Researchers at the Chalmers University of Technology and the University of Gothenburg (Sweden) have developed a tool that calculates how much climate impact your holiday has, depending on your transportation mode and what type of accommodation you'll choose. The website also gives tips on sustainable tourism. I chose a trip that I tend to do yearly to visit home and the difference between plane and train is quite striking. If I wasn't travelling alone and using a car that could be a good option as well. I find the calculator very interesting and I would love it to be more user friendly and appealing! https://travelandclimate.org/tourism-sustainability
