I wish we could decarbonize long distance travel. I would love to see more of the world but I can't justify contributing to climate change for such a trivial thing. I can limit emissions by doing smaller trips with bike, bus or train locally, but oceans present a problem.
A round trip transatlantic flight from New York to Berlin emits 2.4 metric tons of CO2e per person.
The UN says global emissions per capita needs to drop to 1.5 metric tons/year by 2050 if we have any hope of keeping to a 2C temperature rise this century.
I wonder if there's any hope of electric planes hitting the energy density needed for commercial airlines, or algae based plane fuel taking off. I would even use a slower or more expensive mean of travel if it meant the emissions were drastically reduced.
