Description

This 2026 version of the Emission Factors Hub was produced following the same methodology as the EPA Emission Factors Hub January 2025 release version. This dataset is published here by Cornerstone in the interest of providing emission factors that reflect updated source data for ultimate use in greenhouse gas (GHG) emissions calculations. The data are provided in the same PDF and excel format as previous releases. This release also includes the Emission Factors Hub in a machine readable format.
