Google Flights Adds Carbon Emission Estimates to Search

Carbon emissions on the same flight routes can vary, and Google on Wednesday added emission estimates to its flight search worldwide to inform travelers. For years, Google Flights, Kayak, and Skyscanner have let consumers filter their flight search results to find ones that may have lower than average emissions, given plane type and other factors. What's new is that Google is displaying specific carbon emissions and that the data is for "nearly every" itinerary. Where possible, Google will also show seat-specific carbon emissions. Seats in premium economy and first-class seats generally emit more emissions because they take up more space on a plane. Carbon estimates for flights are otherwise hard to find. KLM is one of the rare airlines to have shown carbon estimates to customers since 2008. Goog
