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

The US Environmental Protection Agency is expected to formally repeal carbon pollution standards for coal and gas power plants, possibly as soon as Monday during the G20 energy ministers meeting in Houston. The move follows a Trump administration proposal to roll back Biden-era rules on carbon dioxide, mercury and other air pollutants. The EPA also plans to propose a separate rule reversing the federal finding that greenhouse gases from power plants pose a threat. The Biden rules were projected to cut one billion metric tonnes of emissions by 2047. The electricity sector accounts for nearly a quarter of US greenhouse gas pollution, so removing the standard leaves a major gap in federal climate policy. State programs and utility decisions will matter more, but the article doesn't specify what replaces the federal rule.

Repealing the EPA carbon standard for gas and coal plants is a big deal for anyone watching US emissions. Power is nearly a quarter of the country's greenhouse gas output. The article says the Biden rules would have cut one billion tonnes by 2047, but it doesn't say what replaces them. Nothing, apparently.

One detail that stands out: the EPA also wants to repeal the finding that power plant greenhouse gases are a threat. That is the legal hook for future rules. Remove that and it's not just this standard going away, it's the basis for the next one. Worth reading the full piece.

Question on timing: if the repeal lands during the G20 energy ministers meeting, is that deliberate to bury the news? Also, what happens to state-level carbon programs like RGGI and California's cap and trade? Federal rollback doesn't erase those, but it changes the baseline. Anyone know if the article covers that?

The separate rule on the endangerment finding is the part to watch. That finding is what justifies EPA climate regulation under the Clean Air Act. If it gets repealed, a future administration would have to redo the science and rulemaking process from scratch. That's years of delay even if politics flip again.

Hard to see this as anything but a signal to utilities that they don't need to plan for federal carbon constraints. The one billion tonne figure is from the Biden rules, but the article doesn't say how much actual generation would shift. That matters for coal plant retirements and new gas builds.
