The Greenhouse Gas Protocol (GHG Protocol) is a comprehensive global standardized framework to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains, and mitigation actions. It was established in 1998 through a partnership between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD).
The GHG Protocol provides tools and standards that help organizations calculate, report, and manage their greenhouse gas emissions. The framework includes several different standards tailored to different types of emissions calculations and reporting needs, such as:
Corporate Standard: This is the core standard for measuring and reporting greenhouse gas emissions from all organizational activities across geographic boundaries. It covers direct and indirect emissions sources and provides the principles and requirements for preparing a corporate-level GHG emissions inventory.
Scope 3 Standard: This standard provides guidance specifically for calculating and reporting Scope 3 emissions, which are the indirect emissions associated with a company’s operations, including both upstream and downstream emissions. It’s designed to help companies assess emissions from their entire value chain.
Product Life Cycle Standard: This standard helps organizations to quantify and report the greenhouse gas emissions associated with individual products throughout their life cycles, from raw material acquisition through production, use, and disposal.
Built Environment Standard: Developed for assessing the emissions from building construction and use, this standard is tailored for real estate developers, owners, occupants, and managers.
Corporate Value Chain (Scope 3) Accounting and Reporting Standard: This is an extension of the corporate standard that provides a detailed framework for assessing Scope 3 emissions.
Guidance for Cities: Provides methodology for cities and local governments to measure and report their greenhouse gas emissions.
These standards are designed to promote economic efficiency and environmental integrity and are widely used by governments and businesses around the world to enhance their sustainability initiatives. They are complemented by a series of other documents and tools that provide additional detail, sector-specific guidance, calculation tools, and reporting frameworks to aid in the effective and consistent accounting of greenhouse gas emissions. The GHG Protocol continues to develop new resources to address evolving needs and sectors, ensuring that its guidance remains comprehensive and applicable across a broad range of contexts and industries.
