EPA extends 2025 GHG reporting deadline
The Environmental Protection Agency (EPA) finalized a rule on February 27, 2026, extending the submission deadline for the 2025 annual greenhouse gas (GHG) report from March to October 2026.
Who’s impacted?
The final rule applies to facilities regulated by the GHG Reporting Program (GHGRP) at 40 CFR Part 98. Generally, the GHGRP’s annual reporting requirement applies to three types of reporters:
- Large industrial sources of GHG emissions (that directly emit 25,000 or more metric tons of carbon dioxide equivalent (CO2e) per year);
- Fuel and industrial gas suppliers (whose products would result in 25,000 or more metric tons of CO2e of GHG emissions per year if released, combusted, or oxidized); and
- CO2 injection facilities (that receive 25,000 or more metric tons of CO2 for injection).
What’s the change?
The final rule extends the submission deadline for the reporting year (RY) 2025 annual GHG report from March 31, 2026, to October 30, 2026. The delay applies only to RY 2025.
EPA explains in the final rule that delaying the submission deadline for the RY 2025 GHG report gives the agency time to take final action on the proposed revisions to the GHGRP (published in September 2025).
What does the GHG report cover?
The GHGRP requires facilities to report GHG data and other related information covering the previous calendar year.
The subparts under Part 98 contain the reporting requirements, and regulated facilities must report emissions for all applicable source categories. Reporters must use specific methods to calculate GHG emissions, which are detailed in the regulations; they can usually choose from a collection of methods.
Key to remember: EPA’s final rule delays the submission deadline for the 2025 annual GHG report from March to October 2026.
