Answer just a few questions like this and you’ll be on your way to getting cooler and smarter about carbon.
We’re calling it 20/20/20: Choose from 20 ways to make planet-friendly changes in your home, on the go, and with what you eat and buy, and in 20 days, you’ll be on the path to 20 percent less carbon. It’s like your own personalized carbon Couch-to-5k. And just like the Couch-to-5K challenge can help people trim pounds, the 20/20/20 challenge can help you trim carbon. And there’s plenty of carbon to lose—our day-to-day activities are pumping too much carbon into the air and it’s having a dangerous effect on our climate.
Odds are you’re already pretty cool and smart when it comes to your everyday energy decisions. But even the most carbon-conscious consumers can find easy ways to help save the planet—and save a little dough while you’re at it.
Find out how you can do your part by taking our 20/20/20 challenge and get a FREE sticker.
We’ve done the homework for you. For two years, our team of scientists did research and crunched numbers to come up with the most effective ways for people like you and me to combat global warming every day—and they even help identify what things we shouldn’t worry about. The answers may surprise you.
Don’t sweat the small stuff. Learn whether your choice in light bulbs or your driving habits make a bigger difference. Just a few easy changes add up fast—and if 20 of your friends do it… or 20,000… or 200 million…then we’re talking serious impact.
You’ve only got your carbon to lose. Thanks for being so cool and smart!
Sincerely, ![]()
