Energy Saving

Air travel

Flights are responsible for about 4-5% of all climate-relevant emissions in the world. (CO², water vapour and nitrogen oxides). From a climate perspective, trains are always a better option since aircraft emit significantly more carbon dioxide than trains. However, bear in mind that high-speed trains use lots of electricity and are not so environmentally-friendly if the electricity is produced in fossil-fuel plants. There is a lot to keep track of here. But simply being aware of this when planning your trips can make a big difference for the environment.
