Greenhouse Gas Protocol provides the world's most widely used greenhouse gas accounting standards for companies.
GHG Protocol standards and guidance enables companies to measure, manage and report greenhouse gas emissions from their operations and value chains.
In 2016, at least 92% of Fortune 500 companies responding to CDP used GHG Protocol directly or indirectly through a program based on GHG Protocol.

Corporate Standard
The GHG Protocol Corporate Accounting and Reporting Standard provides requirements and guidance for companies and other organizations, such as NGOs, government agencies, and universities, that are preparing a corporate-level GHG emissions inventory.
Corporate Value Chain (Scope 3) Standard
The Corporate Value Chain (Scope 3) Standard allows companies to assess their entire value chain emissions impact and identify where to focus reduction activities.
Product Standard
The Product Standard can be used to understand the full life cycle emissions of a product and focus efforts on the greatest GHG reduction opportunities. This is the first step towards more sustainable products.
Project Protocol
The GHG Protocol for Project Accounting is the most comprehensive, policy-neutral accounting tool for quantifying the greenhouse gas benefits of climate change mitigation projects.

Invitation to Comment: Proposed Addition of Gases Reported with GHG Protocol Standards
GHG accounting is not a static field and the GHG Protocol is constantly reviewing its publications to ensure they properly reflect the science on climate change and continue to define best practices for GHG accounting and management. One area the GHG Protocol monitors is the best available scientific evidence regarding the importance of individual GHGs, as evaluated by the Intergovernmental Panel on Climate Change (IPCC) and as reflected in the guidelines of the United Nations Framework Convention on Climate Change (UNFCCC) for national GHG emissions reporting.
