EPA Extends 2025 Greenhouse Gas Reporting Deadline to March 10, 2027

What Changed:

On October 14, 2026, EPA published an interim final rule titled “Extending the Reporting Deadline Under the Greenhouse Gas Reporting Rule for Reporting Year 2025 to March 10, 2027” (91 FR 65112). The rule amends 40 CFR 98.3(b)(6) so that the annual GHG report for RY2025 must be submitted no later than March 10, 2027, rather than October 30, 2026.

This is the second extension of the RY2025 deadline. A February 27, 2026 final rule (91 FR 9712) previously moved the deadline from March 31, 2026, to October 30, 2026. The new rule makes no other changes to the Greenhouse Gas Reporting Rule.

Why EPA Extended the Deadline:

EPA gave the following reasons in the rule:

1. Time to consider comments. EPA received more than 50,000 comments on its September 16, 2025 Reconsideration Proposal (90 FR 44591) and stated that it needs additional time to consider them and to finalize any action before the new deadline.
2. Reporting system readiness. EPA stated that its reporting tool, e-GGRT, cannot be ready in time for the October 30, 2026 deadline. EPA normally releases the tool about six weeks before a reporting deadline.
3. Time to adjust to final changes. The extension gives reporters time to adjust to whatever EPA finalizes and avoids wasted effort if most of the proposed rescissions are finalized.

Status of the Reconsideration Proposal:

The September 2025 Reconsideration Proposal would, among other things, eliminate RY2025 reporting obligations. As of October 14, 2026, EPA has not finalized that proposal. EPA’s GHGRP rulemaking page lists no final action on the proposal, and the interim final rule changes only the RY2025 deadline.

Until EPA takes further final action, the RY2025 reporting requirement remains in effect, with the new March 10, 2027 deadline. A later final action could still change RY2025 reporting obligations before that date.

What This Means for Reporters:

• Applicability is unchanged. The rule applies to owners and operators of facilities and suppliers that submit annual GHG reports under 40 CFR Part 98, including direct emitters, suppliers of GHGs or fossil fuels, and entities that sequester carbon dioxide underground. The rule includes a table (Table 1) of covered categories, which EPA notes is not exhaustive.
• The October 30, 2026 deadline no longer applies. The RY2025 annual report is now due March 10, 2027.
• Further changes remain possible. Reporters should monitor EPA’s GHGRP rulemaking page for any final action on the Reconsideration Proposal.

Public Comment:

Comments on the interim final rule are due November 30, 2026, under Docket ID EPA-HQ-OAR-2025-0186. EPA identifies the Federal eRulemaking Portal (regulations.gov) as its preferred submission method. If a public hearing is requested by October 19, 2026, EPA will hold a virtual hearing on October 29, 2026, and speakers must pre-register by October 26, 2026.

Conclusion:

The new deadline gives RY2025 reporters approximately four additional months. Because the Reconsideration Proposal remains pending, the final scope of RY2025 reporting depends on EPA’s further action, and the requirement remains in effect in the meantime.
