Your Progress
Section 1 of 5What is the GHG Protocol?
The GHG Protocol provides standards, guidance, tools, and training for business and government to measure and manage climate-warming emissions. It's the world's most widely used greenhouse gas accounting standard, adopted by thousands of organizations globally.
The framework establishes comprehensive global standardized approaches to measuring and reporting GHG emissions from private and public sector operations, value chains, products, cities, and policies.
Comprehensive Coverage
The GHG Protocol covers all major greenhouse gases (CO₂, CH₄, N₂O, HFCs, PFCs, SF₆, NF₃) and provides methodologies for different types of organizations and activities.

Interactive Emission Source Explorer
Select emission sources to see how they contribute to different scopes. This helps understand where your organization's emissions come from.
Scope 1 Sources
Scope 2 Sources
Scope 3 Sources
Why Scopes Matter
Understanding emission scopes helps organizations prioritize reduction efforts. Scope 3 often represents the largest portion of emissions but can be the most challenging to address.
GHG Protocol Advantage
The GHG Protocol provides standardized methods to measure and report emissions across all scopes, enabling consistent comparisons and effective climate action planning.
