Arlington is launching a ‘Retail Doors Campaign’ as part of its ongoing Green Games business sustainability competition. The campaign encourages individual shops and restaurants to save energy by closing their doors.

“The Campaign is a voluntary effort through which retailers pledge to keep their doors closed if the air conditioning or heat is running,” said county spokeswoman Shannon Whalen McDaniel. “Arlington is asking retailers to make this commitment to close their doors, which will help save them money, reduce greenhouse gas emissions, and create a more comfortable indoor environment for staff and customers.”

It’s “a win-win situation all around,” Whalen McDaniel said.

Businesses that want to join the campaign can sign up on the Arlington Green Games website.
