Here are some simple ways to emit less carbon in your daily life.  You'll save money and maybe even get in shape.

• Turn off the lights (and tvs, and radios) in rooms you are not using.

• Turn off computers and laptops when not in use.

• Unplug electrical devices when not in use.

• Try opening the windows and doors instead of turning on the air conditioning.

• Keep doors and windows shut and curtains drawn to keep your house toasty warm.

• Hang your washing instead of using the clothes dryer.

• Turn down the temperature on your water heater.

• Bike, walk, rollerblade or skateboard to destinations close by -- you'll save money on gas and parking, and get fit while you're at it!

• Take public transport instead of your car -- train into the city and the Meadowlands, take a train next time you go to Philly, D.C., or Boston.
