EPA further delays 2025 GHGRP submissions

EPA published an interim final rule on October 14, 2026, further extending the submission deadline for the reporting year (RY) 2025 annual greenhouse gas (GHG) report from October 30, 2026, to March 10, 2027.

Who’s impacted?

The final rule applies to facilities subject to the GHG Reporting Program (GHGRP) at 40 CFR Part 98. Generally, three types of entities must report:

• 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 combusted, released, or oxidized; and
• CO₂ injection facilities that inject any amount of CO₂ into the subsurface.

What’s the new deadline?

The interim final rule pushes the submission deadline for the RY 2025 GHG report from October 30, 2026, to March 10, 2027. The delay only applies to the RY 2025 GHG report.

Rule refresher

The GHGRP requirements are based on source categories in the subparts of Part 98. Facilities must report GHG emissions from the previous calendar year for all applicable source categories.

Reporters must use specific methods to calculate GHG emissions, which are detailed in the regulations. Facilities submit the annual GHG report to EPA using the electronic Greenhouse Gas Reporting Tool (e-GGRT).

Key to remember: EPA's interim final rule extends the submission deadline for the 2025 annual GHG report to March 10, 2027.
