Why did the EPA move the 2025 greenhouse gas reporting deadline to March 2027?

The EPA has moved the reporting year 2025 Greenhouse Gas reporting deadline from October 30, 2026, to March 10, 2027. According to Impakter, the change comes through an interim final rule that postpones submission only. It does not repeal reporting obligations or alter other requirements. Facilities that were preparing to file by the end of this month now have a little over four additional months.

The scope of the change is narrow but the context is not. Impakter notes that the EPA is separately considering whether to remove or suspend much of the programme. That pending decision is the real uncertainty for reporters. A deadline extension on its own is administrative relief. A decision to remove or suspend large parts of the programme would reshape what US facility level emissions data is publicly available and what companies are required to collect.

For European companies with US operations, the practical advice is to avoid treating the delay as a reason to stop preparing. The obligations stand, and the interim final rule leaves other requirements unchanged. Data collection, verification, and internal sign off processes should continue on their existing schedule, since the extra time may be withdrawn or made moot depending on what the agency decides next. Groups that consolidate US facility data into global Scope 1 figures for CSRD purposes should also confirm which data sources their group reporting depends on.

The linkage to European reporting is worth stating carefully. ESRS E1 and the GHG Protocol Scope 1 and 2 approach do not depend on the EPA programme, and a company's CSRD disclosures remain its own responsibility. However, many multinationals use the same underlying facility data for several regimes, and a change in what is filed in the United States can alter what peers and investors can benchmark against. Teams that rely on public US datasets for supplier or competitor comparisons should expect gaps if the wider programme is cut back.

What to watch is the EPA's separate decision on whether to remove or suspend much of the programme. The source does not give a date for it. Until it arrives, the sensible posture is to treat March 10, 2027 as the working deadline, keep the data pipeline running, and document any assumptions that depend on the programme continuing in its current form.
