3) "EPA Releases Proposal to End the Burdensome, Costly Greenhouse Gas Reporting Program, Saving up to $2.4 Billion", EPA, 9/12/25 ***
-- This story also covered by Reuters, AP News, Axios, Politico, *** 3. EPA Releases Proposal to End the Burdensome, Costly Greenhouse Gas Reporting Program, Saving up to $2.4 Billion
This is a combined summary of reporting from the EPA and Axios on the agency’s proposal to dismantle the Greenhouse Gas Reporting Program (GHGRP).
a) Proposal to end reporting requirements
The EPA announced a plan to eliminate most greenhouse gas reporting obligations under the 15-year-old GHGRP, which currently covers about 8,000 facilities across more than 40 industrial sectors. Administrator Lee Zeldin called the program “bureaucratic red tape” that imposes billions in costs without improving air quality.

Administrator Lee Zeldin called the program “bureaucratic red tape” that imposes billions in costs without improving air quality.
-
Reporting would end for sectors like power generation, steel, refineries, and gas suppliers.
-
Data collection would remain only for facilities subject to the Waste Emissions Charge (WEC), and even that is delayed until 2034.
b) Claimed cost savings and rationale
The EPA estimates the rollback will save regulated industries $2.4 billion total, or roughly $303 million annually between 2025 and 2033. Officials argue resources can be redirected toward tangible environmental improvements instead of paperwork.

-
Trump administration policy emphasizes cutting compliance costs to “unleash energy dominance.”
-
EPA says reporting is not required by the Clean Air Act for most facilities.
c) Strong opposition from lawmakers and industry groups
Democrats and environmental groups blasted the proposal, noting GHGRP data underpins corporate climate disclosures and international competitiveness. Senator Sheldon Whitehouse warned it prioritizes polluters over U.S. industry, while the Carbon Capture Coalition said it jeopardizes billions in investments linked to tax credits for carbon management.

-
Critics argue eliminating data makes it harder to track emissions or qualify for incentives.
-
Expectation of litigation if the rule is finalized.
d) Political and regulatory backdrop
The move aligns with President Trump’s executive orders and broader deregulatory agenda, including earlier efforts to block methane rules. EPA says the rollback maintains statutory obligations while streamlining operations, but opponents frame it as undermining U.S. climate policy at a critical time.
