EPA Extends 2025 Greenhouse Gas Reporting Deadline to October 30, 2026
The U.S. Environmental Protection Agency (EPA) has issued a final rule extending the reporting deadline under the Greenhouse Gas Reporting Program (GHGRP) for reporting year 2025.
Under the revised rule, regulated entities must now submit their annual greenhouse gas (GHG) reports by October 30, 2026, instead of the previously scheduled March 31, 2026 deadline.
Importantly, this rule only adjusts the reporting timeline. It does not modify, remove, or revise any other existing GHG reporting obligations.
Background: Why the Deadline Was Extended
The GHGRP, codified under 40 CFR Part 98, requires large industrial facilities, fuel and gas suppliers, and CO₂ sequestration sites to report annual emissions data electronically through EPA’s e-GGRT system.
On September 16, 2025, the EPA published a broader proposal titled the “Reconsideration of the Greenhouse Gas Reporting Program.” That proposal sought to:
- Remove reporting requirements for 46 source categories after 2024
- Suspend reporting under Subpart W (petroleum and natural gas systems) until after 2034
- Extend the 2025 reporting deadline to June 10, 2026
The proposal received more than 50,000 public comments, many of which emphasized the need for clarity and certainty regarding reporting timelines.
In response, the EPA finalized only the deadline extension in this rulemaking, deferring decisions on broader structural
changes.
New Reporting Deadline
| Reporting Year | Previous Deadline | Revised Deadline |
|---|---|---|
| 2025 GHG Data | March 31, 2026 | October 30, 2026 |
If the deadline falls on a weekend or federal holiday, submission will be due on the next business day.
What the Final Rule Changes
The EPA amended 40 CFR § 98.3(b) to reflect the extended deadline for reporting year 2025.
No additional compliance requirements, exemptions, or reporting eliminations were finalized. All existing monitoring, calculation, recordkeeping, and reporting obligations remain in effect.
Purpose of the Extension
According to the EPA, the extension aims to:
- Provide regulated entities sufficient time to prepare and verify accurate emissions reports
- Reduce compliance uncertainty while broader program reconsideration continues
- Allow additional time to update and deploy the electronic reporting system (e-GGRT)
Who Is Affected?
The extension applies to all entities currently subject to mandatory reporting under 40 CFR Part 98, including:
- Power plants
- Chemical manufacturers
- Refineries
- Cement plants
- Industrial combustion sources
- Fuel and industrial gas suppliers
- CO₂ injection and sequestration facilities
- Other facilities across 47 source categories
No categories have been removed from the program at this time.
Regulatory Impact
Regulatory Flexibility Act
The EPA certified that the rule does not impose significant economic impacts on small entities because it does not add new requirements—only adjusts the reporting date.
Unfunded Mandates Reform Act
The rule does not create enforceable mandates on state, local, tribal governments, or the private sector.
What Has Not Been Finalized
The EPA has not yet finalized the broader reconsideration proposals, including:
- Eliminating reporting for specific source categories
- Suspending or restructuring parts of the program after 2024
These issues will be addressed in separate future rulemakings.
Practical Implications for Compliance Teams
- Facilities now have nearly seven additional months to compile and submit 2025 GHG data.
- Environmental and sustainability teams can align internal data verification processes with greater certainty.
- Companies should continue preparing reports under existing Part 98 requirements until further notice.
The deadline extension provides temporary regulatory stability while the EPA evaluates the future direction of the Greenhouse Gas Reporting Program.
