What Greenhouse Gas Protocol does

Greenhouse Gas Protocol (GHG Protocol) is a global multi-stakeholder standards initiative that develops and disseminates accounting frameworks for measuring and managing greenhouse gas emissions across corporate operations, value chains, and products. Founded in 1997 by World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD), it is jointly managed by those two organizations with offices in Washington, D.C. and Geneva and a combined staff of 501-1,000. Its standards are used by 97% of S&P 500 disclosing companies in their CDP reporting (2023) and by 92% of Fortune 500 respondents (2016), and they form the methodological backbone for major climate disclosure frameworks, mandatory reporting regimes, and target-setting bodies such as SBTi.

The organization's portfolio comprises five core accounting standards — Corporate Standard, Scope 2 Guidance, Corporate Value Chain (Scope 3) Standard, Land Sector and Removals Standard, and Product Standard — alongside the Project Protocol, the in-development Actions and Market Instruments (AMI) Standard, and supplementary Scope 3 Calculation Guidance. Standards are produced through formal multi-stakeholder processes (e.g., 350+ experts on the Corporate Standard, 2,300 participants from 55 countries on the Scope 3 Standard, 300+ external reviewers on the Land Sector and Removals Standard) and distributed as freely downloadable documents via ghgprotocol.org, supported by the Scope 3 Evaluator, calculation tools, third-party life cycle databases, and an E-Learning Platform offering courses in English, Spanish, and French.

GHG Protocol is a non-profit initiative, not a commercial entity; its operating budget is funded through institutional partnerships and a Donor Council comprising Apple, Cargill, Constellation, Deloitte, EY, Generation Foundation, Google, KPMG, Meta, and Toyota. Direct revenue is limited to e-learning course fees (free to $600 per participant) and ancillary services. Major strategic initiatives in 2025-2026 include the ISO Joint Working Group on product-level accounting under the COP30 Action Agenda, the launch of the Land Sector and Removals Standard (effective January 2027), the AMI Standard white paper, and the appointment of Tim Mohin as CEO in April 2026.

Core offering

Greenhouse Gas Protocol develops and disseminates internationally recognized greenhouse gas accounting standards and guidance used by companies, cities, and countries to measure, manage, and report emissions. Its core deliverables include the Corporate Standard, Scope 2 Guidance, Corporate Value Chain (Scope 3) Standard, Land Sector and Removals Standard, Product Standard, and Project Protocol, supported by free calculation tools, third-party life cycle databases, and a fee-based e-learning certification platform for standards-based training.

Product overview

The Greenhouse Gas Protocol (GHG Protocol) is a standards-setting organization that provides a suite of interconnected greenhouse gas accounting standards, guidance documents, and digital tools. The portfolio centers on five core accounting standards: the Corporate Standard (corporate-level GHG inventories), Scope 2 Guidance (energy purchases), Corporate Value Chain (Scope 3) Standard (value chain emissions across 15 categories), Land Sector and Removals Standard (land emissions and CO₂ removals), and Product Standard (product life cycle emissions). These are complemented by the Project Protocol (climate mitigation projects), and the Actions and Market Instruments Standard (currently under development). Supporting the standards are digital tools including the free Scope 3 Evaluator (web-based calculator), downloadable Calculation Tools and Guidance, Third Party Life Cycle Databases, and an E-Learning Platform offering courses ranging from free webinars to paid professional training (up to $600). The portfolio functions as a layered framework — from entity-level to product-level to project-level accounting — enabling companies to measure emissions at every stage of their operations and value chain.

Direct peers

• CDP (formerly Carbon Disclosure Project): CDP operates the world's largest environmental disclosure system and uses GHG Protocol as the foundational accounting standard for its climate questionnaire. 97% of S&P 500 disclosing companies report to CDP using GHG Protocol, making CDP the closest operational partner and adoption channel for GHG Protocol standards.
• Carbon Trust: Carbon Trust is a sustainability consultancy that co-developed GHG Protocol's Scope 3 Calculation Guidance. It provides certification, advisory, and footprinting services built directly on GHG Protocol methodologies, making it a close operational peer for implementation and assurance services.
• Science Based Targets initiative (SBTi): SBTi enables companies to set science-based emissions reduction targets and relies on GHG Protocol standards for the underlying accounting methodologies. The organizations collaborate on FLAG Guidance and other initiatives, making SBTi the most direct partner for target-setting that depends on GHG Protocol accounting.

Broad incumbents

• Global Reporting Initiative (GRI): GRI is the most widely used sustainability reporting standard globally and GRI 305 on emissions cross-references GHG Protocol methodology. GRI competes for the 'default reporting framework' slot in many jurisdictions, making it the most direct competitor for ESG reporting standard adoption.
• Task Force on Climate-related Financial Disclosures (TCFD): TCFD created the foundational framework for climate-related corporate disclosure (now monitored by ISSB). TCFD recommendations explicitly rely on GHG Protocol for emissions metrics, making it a structurally adjacent peer that has shaped the regulatory demand for GHG Protocol-aligned reporting.
• International Organization for Standardization (ISO): ISO is the world's largest developer of voluntary international standards and is now GHG Protocol's formal partner via the 2026 Joint Working Group to harmonize product-level GHG accounting. ISO's existing ISO 14064 family overlaps with GHG Protocol's Corporate and Project standards, making it the most strategically significant incumbent in the standards landscape.
• IFRS Foundation / ISSB: The ISSB (within the IFRS Foundation) issues IFRS S2 Climate-related Disclosures and increasingly references GHG Protocol as the underlying emissions accounting methodology. As ISSB becomes the global baseline for sustainability disclosure, its alignment with GHG Protocol reinforces GHG Protocol's authority over how Scope 1-3 are measured.
• SASB (Sustainability Accounting Standards Board, now part of IFRS Foundation): SASB developed industry-specific sustainability accounting standards that are now housed within the IFRS Foundation. SASB standards reference GHG emissions metrics aligned with GHG Protocol, making it a structurally adjacent disclosure standard whose sector-specific approach partially overlaps with GHG Protocol's product and corporate frameworks.

Others

• World Resources Institute (WRI): WRI is one of the two parent organizations co-managing GHG Protocol (alongside WBCSD), providing institutional hosting, research capacity, and global reach. WRI is not a competitor but rather the operational backbone whose strategy, funding, and governance priorities directly shape GHG Protocol's trajectory.

Emerging players

• Watershed: Watershed is a leading commercial enterprise carbon accounting platform that implements GHG Protocol methodologies (Scope 1-3) and offers MRV, reduction planning, and audit-ready reporting. It represents the private-software layer built on top of GHG Protocol's free standards, and is the most credible private-sector alternative for the implementation tier.
