Maine is moving to have several possible climate bills this session. During the past eight years with Republican Governor Paul LePage, there was little chance for passage. But newly elected Democratic Governor Janet Mills is signaling that climate policy will be a priority for her administration.

Maine is already a member of the Regional Greenhouse Gas Initiative (RGGI) so has cap and trade control on power plant emissions. They are also a member of the Transportation and Climate Initiative, but have not joined a select group of TCI states who are working to cap transportation emissions and trade emission permits in a system modeled after RGGI.

2019 Legislative Session

A carbon tax/fee bill (LD 434) was proposed by Rep. Deane Rykerson, with a host of co-sponsors. According to the bill, a fee would start at $5 per metric ton of carbon during the fiscal year 2020-21 and increase by $5 per each fiscal year from 2021-22 to 2027-28, remaining at $40 per metric ton each fiscal year after.
