“The EPA’s rescission proposal is not just a step backward — it is a dangerous retreat from science and the law,” said Attorney General Bonta. “To suggest that greenhouse gas emissions don’t endanger public health is absolutely reckless. Not only does EPA’s proposed rescission ignore those facts, which are backed by robust climate science, but it also violates EPA’s legal obligations under the federal Clean Air Act to regulate greenhouse gas emissions to address climate change. Attorney General Bonta co-led this letter alongside attorneys general of Connecticut, Massachusetts and New York. A robust regulatory program for greenhouse gas emissions is also crucial to vehicle affordability, consumer choice, and the success of the American automotive industry.
