Frequent travelers who want to better understand — and act upon — their carbon footprint now have a new tool in their toolkit, thanks to TripIt from Concur.

In its latest update, TripIt shows a flight’s carbon emissions and provides practical ideas on how to reduce or offset its environmental impact.

“Our goal is to help you better understand the environmental impact of all of your flights,” said Jen Moyse, director of Product for TripIt. “That’s why we made it easy for you to see, track, and offset your carbon footprint.”

TripIt is the first travel organizing app to automatically aggregate flight emissions across providers, post-booking, giving you a holistic view of your air travel footprint. The feature will be available to all TripIt users, both free and Pro.

How Does TripIt Work?

TripIt now shows you the carbon emissions for your flights, tracks your annual flight emissions, and gives you ways to offset that environmental impact — right alongside all your travel plans. With the new Carbon Footprint feature, you can:

  • See your flight’s carbon emissions
  • Track your annual carbon footprint for air travel
  • Offset and reduce your environmental impact, with practical suggestions right in the app

How Is It Calculated?

TripIt calculates your carbon footprint using the Greenhouse Gas Protocol, the same methodology used by American and European government agencies. The app takes into account factors like distance, flight class, and environmental elements.
