Six Ways to Travel Green:

1. Travel less and stay longer rather than taking several short trips.

2. Take trains when you can instead of flying or driving.

3. Taking nonstop flights rather than connecting flights.

4. Reuse towels and sheets in hotel rooms rather than getting them changed every day.

5. Use local public transportation instead of renting a car.

6. Travel domestically rather than internationally.
