Finnair has launched an emissions calculator that's the first to use actual real world data to drive it's predictions rather than estimates or assumptions.
When queried, their calculator looks at the actual emissions numbers for Finnair's fleet from the quarter of the year before to make its calculation. Finnair updates those numbers four times a year, making their calculator the most precise and up to date flight emissions engine on the web.
Just punch in the cities you are traveling between and up pops the raw numbers of your environmental impact.
