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.
