Using flight search tools with accurate emission models.

The type of plane can make a significant difference on the emissions impact of your travel.  Explore that impact in this scenario and learn what to look for when searching for your next flight.

Avoid flying on regional jets

Aircraft Crowding

Why getting on crowded flights is good.

The number of people on a flight impacts the per passenger efficiency of a flight.  Explore the magnitude of that impact in the following scenario.

Aircraft vs Vehicles

Get an intuition for when you should drive and when you should fly.

Sometimes you can lower the emissions of travel by driving a particular travel leg instead of flying.  Other times flying can get you to your destination with lower impact.  We’ve created two scenarios to illustrate both of these extremes.  You can use our exploration tool to understand your own more nuanced scenarios.
