How Does the Emission Factor Library Work, and Which Databases Are Included?

The CarbonX Emission Factor (EF) Library provides access to more than 500,000 verified emission factors sourced from the world's most trusted environmental and regulatory databases — enabling accurate, current, and standards-aligned GHG calculations.

How It Works

• The CarbonX EF Engine connects directly to multiple authoritative databases, ensuring that every calculation is grounded in the latest available science and regulatory data.

• Emission factors are automatically updated as source databases release new versions.

• Users can search, filter, and select factors by source, sector, region, or year to ensure full methodological transparency.

• All calculations remain traceable, with clear documentation of the EF source and version used.
