Subway has upped its commitment to sustainability. As a part of the restaurant chain's ongoing goal to make its restaurants and operations more socially responsible, the company has made LED lighting the standard for all new and remodeled restaurants. The upgrade will provide energy-efficient lighting that, in 2014 with a small percentage of stores participating, saved 21.9 million kilowatt hours – enough energy to power 1,996 households in a single year.
