The controversial regional effort to reduce vehicle emissions and boost transit funding along the East Coast appears to have dwindled, at least for the time being, to include just Massachusetts, Rhode Island and Washington, D.C. as active participants.
The program would set a limit on vehicle emissions, and hold auctions for fuel suppliers that transport gasoline into Massachusetts and other states to purchase allowances for every ton of carbon dioxide that the fuel they are carrying would emit when burned.
It’s not clear all Gov. Charlie Baker’s fellow governors are on board with his regional approach to taxing cars’ carbon emissions, putting a big chunk of future transportation funding in doubt.
