The Maine Board of Environmental Protection voted 4-2 against adopting a mandate to significantly increase electric and hybrid vehicle sales in the state by 2032. This decision came on the same day the Biden administration introduced the strictest-ever limits on tailpipe pollution. The proposed state standards aimed to raise the share of electric and hybrid vehicles sold in Maine to 51% by 2028 and 82% by 2032, from about 6% in the previous year. The board’s chair suggested that such a significant change should be decided by lawmakers, highlighting the complexity of the issue and existing uncertainties​​.
