The contractor and tenant problems are structurally similar: both involve third parties operating within your assets whose emissions appear in your Scope 3 inventory, but whose data collection you do not directly control. Green leases address the tenant side. Contractor ESG requirements in your procurement standards — and RCP adoption by your preferred vendor panel — address the contractor side.

    Practical Steps for GRESB Participants

    For property owners currently completing or preparing for GRESB assessments, three actions directly improve your Scope 3 contractor data position. First, add an ESG data reporting requirement to your preferred vendor agreements — specifying that contractors must provide project-level GHG data in a format compatible with GHG Protocol Category 1 reporting. Second, ask your preferred restoration contractors whether they have adopted the Restoration Carbon Protocol or a comparable methodology. Third, build contractor emissions data into your post-loss project closeout process — making GHG reporting a deliverable alongside cost documentation and certificate of completion.

    These are not theoretical improvements. They are the specific steps that convert a data gap in your GRESB Performance section into a documented, improving metric — the kind institutional investors recognize as evidence of genuine ESG program maturity rather than checkbox compliance.

  • BOMA vs IFMA: Why Scope 3 ESG Looks Completely Different for Property Owners

    BOMA vs IFMA: Why Scope 3 ESG Looks Completely Different for Property Owners

    When the sustainability conversation turns to Scope 3 emissions, property owners and facility managers are often lumped together. Both manage buildings. Both hire contractors. Both face regulatory pressure from California SB 253, CSRD, and investor frameworks like GRESB and CDP. But the obligations, the data gaps, and the strategic levers are fundamentally different depending on which side of the lease you sit on.

    BOMA members — building owners, asset managers, and property managers — occupy a distinct position in the Scope 3 landscape. You own or control the asset. Your tenants generate Scope 3 emissions inside your buildings under Category 13 (Downstream Leased Assets). Your contractors generate Scope 3 emissions during capital projects and maintenance under Category 1 (Purchased Goods and Services). And your investors increasingly require you to disclose both — through GRESB assessments, CDP supply chain requests, and emerging mandatory frameworks.

    The Core Distinction: Asset Owner vs. Building User

    IFMA’s membership is primarily the corporate occupier — the facility manager who runs operations inside a building their employer leases or owns for non-real-estate purposes. Their Scope 3 exposure is Category 1: what they buy, including the contractors they hire for restoration, maintenance, and capital projects.

    BOMA’s membership is the asset side of that equation. As a property owner, your Scope 3 inventory is more complex:

    • Category 1 (Purchased Goods and Services): Contractors you hire — restoration companies, mechanical contractors, janitorial services, construction firms during capital improvements
    • Category 13 (Downstream Leased Assets): Your tenants’ energy consumption and operations inside your building — the hardest Scope 3 category to measure and the one GRESB scrutinizes most closely
    • Category 11 (Use of Sold Products): For REITs and developers who sell or transfer properties

    The tenant emission problem is uniquely a BOMA problem. Your tenants control the space. They set the thermostat, they bring in their own contractors, they determine actual energy consumption. But under GHG Protocol rules for property owners, their emissions may appear in your Scope 3 inventory — and GRESB will ask about them.

    The Contractor Data Gap: Where BOMA and IFMA Converge

    Here is where BOMA and IFMA face the same structural problem: restoration contractors, mechanical service firms, and specialty trade vendors who perform work on your properties have no standardized mechanism for reporting their Scope 3 emissions data back to you.

    When a water damage event triggers a restoration project — emergency extraction, structural drying, mold remediation — the contractor mobilizes equipment that burns diesel, deploys materials with embedded carbon, and generates waste. All of that falls under your Scope 3 Category 1. And almost none of it gets captured in any formal emissions inventory.

    The Restoration Carbon Protocol (RCP) is an emerging industry self-standard designed to fix this. It gives restoration contractors a structured methodology for calculating and communicating Scope 3 emissions data to their property owner clients — in a format that maps directly to GHG Protocol Category 1 reporting requirements.

    GRESB and the Asset Manager Accountability Stack

    For BOMA members managing assets in institutional portfolios, GRESB is the primary accountability mechanism. The GRESB Real Estate Assessment scores assets on environmental, social, and governance performance — and Scope 3 supply chain data is an increasingly weighted component.

    GRESB participants who cannot provide contractor Scope 3 data leave points on the table. More importantly, as GRESB scoring evolves to align with TCFD and ISSB frameworks, the absence of supply chain data will increasingly flag as a material gap to institutional investors.

    Green Leases: The BOMA Lever IFMA Doesn’t Have

    One strategic lever available to property owners that IFMA FMs typically lack is the lease itself. Green lease clauses — requirements embedded in tenant agreements around energy reporting, contractor ESG standards, and waste management — give asset managers a contractual mechanism to drive Scope 3 data collection that facility managers simply cannot replicate.

    The Institute for Market Transformation’s Green Lease Leaders program and BOMA’s own sustainability frameworks both provide templates. The opportunity is to extend the same logic to contractor agreements — requiring vendors like restoration companies to provide RCP-compliant emissions data as a condition of contract.

    What This Series Covers

    This BOMA Scope 3 series on Tygart Media examines the Scope 3 challenge specifically through the property owner and asset manager lens. We cover GRESB reporting obligations, green lease strategy, SB 253 and CSRD compliance for real estate entities, and the contractor data gap that sits at the intersection of both the BOMA and IFMA worlds.

    The RCP thread runs through all of it — because whether you are a corporate occupier FM or a property owner, the restoration contractor showing up after a loss event is generating Scope 3 emissions that belong in someone’s inventory. This series is about making sure yours is complete.

    Frequently Asked Questions

    Does GRESB require Scope 3 Category 1 contractor data?

    GRESB’s Real Estate Assessment includes supply chain and contractor emissions as part of its environmental data collection. While the specific weighting evolves annually, institutional investors using GRESB increasingly expect property owners to demonstrate Scope 3 supply chain visibility. Gaps in contractor data weaken your GRESB score and signal portfolio risk to asset managers.

    How is a property owner’s Scope 3 different from a tenant’s?

    Property owners report Scope 3 from the asset ownership perspective — including downstream tenant emissions (Category 13), upstream contractor supply chain (Category 1), and capital project emissions. Tenants report from the occupier perspective — primarily Category 1 for their own purchased services. The same building can appear in both inventories under different Scope 3 categories.

    What is the Restoration Carbon Protocol and why does it matter to BOMA members?

    The Restoration Carbon Protocol (RCP) is an industry self-standard that gives restoration contractors a structured framework for calculating and reporting the Scope 3 Category 1 emissions associated with their work. For BOMA members, RCP-compliant contractors provide the data needed to close the contractor gap in your GHG inventory — supporting GRESB reporting, CDP responses, and SB 253 compliance.

  • GRESB vs CDP vs SB 253: Which ESG Framework Actually Governs Your FM Operations

    GRESB vs CDP vs SB 253: Which ESG Framework Actually Governs Your FM Operations

    If you are a facility manager trying to understand your Scope 3 ESG obligations, you have almost certainly encountered three acronyms that sound similar but operate very differently: GRESB, CDP, and SB 253. Each one creates real obligations for FM operations — but they apply to different organizations, require different data, and serve different audiences. This article maps the landscape so you can determine which frameworks govern your program and what each one specifically requires from your contractor data collection.

    GRESB: The Asset-Level Framework

    GRESB (the Global Real Estate Sustainability Benchmark) is an investor-driven ESG assessment framework for real estate portfolios. It is primarily used by property owners, REITs, and real estate investment managers who need to demonstrate sustainability performance to institutional investors.

    Who it primarily affects: BOMA-type property owners and real estate investors. If you are an FM at a corporate occupier — a company that uses its buildings for operations, not as investment assets — GRESB is typically your asset manager’s problem, not yours.

    What it asks about contractors: GRESB’s Real Estate Assessment includes questions about green building certifications, energy performance, and sustainability policies for construction and renovation projects. It does not currently have a Scope 3 contractor data requirement comparable to GHG Protocol Category 1. However, GRESB is evolving its framework to incorporate more supply chain data as investor pressure increases.

    IFMA relevance: Low to medium, unless your corporate occupier organization owns its real estate portfolio and participates in GRESB as both occupier and investor. In that case, GRESB and GHG Protocol obligations overlap.

    CDP: The Voluntary Disclosure Framework

    CDP (formerly the Carbon Disclosure Project) operates a global disclosure system that allows companies to report their environmental data to investors, purchasers, and the public. CDP’s Supply Chain program specifically requests Scope 3 data from suppliers — which means your organization may receive CDP questionnaires from your own customers asking about the emissions associated with the services you provide to them.

    Who it primarily affects: Companies that participate voluntarily in CDP disclosure, and companies whose corporate customers require supplier CDP responses. CDP is used by many large corporate occupiers as a sustainability disclosure mechanism.

    What it asks about contractors: CDP’s corporate questionnaire includes Scope 3 Category 1 disclosure. If your organization reports to CDP, you are expected to include Category 1 emissions from your contractors — including restoration vendors — in your response. CDP accepts activity-based and spend-based estimates; it also tracks year-over-year improvement in data quality.

    IFMA relevance: High for FM teams at organizations that participate in CDP or whose parent companies have signed CDP commitments. CDP is often the first Scope 3 reporting pressure FM teams experience, because it is voluntary but publicly visible — investors and customers can see whether your organization reports and how complete your data is.

    SB 253: The Mandatory Disclosure Framework

    California SB 253 — the Climate Corporate Data Accountability Act — is mandatory, not voluntary. It requires companies with over $1 billion in annual revenue doing business in California to disclose Scope 1, 2, and 3 emissions on a phased schedule: Scope 1/2 starting in 2026 (for fiscal year 2025 data), Scope 3 starting in 2027 (for fiscal year 2026 data). Reports must be independently verified by a CARB-registered third-party auditor.

    Who it primarily affects: Any company doing business in California with over $1 billion in annual revenue. This is a wide net — it captures many large corporate occupiers regardless of headquarter location.

    What it asks about contractors: SB 253 uses GHG Protocol methodology, which requires reporting all material Scope 3 categories. Category 1 (contractors and suppliers) is a mandatory category under the GHG Protocol for most organizations. Restoration contractors are a Category 1 source. SB 253’s independent verification requirement means your auditor will scrutinize the quality of your Category 1 data — spend-based estimates will be accepted but flagged as lower quality than activity-based data.

    IFMA relevance: High for FM teams at large corporate occupiers doing business in California. This is the framework with the hardest deadline and the most compliance consequence.

    EU CSRD: The European Mandatory Framework

    For completeness: the EU Corporate Sustainability Reporting Directive (CSRD) applies to large EU companies and, in some cases, non-EU companies with significant EU operations or revenue. CSRD requires disclosure under the European Sustainability Reporting Standards (ESRS), which include Scope 3 under ESRS E1. Like SB 253, it requires third-party verification and covers supply chain emissions.

    IFMA relevance: High for FM teams at multinational corporate occupiers with European operations. CSRD and SB 253 overlap in their Scope 3 requirements, meaning data infrastructure built for one framework largely serves both.

    What This Means for Contractor Data Collection

    If your organization is subject to SB 253, or participates in CDP, or both — you need Category 1 contractor data. The specific data points required are the same across all three frameworks because they all use GHG Protocol methodology as their basis. Building a contractor data collection process that satisfies GHG Protocol Category 1 requirements will satisfy SB 253, CDP, and CSRD simultaneously.

    The Restoration Carbon Protocol is designed to produce exactly that data. Its output — the per-job RCP Carbon Report — maps to Category 1 inputs for all three frameworks. FM teams that implement RCP-compliant vendor requirements do not need to build separate data collection processes for each framework.

    Frequently Asked Questions

    If my company participates in GRESB, do I still need to collect contractor Scope 3 data?

    GRESB’s current framework focuses on asset-level energy and water performance rather than supply chain Scope 3 data. However, if your organization also participates in CDP or is subject to SB 253 or CSRD, those frameworks require contractor Category 1 data regardless of GRESB participation. Check which frameworks your sustainability team is reporting to.

    Can I use one dataset to satisfy multiple frameworks?

    Yes. Because GRESB, CDP, SB 253, and CSRD all use GHG Protocol methodology as their technical basis, data collected to satisfy one framework’s Scope 3 Category 1 requirements is compatible with the others. Build the data collection process once; use it across all frameworks your organization reports to.

  • How to Build a Scope 3 Contractor Compliance Checklist for Your FM Program

    How to Build a Scope 3 Contractor Compliance Checklist for Your FM Program

    Scope 3 compliance for facility managers is fundamentally a vendor management problem. You cannot calculate your Category 1 emissions without data from your contractors, and you cannot get data from contractors without a systematic process for requesting, receiving, and storing it. This article provides a practical checklist for building that process — one that works for FM teams of any size and scales as your contractor pool grows.

    Phase 1: Vendor Inventory and Prioritization

    Before you can build a Scope 3 data collection process, you need to know which contractors generate material emissions on your behalf. Not all vendors are equal Scope 3 risks — prioritize based on emission intensity and spend.

    Step 1: Map your contractor categories

    List every category of contractor your FM program engages. For most corporate FM teams, the highest emission-intensity contractor categories are:

    • Emergency restoration (water, fire, mold, hazmat) — diesel-heavy equipment, waste streams, episodic but high-intensity
    • Construction and tenant improvements — embodied carbon in materials, significant waste
    • HVAC maintenance and retrofits — refrigerant handling, combustion equipment
    • Grounds and landscaping — fuel-burning equipment, fertilizer (N₂O emissions)
    • Janitorial and facility services — lower intensity but high volume

    Step 2: Score by emission intensity × annual spend

    Multiply each category’s estimated emission intensity (high/medium/low) by your annual spend in that category. The highest-scoring categories are your priority Scope 3 data gaps. Emergency restoration typically scores high on intensity even when annual spend is variable, because a single large water damage event can generate a meaningful emissions figure.

    Phase 2: Vendor Qualification Updates

    Step 3: Add Scope 3 capability questions to RFP and vendor qualification forms

    For new vendor solicitations, add the following questions to your qualification criteria:

    • Does your organization track greenhouse gas emissions associated with individual project work?
    • Are you familiar with GHG Protocol Scope 3 Category 1 methodology?
    • Have you adopted the Restoration Carbon Protocol (for restoration vendors)?
    • Can you provide a per-project emissions summary upon project completion?
    • What job management system do you use, and does it support emissions data export?

    Step 4: Tier your existing vendors

    Survey your existing contractor pool with the same questions. Categorize vendors into three tiers: Tier 1 (already tracking emissions data), Tier 2 (willing to adopt a framework with support), and Tier 3 (unable or unwilling to provide data). Tier 3 vendors become a procurement risk factor — flag for transition to Tier 1 or 2 alternatives at contract renewal.

    Phase 3: Contract Language

    Step 5: Add Scope 3 data provisions to new contracts

    For restoration contractors specifically, reference the Restoration Carbon Protocol as the accepted methodology standard. For other contractor categories, reference GHG Protocol Scope 3 Category 1 methodology and specify the data fields required. Include:

    • Obligation to provide a per-project emissions summary within 30 days of completion
    • Minimum data fields required (fuel, vehicle miles, waste type and weight, equipment hours)
    • Accepted methodology standard (RCP for restoration; GHG Protocol Category 1 for others)
    • Data format and delivery method (PDF report, CSV, or API-compatible format)
    • Right to audit contractor data collection processes during the contract term

    Phase 4: Data Collection and Storage

    Step 6: Establish a receiving process for contractor emissions reports

    Decide where contractor emissions data will live in your FM systems. Options include: a dedicated folder in your CMMS work order system attached to each job record, a shared ESG data repository managed by your sustainability team, or a direct integration with your ESG reporting platform. The key is that every restoration job has an associated emissions record — not a separate tracking system you have to reconcile at year-end.

    Step 7: Build a gap-filling protocol for missing data

    Some contractors will not provide data even after you request it. Build a proxy calculation protocol for data gaps using spend-based or activity-based estimation. The RCP provides proxy tables for restoration jobs. For other categories, the GHG Protocol’s Scope 3 Calculation Guidance provides spend-based emission factors you can apply to invoice data.

    Phase 5: ESG Inventory Integration

    Step 8: Integrate contractor data into your annual Scope 3 Category 1 calculation

    At the end of each fiscal year, compile all contractor emissions reports and proxy estimates into your Scope 3 Category 1 input. Document your methodology, note which vendors provided primary data and which required proxy estimation, and flag any material gaps for disclosure in your ESG report. Most third-party ESG auditors will accept a documented methodology with known limitations more readily than an unexplained data gap.

    The Checklist Summary

    • ☐ Map contractor categories by emission intensity and annual spend
    • ☐ Score and prioritize: emergency restoration at the top
    • ☐ Add Scope 3 capability questions to vendor qualification forms
    • ☐ Tier existing vendors (1=tracking, 2=willing, 3=unable)
    • ☐ Add Scope 3 data provision clause to new contracts (reference RCP for restoration)
    • ☐ Establish data receiving process in your CMMS or ESG platform
    • ☐ Build proxy protocol for data gaps
    • ☐ Integrate into annual Scope 3 Category 1 calculation with documented methodology

  • The Restoration Carbon Protocol: What Facility Managers Need to Know

    The Restoration Carbon Protocol: What Facility Managers Need to Know

    If you manage facilities for a corporate occupier and you have been trying to figure out how to get Scope 3 emissions data from your restoration contractors, the Restoration Carbon Protocol (RCP) exists to answer that question. This article explains what the RCP is, how it works, and what IFMA members specifically need to know about using it as a procurement and compliance tool.

    What the Restoration Carbon Protocol Is

    The RCP is an industry self-standard published by Tygart Media that defines how restoration contractors should calculate, document, and report the greenhouse gas emissions associated with each project they complete. It is built on the GHG Protocol’s Corporate Value Chain (Scope 3) Standard — the same framework used by most corporate ESG reporting programs and required by SB 253 and CSRD.

    The RCP fills a specific void: no restoration industry body — not IICRC, not RIA, not any trade association — had previously published a Scope 3 reporting methodology for restoration work. Commercial property managers and corporate FM teams asking their restoration vendors for emissions data were getting blank stares. The RCP gives contractors the methodology and gives FM procurement teams the standard to reference.

    The Five Core Restoration Job Types and Their Scope 3 Mapping

    The RCP maps each of the five primary restoration job types to the relevant GHG Protocol Scope 3 categories:

    • Water damage restoration: Category 1 (services purchased), Category 5 (waste from extracted water and contaminated materials)
    • Fire and smoke restoration: Category 1 (services), Category 5 (soot, char, and demolition debris waste streams)
    • Mold remediation: Category 1 (services), Category 5 (contaminated building materials removed)
    • Asbestos and hazmat abatement: Category 1 (services), Category 5 (regulated waste disposal), Category 4 (specialized transport)
    • Biohazard cleanup: Category 1 (services), Category 5 (medical and biological waste streams)

    In all five cases, the primary Scope 3 category for the FM client is Category 1 — Purchased Goods and Services. The emissions are generated by the contractor performing work on your behalf at your facility.

    The 12 Data Points: What to Ask Your Contractor to Track

    The RCP defines 12 data points that a restoration contractor should capture on each job to enable a complete Scope 3 calculation. As an FM procurement professional, these are the data fields you should be requiring in your vendor agreements:

    1. Total diesel consumed by drying and dehumidification equipment (gallons)
    2. Total propane or natural gas consumed by heat drying equipment (cubic feet or gallons)
    3. Total vehicle miles traveled to and from the site by all crew vehicles
    4. Number of crew vehicle trips and vehicle types (van, pickup, box truck)
    5. Total equipment operating hours (by equipment category)
    6. Weight of water extracted and removed from the site (gallons or pounds)
    7. Weight and type of contaminated materials removed (drywall, insulation, flooring, etc.)
    8. Disposal method for each waste stream (landfill, recycling, hazardous waste facility)
    9. Refrigerants used, recovered, or vented (for HVAC-adjacent work)
    10. Materials installed by type and weight (for reconstruction phases)
    11. Cleaning agents and chemical products used by product category
    12. Total project duration in days

    Not every data point is relevant to every job type. The RCP provides job-type-specific templates that pre-populate the relevant fields for water, fire, mold, hazmat, and biohazard jobs respectively.

    How FM Teams Can Use the RCP Framework

    There are three practical ways IFMA members can incorporate the RCP into their FM operations:

    1. Vendor Qualification

    Add RCP awareness to your restoration vendor qualification checklist. Ask prospective vendors whether they have adopted the RCP framework. Vendors who can demonstrate RCP familiarity are already capturing the data you need; vendors who cannot are a data gap risk for every job they complete.

    2. Contract Language

    Include a Scope 3 data provision clause in restoration vendor agreements referencing the RCP as the accepted methodology standard. This gives vendors a concrete deliverable (the RCP Job Carbon Report) rather than an open-ended “emissions data” request they have no idea how to fulfill.

    3. Scope 3 Inventory Integration

    Route the per-job RCP carbon reports from your restoration vendors into your Scope 3 Category 1 data collection system. Most ESG reporting platforms (Watershed, Persefoni, Salesforce Net Zero Cloud, etc.) accept Category 1 supplier data in standardized formats. The RCP report is designed to map directly to these platforms’ input requirements.

    The RCP Is Free to Use

    The Restoration Carbon Protocol is published as an open industry standard. There is no licensing fee, no certification requirement, and no vendor lock-in. FM teams can share the RCP framework directly with their restoration vendors at no cost. Contractors can adopt the RCP’s data capture templates and calculation methodology without purchasing anything.

    The goal is adoption — the more restoration contractors who begin tracking RCP-compliant data, the more complete FM Scope 3 inventories become across the industry.

    Frequently Asked Questions

    Is the RCP recognized by IICRC or RIA?

    The RCP is an independent industry self-standard published by Tygart Media. It is not currently endorsed by IICRC or RIA, as neither body has published a competing ESG standard. The RCP fills the void those bodies have not addressed. FM teams and restoration contractors can adopt it independently without waiting for official industry body endorsement.

    How does a restoration contractor become RCP-certified?

    The RCP v1.0 includes a self-certification checklist. Contractors complete the checklist to demonstrate they have implemented the required data capture processes and calculation methodology. Third-party verification is available for organizations that require audited certification. Details are published at tygartmedia.com/category/esg-restoration/.

  • How California SB 253 Changes What Facility Managers Must Demand from Restoration Vendors

    How California SB 253 Changes What Facility Managers Must Demand from Restoration Vendors

    California’s Climate Corporate Data Accountability Act — SB 253 — is the most consequential piece of corporate climate disclosure legislation in the United States. For facility managers at large corporate occupiers, its Scope 3 provision creates a specific and urgent vendor management problem that most FM teams have not yet fully reckoned with.

    What SB 253 Actually Requires

    SB 253 requires companies with annual revenues exceeding $1 billion that do business in California to publicly disclose their greenhouse gas emissions. The disclosure schedule is phased:

    • Scope 1 and Scope 2: First reports due in 2026 (covering fiscal year 2025 data)
    • Scope 3: First reports due in 2027 (covering fiscal year 2026 data)

    The California Air Resources Board (CARB) is the administering body. Reports must be independently verified by a third-party auditor. The law applies to any company doing business in California — not just California-headquartered companies — which means the net is significantly wider than the state’s own corporate population.

    This is not a voluntary framework. SB 253 carries penalties for non-compliance. The Scope 3 provision is the one that creates a direct operational problem for FM teams, because Scope 3 data lives outside your organization — in your contractors’ job management systems.

    The Contractor Data Chain

    Under the GHG Protocol’s Scope 3 framework — which SB 253 uses as its methodological basis — your restoration contractors are a Category 1 (Purchased Goods and Services) supplier. Every time you hire a restoration company to respond to a water intrusion event, a fire damage claim, or a mold remediation project, that contractor’s emissions for that job are technically part of your Scope 3 inventory.

    The calculation is not optional. The GHG Protocol requires organizations to make a reasonable effort to quantify all material Scope 3 categories. For a large corporate occupier with a substantial real estate portfolio, emergency restoration is a recurring and quantifiable Category 1 exposure. Your ESG auditor will ask about it. Your SB 253 filing will need to account for it.

    Why Most Restoration Contractors Cannot Provide This Data Today

    The restoration industry has no Scope 3 standard. IICRC — the primary certification body for restoration professionals — has no ESG reporting guidance. RIA has no Scope 3 framework. Most restoration contractors manage their operations through job management software that tracks labor hours, materials, and job costs — not emissions.

    This is not negligence; it is a gap that simply has not been filled until now. The Restoration Carbon Protocol (RCP) is the first industry self-standard that defines how restoration contractors should calculate and report their Scope 3 emissions data. It gives contractors the methodology, the data capture template, and the calculation framework — and it gives FM procurement teams the standard they can reference in vendor contracts.

    What to Put in Your Vendor Agreements Now

    The most practical SB 253 preparation step for FM procurement teams is to update restoration vendor agreements to include a Scope 3 data provision clause. Here is the language framework:

    “Vendor agrees to provide a per-project greenhouse gas emissions summary for each project completed at Client facilities, using a documented calculation methodology consistent with GHG Protocol Scope 3 Category 1 guidelines. The summary shall include: total fuel consumption by equipment type, vehicle miles traveled, waste materials removed by type and weight, and total equipment operating hours. Submissions shall be provided within 30 days of project completion.”

    This clause does not require contractors to be ESG experts. It requires them to track and report the underlying data points from which a Scope 3 calculation can be made. Contractors who have adopted the RCP framework already capture this data as part of their standard job documentation.

    The Retroactive Data Problem

    SB 253 requires disclosure for fiscal year 2026 data, meaning the clock is already running. If your organization does business in California and exceeds the revenue threshold, your restoration vendors should be tracking Scope 3 data for jobs completed throughout 2026. Waiting until late 2026 to request this data will result in gaps that your ESG auditor will flag.

    For restoration jobs already completed in 2025 and early 2026, proxy-based estimation is acceptable under GHG Protocol methodology when primary data is unavailable. The RCP provides proxy calculation tables for each restoration job type, allowing FM teams to estimate historical emissions from basic job records (square footage treated, job duration, equipment type). This is not ideal, but it is methodologically defensible and far better than a data gap.

    The SB 253 Compliance Checklist for FM Teams

    1. Confirm whether your organization meets the SB 253 threshold (>$1B revenue, does business in California)
    2. Identify all restoration and specialty trade contractors in your vendor pool as Category 1 Scope 3 sources
    3. Update vendor agreements with a Scope 3 data provision clause (language above)
    4. Share the RCP framework with active vendors so they understand what data to capture
    5. Establish a process for collecting and storing per-job emissions summaries in your FM system
    6. Engage your ESG consultant to integrate contractor data into your Scope 3 Category 1 calculation methodology
    7. Plan for third-party verification of your Scope 3 data — auditors will scrutinize Category 1 more than any other category

    Frequently Asked Questions

    Does SB 253 apply if my company is not headquartered in California?

    Yes. SB 253 applies to any company that “does business in California” and meets the revenue threshold. This is broadly interpreted to include companies with California employees, customers, or operations — even if they are incorporated and headquartered elsewhere.

    What is the penalty for non-compliance with SB 253 Scope 3 provisions?

    CARB has authority to assess administrative penalties for non-compliance. The specific penalty structure is being finalized through rulemaking. Consult your legal counsel for the current enforcement guidance applicable to your organization.

    Can I use a spend-based methodology for restoration contractor Scope 3 data?

    Spend-based estimation (using economic input-output data) is permitted under GHG Protocol methodology as a fallback when primary or activity-based data is unavailable. However, third-party auditors generally flag spend-based estimates as lower quality than activity-based calculations. For a recurring Category 1 source like restoration contractors, building toward activity-based data is the appropriate goal.
