The EPA administrator says he is rolling back dozens of environmental rules, including those crucial to California programs on climate change and electric vehicles, and closing offices that worked to lower pollution in poor communities.

EPA Administrator Lee Zeldin said he is rolling back 31 environmental rules, including a scientific finding that has long been the central basis for US action against climate change.

Three former Environmental Protection Agency leaders say rollbacks proposed by the Trump administration endanger the lives of millions of Americans and abandon the agency's mission to protect the environment and human health.
