Find flights with lower carbon emissions

A video showing how Google's travel tools can help you find more sustainable hotel or flight options.

Last month, we shared new sustainability initiatives from our travel team, including ways you can find eco-certified hotels on Google. Now, we’re bringing information on carbon emissions directly into Google Flights.

Beginning today, you’ll see a carbon emissions estimate for nearly every flight in the search results — right next to the price and duration of the flight. So when you’re choosing among flights of similar cost or timing, you can also factor carbon emissions into your decision.

Google Flights shows estimated carbon emissions in the search results.

These emissions estimates are flight-specific as well as seat-specific. For instance, newer aircraft are generally less polluting than older aircraft, and emissions increase for premium economy and first-class seats because they take up more space and account for a larger share of total emissions. 

To put these estimates in context, flights with significantly lower emissions will be labeled with a green badge. And if you want to prioritize carbon impact, you can sort all of the results to bring the greenest flights to the top of the list.

You can sort results by carbon emissions and see how each flight compares to the average.

To produce these estimates, we’re combining data from the European Environmental Agency with the flight-specific information we get from airlines and other providers such as aircraft type, trip distance and the number of seats in each seating class. To learn more on how we estimate emissions, visit our Help Center.

It’s critical that people can find consistent and accurate carbon emissions estimates no matter where they want to research or book their trip. That’s why we recently joined the Travalyst coalition, where we’ll help develop an open model for calculating carbon emissions from air travel and promote standardization across the travel industry using this framework.

This update to Google Flights is just one of the many ways we’re helping people make sustainable choices in their everyday lives. Read the latest in this post from Sundar Pichai.
