The Subway restaurant chain will reduce its greenhouse gas emissions nationwide by an estimated 3 million pounds, simply by replacing one incandescent light bulb with a more efficient compact fluorescent bulb in each of 22,000 stores.
The largest franchise chain in the U.S. will participate in the Environmental Protection Agency’s (EPA) Energy Star Change a Light, Change the World campaign on October 1.
By replacing just one bulb with a Philips, energy efficient, compact fluorescent light (CFL) bulb, each restaurant will reduce its annual energy consumption by 87.6 Kilowatt hours. Together, the 22,000 restaurants will save 1,927,200 kilowatt hours–which is equivalent to removing more than 275 cars from the road for one year.
Subway will also encourage Americans to take the Energy Star Pledge to Change a Light/Change the World. The Pledge will be available on the subway.com and subwayfreshbuzz.com web sites.
Subway said it is also evaluating other ways to make their restaurants more environmentally friendly.
The first Subway Eco-Store opened last year in Kissimmee, Forida. Since then, four more have opened and there are more in various stages of planning, the company said. The brand is working with the U.S. Green Building Council to earn Leadership in Energy and Environmental Design (LEED) certification for the Eco-Stores.
Other initiatives include the relocation of several redistribution centers to save fuel, and changes in packaging and cutlery and napkins.
