The short answer: if your facility reports under the EPA’s Greenhouse Gas Reporting Program, your 2025 report is now due March 10, 2027 — not October 30, 2026. The EPA moved the deadline for the second time in a year, in an interim final rule effective October 14, 2026, and it changed nothing else. The reason for the move is the story: the agency is still deciding whether the 2025 report should exist at all.
What exactly changed
One date. The interim final rule (Federal Register, October 14, 2026, document 2026-20982) extends the reporting deadline for reporting year 2025 under the Greenhouse Gas Reporting Rule (40 CFR Part 98) from October 30, 2026 to March 10, 2027. In the EPA’s own words, the action “only changes the reporting deadline for annual greenhouse gas reports for reporting year 2025 and makes no other changes to the rule.”
The rule took effect the day it published. The EPA is accepting comments on it until November 30, 2026 (Docket ID EPA-HQ-OAR-2025-0186, via regulations.gov).
How the deadline got here: three moves in thirteen months
| Date | What happened | RY2025 deadline after the move |
|---|---|---|
| Standing rule | GHGRP annual reports are due March 31 each year, filed through the e-GGRT system | March 31, 2026 |
| September 16, 2025 | EPA proposes reconsidering the whole program (90 FR 44591) — including a proposal that no industries would need to submit reports for calendar year 2025 at all. The proposal draws over 50,000 comments | June 10, 2026 (proposed) |
| February 27, 2026 | EPA final rule (91 FR 9712) extends the deadline to buy time on the reconsideration | October 30, 2026 |
| October 14, 2026 | Interim final rule extends it again, expressly so EPA can finish weighing those comments and take final action on the reconsideration first | March 10, 2027 |
Read the sequence for what it is: the agency has now twice declined to collect a report it is actively considering abolishing. The March 2027 date is real, and it is also a placeholder in a fight about whether the program continues in anything like its current form.
Who this actually applies to
Not every building owner — and it matters to know which side of the line you are on. The Greenhouse Gas Reporting Program covers owners and operators of facilities that report under 40 CFR Part 98: large direct emitters, fuel and industrial-gas suppliers, and carbon sequestration sites. Most commercial buildings never file.
The category that catches building owners is general stationary fuel combustion — facilities running large boilers, process heaters, turbines, and engines. The EPA’s own list of affected entities for this rule includes health services and educational services: a big hospital campus or university with a central plant can be a Part 98 reporter. If your organization has filed through e-GGRT before, this deadline is yours. If you have never filed, a deadline extension for a program you are not in changes nothing for you directly — though the signals below still apply.
The decision the delay actually creates
A moved deadline is not a cancelled one. Three things are true at once, and a sensible owner plans around all three:
- The obligation still stands. Until the EPA finalizes the reconsideration, reporting year 2025 remains a required report with a due date of March 10, 2027. Treating the extension as a repeal is a bet, not a reading of the rule.
- The repeal is genuinely possible. The September 2025 proposal would have eliminated the 2025 reporting obligation entirely. If the final action lands anywhere near the proposal, the March 2027 deadline may never be used. The EPA took this extension specifically to finish that decision before the deadline arrives.
- Your 2025 data has other masters. The fuel records, meter data, and calculations behind a federal report are the same records that state programs, lenders, insurers, tenants, and corporate ESG disclosures ask for — on their own schedules, none of which paused. The cheapest time to assemble 2025 data was while 2025 was happening; the second-cheapest time is now, while the records are still warm.
The practical posture: stop the scramble, keep the file. You no longer need a finished report by the end of October. You do need your 2025 fuel and emissions records gathered, consistent, and retrievable — because every plausible ending (program retained, program narrowed, program ended but state and market demands continuing) rewards the owner who kept the data and penalizes the one who used the delay as a reason to discard it.
Frequently asked questions
What is the new deadline for 2025 greenhouse gas reports?
March 10, 2027. The EPA’s interim final rule of October 14, 2026 moved it from October 30, 2026. It is the second extension for reporting year 2025; the original due date was March 31, 2026.
Did the EPA cancel 2025 GHG reporting?
No. The EPA has proposed eliminating the 2025 reporting obligation as part of its reconsideration of the Greenhouse Gas Reporting Program, and it received over 50,000 comments on that proposal. Until a final action is published, the report remains required — just due later.
Does this affect building owners?
Directly, only if your facility reports under 40 CFR Part 98 — most often large properties with substantial on-site fuel combustion, such as hospital campuses, universities, and industrial sites. Most individual commercial buildings are not GHGRP reporters. Indirectly, the data discipline still matters: state programs and private ESG requests use the same underlying records and have not paused.
Can I comment on the rule?
Yes. Comments on the interim final rule are due by November 30, 2026, under Docket ID EPA-HQ-OAR-2025-0186, through regulations.gov. Most individual owners will feel the outcome more than they shape it; industry associations are the realistic channel for owner input.
What should a reporting facility do now?
Re-calendar the deadline to March 10, 2027, keep the 2025 data collection intact, and watch for the final reconsideration action — it, not this extension, decides whether the report is ever filed.
