Ridgefield has joined Sustainable Connecticut, a voluntary alliance of towns committed to  sustainability practices ranging from renewable energy and water conservation to housing diversity and shopping local.

“Sustainable CT communities strive to be thriving, resilient, collaborative and forward looking,” reads a resolution approved by the Board of Selectmen.

The selectmen passed the resolution Thursday, Feb. 8, making Ridgefield among 20 Connecticut municipalities committed to the program.

Ridgefield joined at the request of Ben Oko of the Ridgefield Action Committee for the Environment, which will function as the town’s “advisory sustainability team.”

The program offers points toward certification at three levels for actions taken to advance sustainability in nine categories, ranging from “well stewarded land and natural resources” to “efficient physical infrastructure and operations” to “dynamic and resilient planning” to “thriving local economies.”

The “clean and diverse transportation systems and choices” category lists five recommended goals. That list ranges from “promote effective parking management” to “encourage smart commuting” to “support zero emission vehicle deployment” — with differing point totals available for each.

“What do these points get you?” asked Selectman Bob Hebert.

“It helps you with grants,” First Selectman Rudy Marconi said.
