Connecticut became one of the early states to rebuke President Trump’s disavowal of the Paris climate accord with a decision Friday by Gov. Dannel P. Malloy to join a fast-growing coalition of states, cities, businesses and universities intent on ensuring the U.S. still acts to reduce greenhouse gases.

Malloy, the chairman of the Democratic Governors Association, joins the Democratic governors of California, New York and Washington state in the United States Climate Alliance, a group quickly organized Thursday by former New York Mayor Michael Bloomberg and others in the wake of Trump’s announcement the U.S. would stand apart from the world’s nations on the issue of climate change.

The decision was an easy one for a governor in Connecticut, a state with a long history of bipartisan support of efforts to reduce greenhouse gases.
