Despite Massachusetts Gov. Charlie Baker leading the charge for a 5 percent annual carbon cap, the administration of Maryland Gov. Larry Hogan, a fellow Republican, said Maryland may leave RGGI if the cap is strengthened. This would be a mistake, potentially slowing the state's job growth and economy. That's why I'm calling on Governor Hogan to reverse course and embrace, along with the other RGGI governors, the 5 percent annual pollution cap while creating a plan to guarantee net economic and environmental benefits from RGGI for underserved communities.
