Proposed $2 Carbon Fee To Park At Logan

Just weeks after parking rates at Logan International Airport were stealthily raised by $1, Gov. Deval Patrick is proposing another $2 rate hike as part of his transportation overhaul bill.

The so-called "carbon fee," proposed on page 137 of Patrick's 141-page bill, would mean that a 20- or 30-minute trip to Logan could cost $6 alone to park. Three hours in a Logan garage would cost $18 and all-day parking in a garage would jump to $26.

State transportation secretary James Aloisi Jr. tells The Boston Globe the fee would help fund airport-related transit projects and encourage more people to take public transportation to the airport.

The proposal comes just over a year after the $15 billion Big Dig project, designed in part to make it easier to drive to the airport, was completed.
