New Hampshire Gov. Chris Sununu is reportedly saying his state will not join the U.S. Climate Alliance, a coalition of states pledging to uphold the Paris climate agreement despite President Trump's decision to back out.
Gov. Sununu told the Concord Monitor he did not want to join the 12-state pact because of concerns about the alliance's impact on the economy and the environment.
Massachusetts Gov. Charlie Baker became the first Republican governor to bring his state into the alliance on June 2.
"Our administration looks forward to continued, bipartisan collaboration with other states to protect the environment," said Gov. Baker in a statement.
Vermont's Republican Gov. Phil Scott also signed on to the agreement.
There are currently 12 states committed to the alliance, which aims to cut carbon emissions by 26 percent from 2005 levels.
