A bill requiring Rhode Island to get to net-zero carbon emissions by 2050 won final approval Tuesday in the General Assembly and is headed to Gov. Dan McKee for his signature.

McKee previously expressed concern that the Act on Climate might cause excessive and costly litigation. But Attorney General Peter Neronha dismissed that concern in a letter to McKee, and the governor’s communications director, Andrea Palagi, said he looks forward to signing the bill.

“As the governor has said, he strongly supports the environmental goals of the bill regarding the reduction of greenhouse gas emissions,” Palagi said in a statement. “As part of his due diligence, the governor requested a letter from the attorney general which addressed his concerns regarding the litigation portion of the legislation. The Governor thanks the attorney general for the letter and his quick response.

In a final vote on each other chamber’s version of the bill, the House approved the Act on Climate with no debate, 51-21, and the Senate voted in favor, 28-9.

Senate Republican lawmakers renewed some of the arguments previously made by their House colleagues, citing concerns about the potential cost of implementing the legislation and how future regulations will be drawn up by unelected state bureaucrats, rather than state lawmakers.

“We can’t possibly achieve 80 percent emissions below 1990 with de-carbonizing and retrofitting our homes at tremendous cost,” said Sen. Jessica de la Cruz (R-North Smithfield), citing one of the requirements along the way to net zero. “It is our responsibility to speak for our constituents. We are their voices when it comes to making laws.”

Efforts to change the legislation through a series of amendments were voted down by large margins.

Sen. Dawn Euer, the Senate sponsor of the Act on Climate, predicted the measure will be good for Rhode Island and its citizens.

“Act on Climate will send a signal to clean energy companies, investors, as well as the federal government that Rhode Island is ready to lead in the green economy,” Euer said. “By adopting this legislation, we will be creating the conditions to attract investments, federal dollars and new businesses at the forefront of the energy transition.”
