Carbon dioxide reduction (for two loads a week): up to 500 pounds a year.
Turn down your water heater thermostat; 120 degrees is usually hot enough.
Carbon dioxide reduction (for each 10- degree adjustment): 500 pounds a year.
--------------------------------------------------------------------------------
HOME HEATING AND COOLING
Don't overheat or overcool rooms. Adjust your thermostat (lower in winter, higher in summer).
Carbon dioxide reduction (for each 2-degree adjustment): about 500 pounds a year.
Clean or replace air filters as recommended. Cleaning a dirty air conditioner filter can save 5% of the energy used.
Carbon dioxide reduction: About 175 pounds a year.
--------------------------------------------------------------------------------

Buy energy-efficient compact fluorescent bulbs for your most-used lights.
Carbon dioxide reduction (by replacing one frequently used bulb): about 500 pounds a year.
Wrap your water heater in an insulating jacket.
Carbon dioxide reduction: Up to 1000 pounds a year.
Install low-flow shower heads to use less hot water.
Carbon dioxide reduction: Up to 300 pounds a year.
Caulk and weatherstrip around doors and windows to plug air leaks.
Carbon dioxide reduction: Up to 1000 pounds a year.
Ask your utility company for a home energy audit to find out where your home is poorly insulated or energy-inefficient.
Carbon dioxide reduction: Potentially, thousands of pounds a year.
--------------------------------------------------------------------------------
GETTING AROUND
Whenever possible, walk, bike, carpool or use mass transit.
Carbon dioxide reduction (for every gallon of gasoline you save): 20 pounds.
When you buy a car, choose one that gets good gas mileage.

--------------------------------------------------------------------------------
REDUCE, REUSE, RECYCLE
Reduce waste: Buy minimally packaged goods; choose reusable products over disposable ones; recycle.
Carbon dioxide reduction (if you cut down your garbage by 25%): 1000 pounds a year.
If your car has an air conditioner, make sure its coolant is recycled whenever you have it serviced.
Equivalent carbon dioxide reduction: Thousands of pounds.
--------------------------------------------------------------------------------

Insulate your walls and ceilings; this can save about 25% of home heating bills.
Carbon dioxide reduction: Up to 2000 pounds a year.
If you need to replace your windows, install the best energy-saving models.
Carbon dioxide reduction: Up to 10,000 pounds a year.
Plant trees next to your home and paint your home a light color if you live in a warm climate, or a dark color in a cold climate.
Carbon dioxide reduction: About 5000 pounds a year.
As you replace home appliances, select the most energy-efficient models.
Carbon dioxide reduction (if you replace your old refrigerator with an efficient model): 3000 pounds a year.

SCHOOLS, BUSINESS, AND COMMUNITIES
Reduce waste and promote energy-efficient measures at your school or workplace. Work in your community to set up recycling programs.
Carbon dioxide reduction (for every pound of office paper recycled): 4 pounds.
Be informed about environmental issues. Keep track of candidates' voting records and write or call to express concerns.
Carbon dioxide reduction (if we vote to raise U.S. auto fuel efficiency): Billions of pounds.
