A spokesman for Rhode Island Gov. Don Carcieri said Rhode Island, Massachusetts and Connecticut had misgivings over the proposed nine-state plan to cut so-called greenhouse gases that contribute to global warming.

Carcieri is concerned about the costs, according to spokesman Jeff Neal. “Ultimately we don’t know how much this plan will raise energy prices,” Neal said.

A spokeswoman for Massachusetts Gov. Mitt Romney said he would likely comment on the matter on Thursday. Romney has expressed concerns with the initiative in the past, saying the costs of cutting emissions would be passed on to consumers.
