"I think the industry knows that this is the direction that things are heading," says Hannah Pingree, co-chair of Maine's Climate Council.

She says that hydrofluorocarbons, or HFCs, are a more potent global warming gas than carbon dioxide. And she says the federal Environmental Protection Agency had been planning to take action against them.

"Essentially that regulation was vacated by the current administration, and so that's where states are now starting to figure out how to put rules into effect that are very similar, so that we don't start to lose significant ground."

Pingree says the phase-out would go into effect as alternative, less-damaging coolants are brought to market. If the legislation passes, she says, most products containing HFCs would be barred from sale in Maine beginning in 2021.

The three New England governors are joining 16 others around the country to propose new rules that would require the HFC phaseout.
