Tourism is part of the problem. The tourism sector generates around one-tenth of the greenhouse gas emissions that are driving the climate crisis.
What is a carbon passport?
The idea of a carbon passport centers on each traveler being assigned a yearly carbon allowance that they cannot exceed. These allowances can then “ration” travel.
Globally, the average annual carbon footprint of a person is closer to 4 tons. But, to have the best chance of preventing temperature rise from overshooting 2 Celsius, the average global carbon footprint needs to drop to under two tons by 2050. This figure equates to around two roundtrip flights between London and New York.
Intrepid Travel’s report predicts that we will see carbon passports in action by 2040. However, several laws and restrictions have been put in place over the past year that suggest our travel habits may already be on the verge of change.
