Cut your carbon footprint by biking or walking to work, or when you're doing errands in your neighborhood. Start out by doing it once a week on a nice, not-too-hot day. Then commit to two or three days a week. Or make a pact to bike during the best season where you live. If you're in a warm climate, it might be more enjoyable to bike during the fall or winter months. The reverse holds true for those living in cooler climates.
But not everyone can walk or bike to work. You mightlive too far away from the office or it just isn't safe enough, If that's the case, then look into public transportation or car pooling. You'll still reduce your carbon footprint.
