A clear way to fly on less CO₂
With the Least CO₂ sorter, you can immediately see how flights stack up environmentally. It shows the average amount of CO₂ and non-CO₂ emissions for all flight routes in your search result, plus how much each individual flight emits and how those compare to the average.
We’ve included more transport alternatives to our flight search engine, so in routes where trains and buses are also available, these options will appear in your search results. We also added campervan and ferry options to give you even more ways to get more places on less CO₂.
