Weight control and health tend to go hand in hand—and what’s true for our waistlines also holds true when it comes to the weight of the greenhouse gas carbon dioxide (CO2) and the health of the planet. Excess pounds of carbon dioxide are raising the earth’s temperature and putting coastlines, not waistlines, at risk. Yet for a lot of people, the idea of going on a carbon diet to reduce pounds, much less tons, of the stuff seems airy when there’s nothing to hold onto.

Think of pounds of CO2 as inflated balloons: One pound of CO2 would fill a balloon about two and a half feet wide, and the amount of energy each of us uses every day, just to power our homes and drive our cars, would fill 47 of them. Imagine that for each member of your family 47 of those balloons are added to your home each day. In a week, a family of four would pack in 1,316 balloons, in a month 5,703, and in a year 68,432—enough to fill a building nine stories tall and 100 feet on each side. You wouldn’t be able to find your house in it. It’s no wonder we’re smothering our planet in greenhouse gases. The more balloons of CO2 in the air, the more heat they trap in our atmosphere. So here’s a 10-step carbon diet—a program to keep the greenhouse gas out of 142 balloons every week.

1. Wash your clothes in cold water instead of hot.

Start with something easy. Washing machines produce over 500 pounds of CO2 a year when run on hot water. But your clothes will be just as clean and may even last longer when laundered in cold water.

2. Use a drying rack.

Dryers produce about 1,450 pounds of CO2 per year and the high heat damages fabric. So get more life out of your garments, lower your electric bill and spare the planet by drying at least half of your clothes on a rack or line. Plus, sunlight is the most effective stain-remover around.

3. Seal and weatherstrip your home.

This summer, sealing your home will ensure you don’t lose the cool air you’re paying for. Caulking and weatherstrip- ping doors, windows and any cracks or openings in walls will save about 225 pounds of CO2 per season to run your AC. It pays off even more in the winter when you need to trap the heat; every year, you save 640 pounds of CO2 if you have natural gas heat and 470 pounds if you have elec- tric heat. And it’s a simple job.

4. Insulate.

Insulating your home is a bit more demanding and best handled professionally. There are a number of insulating options better than fiberglass, which presents a breath- ing hazard from airborne glass particles and formalde- hyde released during installation. Some green-building specialists claim that spray foam insulation is the most efficient and cost-effective variety, even though it’s usu- ally composed of petroleum-based polyurethane. If you choose spray foam, consider a blend that includes soy- bean oil, such as BioBase501, to reduce the reliance on fossil fuels. Another alternative, recycled denim insula- tion, uses a more eco-friendly material but isn’ t as effi- cient an insulator as polyurethane foam.
