President Trump has repealed Obama-era regulations pertaining to power plants. As a result, 22 Democrat-led states are suing the Trump administration.

According to The Hill:

Attorneys general from 22 states and several major cities including New York City and Los Angeles argue that the Trump administration’s rule violates the Clean Air Act by having virtually no impact on carbon emissions.

The Environmental Protection Agency (EPA) had finalized the rule in June to repeal and replace a capstone Obama-era carbon pollution regulation they say exceeded agency authority.

The new replacement rule to the Clean Power Plan (CPP), deemed the Affordable Clean Energy (ACE) rule, aims to give states more time and authority to decide how to implement the best new technology to ease net emissions from coal-fired plants.

“Besides ignoring the science of climate change – the text of the ACE rule barely mentions climate change, much less recognize[s] the dire threat it poses to people’s health, the economy, and the environment – the rule disregards requirements of the federal Clean Air Act,” which requires regulators to use the “best system of emission reduction,” New York Attorney General Letitia James (D) said in a press release.

The action by the Trump administration has faced lots of pushback as this is already the second lawsuit filed against the action.
