Twenty-five cities, counties and states are suing the Environmental Protection Agency for erasing the majority of limits on greenhouse gas emissions from power plants, Robyn Griggs Lawrence writes for Smart Cities Dive. The coalition also intends to sue the EPA for not regulating emissions from gas-fired power plants.

Smart Cities Dive reports:

“The president’s actions won’t unleash American energy, but they will lead to record profits for polluters — all while our air gets dirtier and our bills stay just as high,” Denver Mayor Mike Johnston said in a statement. “The cost of these rollbacks is our health, and we look forward to fighting this in court and seeing these commonsense regulations restored.” 

Denver, Chicago and New York City are the suing cities. States in the coalition include California, Massachusetts and Hawaii. The District of Columbia is also a part of the coalition.
