Trump administration sues California over cap-and-trade agreement with Canada

Trump administration took aim Wednesday at one of California’s premier climate change policies, suing the state for entering into a cap-and-trade agreement with the Canadian province of Quebec to lower fossil fuel emissions.

The lawsuit filed by the Department of Justice argues that California overstepped its legal authority by forging an agreement with another country designed to limit air pollution and climate-warming greenhouse gases. Only the federal government has this power, according to the suit, which also names the state’s top air quality regulator and the Western Climate Initiative, a nonprofit group California and neighboring states created to promote similar policies.
