How Biden is reversing Trump's assault on the environment

The new president is focusing on seven key areas to reverse a legacy of environmental destruction and climate denialism

Faced with an unfolding climate crisis that is fueling more powerful storms, enormous wildfires and scorching heatwaves in the US, Donald Trump unapologetically set about dismantling policies to cut planet-heating emissions, mocked or ignored climate science, and threw open vast tracts of American land and water to fossil fuel development.

In all, about 100 Trump-era environmental policies are being targeted, although some may take several years to reverse. Here's how Biden is doing it.
