General Motors Co.’s Chevrolet division is working with the Maine State Housing Authority to insulate 5,500 low-income homes in the state.

The program is Chevrolet’s first investment from a $40 million multi-year commitment to prevent 8 million metric tons of carbon dioxide from being released.

The homes will be weatherized with blown-in recycled-content insulation, tight-fitting attic hatches, sealed chimneys and furnace tuneups.

Maine was recommended for help by Clean Air-Cool Planet, a regional nonprofit with offices in Portsmouth, N.H.
