If everyone in the U.S. said “no thanks” to ATM receipts, it would save a roll of paper so long it could circle the equator fifteen times.
Change light bulbs from traditional incandescent to compact fluorescent. If every American did, it would reduce greenhouse gases equivalent to the emissions of nearly 800,000 cars.
Turn off the car instead of idling when waiting to pick up the kids at school. When a car idles for more than 30 seconds it actually uses more gas and releases more greenhouse pollution into the air then if it were turned off.
If every household in the U.S. replaced just one roll of virgin fiber paper towels (70 sheets) with 100% recycled ones we would save 544,000 trees.
