Green-e Climate

Step 1 – Review the Green-e Climate Standard Download and read the current Green-e Climate Standard and accompanying program documents from green-e.org to understand eligibility requirements, approved project standards, and disclosure obligations.

Step 2 – Confirm Eligibility Verify that the carbon offsets you sell are sourced from projects certified under a Green-e-approved standard (e.g., Verra VCS, Gold Standard, American Carbon Registry, Climate Action Reserve). Only retail sellers of offsets — not project developers — are eligible.

Step 3 – Complete the Application Submit a certification application to the Center for Resource Solutions (CRS). The application requires information about your business, the offset products you sell, the underlying project standards, and your retirement and disclosure practices.

Step 4 – Prepare Documentation Gather sales transaction records, credit retirement documentation, and all marketing and communications materials that reference your carbon offsets. These will be reviewed during the verification process.

Step 5 – Undergo the Verification Audit An independent third-party verifier reviews your sales data and retirement records to confirm that the correct volume and type of offsets were retired on behalf of customers during the reporting period.

Step 6 – Complete the Marketing Compliance Review (MCR) CRS reviews your marketing and communications materials to ensure all claims are accurate, complete, and compliant with Green-e Climate disclosure requirements.

Step 7 – Receive Certification and Display the Mark Upon successful completion of both review components, you are authorized to display the Green-e Climate mark on certified products and marketing materials and will be listed in the Green-e online registry.

Step 8 – Renew Annually Repeat the Verification Audit and MCR each year to maintain certification in good standing.

Green-e Climate evaluates offset sellers across two primary compliance dimensions rather than a scored point system.

1. Offset Quality and Chain of Custody Offsets sold under the Green-e Climate mark must originate from projects certified under a Green-e-approved project-level standard, such as the Verified Carbon Standard (Verra VCS), Gold Standard, American Carbon Registry (ACR), or Climate Action Reserve (CAR). The Verification Audit confirms that the correct volume and vintage of credits were retired — not just purchased — on behalf of end customers, and that no double-counting occurred. Retirement must happen in the appropriate registry account and within required timeframes.

2. Marketing and Disclosure Compliance The Marketing Compliance Review (MCR) evaluates all customer-facing materials — websites, product descriptions, invoices, advertising, and social media — against Green-e Climate's disclosure requirements. Sellers must accurately represent what customers are buying, including the project type, location, vintage, and the certification status of the offsets. Claims must not be misleading, and the Green-e mark may only be used in approved ways.

3. Operational and Recordkeeping Practices Sellers must maintain adequate records of all transactions, retirements, and customer communications to support the annual audit. CRS may also review internal processes to confirm that operational practices align with program requirements.

The program does not use a tiered scoring system — certification is binary. A seller either meets all requirements and is certified, or must remediate deficiencies before certification is granted or maintained.

Green-e Climate is the most widely recognized consumer-protection certification for retail carbon offsets in the United States. Administered by the Center for Resource Solutions — a nonprofit with deep roots in renewable energy certificate (REC) markets — the program leverages the strong brand equity of the broader Green-e family, which also includes Green-e Energy, the leading REC certification in North America. This brand recognition gives Green-e Climate a credibility advantage over newer or less-established offset quality marks, particularly among U.S. corporate buyers and sustainability-focused consumers.

The voluntary carbon market has experienced significant turbulence since 2022, with high-profile investigative journalism questioning the quality of widely used offset project types (particularly REDD+ forest protection credits) and growing scrutiny of greenwashing claims. This environment has simultaneously increased demand for credible third-party certification and raised the bar for what buyers consider acceptable. Green-e Climate benefits from this dynamic, as its chain-of-custody and disclosure requirements directly address the transparency gaps that critics have highlighted. However, the program certifies the seller and transaction — not the underlying project — meaning it is complementary to, rather than a replacement for, project-level standards like Verra VCS or Gold Standard.

Internationally, Green-e Climate's reach is primarily North American. Global buyers and sellers may look to frameworks like the Integrity Council for the Voluntary Carbon Market (ICVCM) Core Carbon Principles or the Voluntary Carbon Markets Integrity Initiative (VCMI) for broader international credibility. Demand for retail offset certification is also being shaped by evolving regulatory guidance from the FTC (Green Guides) and SEC climate disclosure rules, both of which increase the legal and reputational stakes of unverified offset claims — a trend that supports continued relevance for programs like Green-e Climate.

Green-e Climate was established in 2008 by the Center for Resource Solutions (CRS), building on the success of Green-e Energy, which CRS had launched in 1997 as the first independent certification program for renewable energy in the United States. As the voluntary carbon offset market grew rapidly in the mid-2000s — driven by corporate sustainability commitments and consumer interest in climate action — CRS identified a need for the same kind of consumer-protection framework it had developed for RECs. Green-e Climate was designed to address the lack of transparency and quality assurance in the retail offset market, where buyers had little ability to verify whether the offsets they purchased were real, additional, and properly retired.

The program has evolved alongside the voluntary carbon market, updating its approved project standards list and disclosure requirements as the market has matured. Governance of the Green-e Climate Standard is overseen by the independent Green-e Governance Board, which includes representatives from environmental organizations, businesses, and other stakeholders — a structure designed to insulate standard-setting from commercial pressures on CRS as program administrator. Over its history, Green-e Climate has become a reference point for corporate procurement policies and has been cited in FTC guidance discussions as an example of credible third-party offset certification.
