Have to “run” to store? Ok, why not run to the store. Or walk! For longer trips, carpool or use public transportation. According to the American Public Transportation Association, public transportation uses about half the fuel consumed by cars, trucks and light SUVs. Cars account for 21 percent of the world’s global warming emissions. Walking and biking account for none!

If 2007 is the year in which you plan to buy a new car, consider opting for the most fuel-efficient vehicle you can afford, preferably a hybrid. Hybrid models range from the Toyota Prius, which starts at around $17,000 and gets around 51 miles to the gallon on the highway and 60 miles per gallon in the city, to the $60,000 Lexus GS 450h, which gets about 25 miles per gallon in the city and 28 miles per gallon on the highway.
