GHG Protocol

Overview

The GHG Protocol establishes the world's most widely used framework for measuring, calculating, and reporting greenhouse gas emissions. It provides standardized methodologies that enable organizations to consistently quantify emissions across operations, value chains, products, and projects.

The framework forms the methodological foundation for a wide range of climate-related reporting initiatives and disclosure requirements. It supports comparability, transparency, and consistency in corporate greenhouse gas reporting, while facilitating informed decision-making by regulators, investors, customers, and other stakeholders.

Within the GRI Global Regulatory Framework, the GHG Protocol is positioned as a leading international greenhouse gas accounting framework supporting climate governance and sustainability disclosure.

Regulatory Sub-Labels

Global Applicability: Global

Classification: Reporting Framework

Status (Framework Status): Active

The GHG Protocol is an internationally recognized greenhouse gas accounting and reporting framework jointly developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). Since the publication of the Corporate Accounting and Reporting Standard in 2001, the framework has expanded through additional standards and guidance covering value chain emissions, product life cycle accounting, project accounting, and other greenhouse gas reporting methodologies. The framework is continuously maintained and updated to reflect evolving business practices and regulatory expectations.

Enforcement (Adoption Mechanism): The GHG Protocol does not impose legally binding obligations on organizations. It is voluntarily implemented by companies and is widely referenced by governments, regulators, stock exchanges, investors, and sustainability reporting frameworks. Many mandatory disclosure regimes and corporate reporting requirements incorporate or align with the GHG Protocol's methodologies.

Last Amended (Latest Framework Version / Update): Continuously updated framework. The GHG Protocol is maintained through the regular publication and revision of standards, guidance documents, technical interpretations, and implementation-related materials. Rather than following a formal amendment procedure as with a treaty, the framework evolves through the ongoing methodological development led by WRI and WBCSD.

Governing Organization: World Resources Institute (WRI) / World Business Council for Sustainable Development (WBCSD)

Business Impact

Supply Chain

The GHG Protocol enables organizations to quantify greenhouse gas emissions across operations and value chains, including Scope 1, Scope 2, and Scope 3 emissions. As a result, the framework has become a foundational basis for supply chain emissions management and supplier engagement.

Compliance

Although voluntary in nature, the framework is widely incorporated into mandatory climate disclosure requirements, procurement programs, investor expectations, and corporate sustainability reporting. Organizations often rely on GHG Protocol methodologies to meet domestic regulatory reporting obligations.

Cost

Implementation may require investment in emissions data collection systems, monitoring processes, supplier engagement, assurance activities, information management, and organizational capacity. These investments improve the quality and reliability of climate-related reporting.

Strategic Implication

The GHG Protocol provides the methodological foundation for corporate decarbonization strategy, climate target setting, transition planning, emissions reduction efforts, and sustainability disclosure. It supports consistent decision-making across global operations and increasingly influences access to capital, customer requirements, and competitive positioning.

Cross Reference

Primary Domain: Climate & Carbon Management. Cross Reference Domain: Environmental Information & Sustainability Disclosure. This Cross Reference reflects the framework's central role in corporate sustainability reporting and climate disclosure. Its Primary Domain, however, remains Climate & Carbon Management in accordance with the One Primary Parent Principle defined in the approved Global Regulatory Instrument Inventory v0.3.

Architecture Position

Within the GRI Regulatory Architecture, the GHG Protocol is registered as a regulatory framework instrument under the Global Climate & Carbon Management Domain.

The framework is designated as a Gateway Reference, serving as one of the primary international entry points to the Global Regulatory Framework. While its methodology is widely applied in sustainability disclosure, its Primary Domain remains Climate & Carbon Management in accordance with the One Primary Parent Principle, with Environmental Information & Sustainability Disclosure expressed through Cross Reference.
