Compact Fluorescent Lights (CFL’s) last up to 10x longer than traditional bulbs and use only a fraction of the energy, saving you $30-$50 over their lifespan. And LEDs save even more! Rally Your Road Crew. Carpool and help relieve congestion on your daily ride to work. Did you know that Americans waste 2.3 billion gallons of gas every year while stuck in traffic. Turn off your engine and don’t idle if in stopped traffic! Pump Up. Pump Less. Properly inflated tires can improve your gas mileage enough to earn you a free tank of gas every year. Ride public transit and help conserve and estimated 1.4 billion gallons of gas and curb the release of roughly 1.5 million tons of harmful CO2 a year. Buy carbon offsets to help counteract the CO2 pollution from you next big trip. The U.S. alone wastes over $1 billion a year on computer monitors that are turned on when they shouldn’t be. Lower the CO2 emissions of your appliances and electronics by up to 50% by buying the most efficient ones available. Bag For Life. Cut the amount of plastic bags you use when shopping by reusing bags of using a fabric shopper or ‘bag for life’. Using fewer bag preserves resources needed to manufacture plastic bags. Low Carbon Diet. Eat vegetarian foods as much as possible. Meat makes less efficient use of land, soil, water, and energy – and cows emit 300 liters of methane per day. And buy locally produced foods as much as possible.
