Cutting down is easier than you might think
Reducing your family's transportation CO2 emissions is easier than you might think. The best way to cut down is to just skip the car when possible — walking or biking is better for you and the planet. In addition, try to combine your errands into a single trip to save time, gas and CO2 emissions. If you're lucky to live in a place with good public transportation, use it, and enjoy the time you'll have to read a book or have a heart-to-heart with your kids.

But even when you have to drive, there are things you can do to get better gas mileage — and reduce your contribution to global warming. Scheduled maintenance keeps your car running at its best. Tire pressure is particularly important — keeping them at the recommended pressure (see the sticker in the driver's door frame or on your gas cap lid) can save up to 4 percent on your gasoline bill. Less gas burned equals less CO2 produced.

When it comes time to trade up to your next set of wheels, consider your needs carefully. Are you currently driving a bigger vehicle than you need? If you're in the market for a new car, be sure to check out the new car-based "crossover" SUVs that get better mileage than their truck-based competitors. Hybrids and the new batch of clean diesels coming soon are also a good bet. But do the math first; the price premium you pay for a hybrid or diesel won't necessarily translate into lower costs over the long run. You might be better off with a more conventional, less expensive car that gets good, if not great, mileage.
