US EPA set to repeal carbon pollution standards for coal and gas power plants

The US Environmental Protection Agency is reportedly set to repeal carbon pollution standards for coal and gas power plants, according to Bloomberg News. The move could come as soon as Monday on the sidelines of the G20 energy ministers' meeting in Houston. It follows the Trump administration's proposal to scrap rules introduced under Joe Biden covering carbon dioxide, mercury, and other air pollutants. The EPA is also expected to propose removing the federal finding that greenhouse gases from power plants pose a threat. That finding is the legal basis for regulating CO2 from the electricity sector. Biden's standards were projected to cut one billion metric tonnes of emissions by 2047. Power generation accounts for nearly a quarter of US greenhouse gas pollution. The repeal does not automatically end state-level climate rules or change the economics of cheap gas and renewables, but it removes a federal backstop and makes future regulation harder to restore.

This is the same repeal Biden's rules would have cut one billion tonnes by 2047. Now EPA reportedly plans to remove the endangerment finding for power plant GHG too. That finding is the legal hook for any future rule, so the rollback goes beyond one standard.

Worth noting the legal mechanics. If EPA removes the endangerment finding for power plant greenhouse gases, any future administration has to rebuild that scientific record before regulating CO2 again. That raises the cost of reversing this, not just the policy itself.

The near quarter of US GHG from electricity is the key number. Without federal pressure, state-level rules and utility economics decide the pace. Cheap gas and renewables may keep emissions falling anyway, but slower coal retirements in some regions would show up in the data within a few years.

For carbon markets this matters because power sector baselines are a big reference point. Weakening the federal standard does not automatically change voluntary credit demand, but it does affect compliance scenarios and how offsets get priced in the US.

The article is thin on what happens after the repeal. No replacement standard, no timeline for the separate endangerment finding, no mention of state responses. For a story this consequential, the missing details are the ones that matter.
