Travel

Airplanes in flight release a lot of carbon dioxide. A round-trip flight from New York to San Francisco emits a staggering two metric tons. Most of these emissions occur during takeoff and landing. If you’re flying from here to there, choose the most direct route possible. Nonstop flights can sometimes cost a little more than connecting flights, but the tradeoff is that you’ll save time and ensure a more comfortable travel experience, in addition to helping the environment.
