![]() ![]() The basis for calculating emissions per vehicle kilometre for different fuel and vehicle types follows below: ![]() The quantity of emissions per person will depend on how many people travel together in the car, which you enter yourself when using the calculator. According to our calculations it is causing emissions of 137 grams of CO2 per vehicle kilometre, which is based on data in a report from the Swedish Energy Agency. We have taken the most common combination in Sweden as the default choice, which is a medium-sized diesel car. In the calculator, you can choose between 4 different sizes of the car and 9 different fuels. If you know that a leg of your trip is operated by diesel train, you can change the type of train in the calculator to “Train Diesel” for a more accurate calculation. Non-electrified tracks are mostly used for local trains and infrastructure maintenance. This is partly because the level of electrification in Europe is relatively high (80%) and the level is also rising. Some trains in Europe run on diesel, but we have nevertheless chosen to have “Electric trains Europe” as the default outside the Nordic countries. For diesel trains, emissions are estimated to be 91 grams of CO2 per passenger kilometre, regardless of the country. We have estimated that train travel in the Nordic countries (except Denmark) causes 7 grams of CO2 per passenger kilometre (Electric train Nordic countries) and that an electric train in Europe and Denmark (Electric train Europe) causes 24 grams. Read more about why in the Methodology Report. ![]() In our calculations, we do not take into account the fact that some rail companies use eco-labelled electricity. This is because emissions from electricity production differ from country to country. There is also a difference between an electric train operated in the Nordic countries or in Europe. Emissions from individual trips vary according to the energy consumption of the specific train and its occupancy rate. The calculation of the climate footprint of trains is an average for trips by electric train. The full scientific underpinnings for these calculations can be found in our Methodology Report. At the bottom of the page is a table showing the emissions for all different modes of transport we use in the calculator. This section contains general information on how we have calculated the emissions from travel by train, car, bus, flight and ferry. ![]()
