The unmentioned impact of traffic congestion

ESSICA RINALDI/GLOBE STAFF
Bumper-to-bumper traffic on I-93 is just one of the transportation issues faced daily in the state.

I agree that traffic congestion and unreliable MBTA service are serious problems. And Chris Dempsey is right: We need a lot of different steps in raising the revenue required for addressing the huge transportation problems in Massachusetts.

But your article (“No fixes in sight for Mass. commuters,” Page A1, May 16) fails to mention climate change, which is the elephant in the room. A single-person car emits nine times the greenhouse gases emitted by a fully-loaded Red Line train.
