Up To 17 Cents A Gallon — New Carbon Emissions Tax Would Add $$ To Gasoline Prices

The pact being developed by Massachusetts and other East Coast states to cap carbon emissions from vehicles could add up to 17 cents to the price of a gallon of gas, according to the newest estimates, but could also generate more than $500 million in revenue for state government in Massachusetts.
Leaders from a coalition of eastern states, including Massachusetts, have been working for over a year to develop a regional "cap-and-invest" program to reduce carbon pollution from cars and trucks and generate the resources needed to expand clean transit options and improve public health.
