A comparison of carbon emissions from trains, cars and airplanes

Do I necessarily have to spend my holidays abroad and go by airplane for this year's vacation? When was the last time I went on vacation by bus or train?

More and more of us are asking these questions. Especially in times of a global pandemic. But also beyond the corona pandemic, we all have to take responsibility for our actions in the face of the global climate crisis. This also includes responsibility for our personal carbon emissions from travel activities.

Many travel destinations can be easily reached by bus or train. A train journey with around 30-40 g CO2-equivalents (CO2e) per person-kilometer is the most climate friendly means of transportation.

By way of comparison: on average, a flight causes around ten times as much carbon emissions, and a car emits around five times as much carbon per person-kilometer.
