A climate bill with fossil fuel victories

Fossil fuels — coal, oil and natural gas, primarily — remain the dominant energy sources for much of the world, with their accompanying infrastructure of mines, drilling and production wells, pipelines and various forms of transportation. But they have become more problematic as governments struggle to address climate change and pivot to energy sources that do not result in carbon dioxide emissions.

More than 30 years after the last major update of the Clean Air Act, the U.S. Supreme Court has upended the ability of Congress to give the Environmental Protection Agency and other federal agencies broad scope to combat air pollution, including the emission of greenhouse gases. Meanwhile, further Biden administration efforts to limit emissions face opposition in the courts.
