I totally agree, that looks a failure of planning.
Tying this locally, there
was a push in the State House to change MassPort's charter to require it consider broader climate objectives in their planning. Basically this is about blocking MassPort in its planned expansion at Hanscom. That expansion would mainly enable more super-high-polluting private jets.
I don't know how effective that charter amendment would have been. But regardless, these Authorities are just creations of the State, and they're malleable. A lot of States's plans for transportation involves delegating a chunk of that planning to a quasi-independent Authority. If that system isn't giving us the results we want, we can change up to board, change their charters, add responsibilities, strip power, or close them all together.
