Fewer cars on the road mean less carbon emissions, cleaner air and a reduced dependence on oil. Taking the bus or train or sharing a ride with a friend just once or twice a week can make a big difference.

Consider an electric vehicle. EV drivers decrease their carbon footprint by commuting with zero emissions and can have an even greater environmental impact by charging with 100% clean energy. And if you’re still driving with traditional fuel sources, consider purchasing carbon offsets to offset your commute.

Improve your car’s fuel efficiency by keeping your tires at the right pressure level and getting regularly scheduled maintenance like inspections and oil changes.

Airplanes create more pollution than automobiles typically do. Before you book that flight, ask yourself if a videoconference or virtual meeting will suffice. If you do have to fly, choose nonstop flights whenever possible and pack light to help reduce CO₂ emissions.

When staying in a hotel, energy conservation still matters. Pretend you’re at home and turn off the lights, television and A/C whenever you leave the room for an extended period of time.

If you’re going a relatively short distance, make it a zero-carbon trip by walking or riding your bike. Added benefit: You’ll burn a few calories along the way.
