"A panel of federal appeals judges Washington, D.C., on Monday nixed a Trump administration rule that would have prevented the Environmental Protection Agency (EPA) from setting greenhouse gas limits on multiple polluting industries.
The rule, finalized just before President Trump left office, only allows greenhouse gas limits on power plants, exempting activities like such as oil and gas production and iron and steel manufacturing.
The regulation says that only sectors whose pollution makes up more than 3 percent of the country’s greenhouse gas emissions are “considered to contribute significantly to dangerous air pollution.”"
