President Donald Trump supports the coal industry and denies climate change, so it surprised few last year when he announced his intention to kill the Clean Power Plan, the Obama administration’s aggressive regulations to limit greenhouse gas emissions from coal-fired power plants.

The surprising part came months later. In December, the Environmental Protection Agency said it wouldn’t entirely undo Obama’s coal-emission regulations. The Clean Power Plan would be replaced with a new plan—a weaker one, to be sure, but with emissions limits nonetheless. But it turns out that Trump’s plan might be worse than no plan at all.

On Tuesday, the EPA unveiled its replacement regulation: The Affordable Clean Energy (ACE) Rule. Unlike the Clean Power Plan, which set hard limits on carbon emissions from the coal industry (and has yet to be implemented due to court challenges), Trump’s rule would allow individual states to create their own emissions-reduction goals and plans. By the EPA’s own analysis, replacing Obama’s plan with Trump’s would result in as many as 1,400 additional premature deaths annually by the year 2030, as well as up to 120,000 new cases of exacerbated asthma.

But what if Trump simply repealed the Clean Power Plan, and didn’t replace it? The EPA’s proposal tells us. In the table below, it’s the first column: “No CPP.” The other three columns show the estimated annual health impacts of replacing the CPP with the ACE Rule, using three different scenarios—the middle one being the most likely.

In several cases, the estimated “morbidity effects” in the “No CPP” column are better than those in the column featuring the most likely scenario under the ACE Rule. In other words, by the year 2030, the EPA estimates that its own rule could cause more annual hospital admissions for respiratory problems, more emergency room visits for asthma, more exacerbated asthma cases, and more “minor-restricted activity days” than from having no rule at all.
