In a rapidly warming world, I don't see the need to spend all that energy on supersonic transport when Zoom will do just fine. There are sustainable fuels, but they use a ton of energy. It's an extravagance the world cannot afford.
- boulos 5y agoPeople definitely shouldn't fly if they don't need to, but I think you're overestimating the warming effect from aviation. Estimates put it in the ~3% range overall [1]. Most of that (80%) was passenger travel [2] (pre-pandemic) and 20% cargo. The EU's push for short-haul flight bans [3] makes a lot of sense though, especially when high-speed (and sometimes electrified) rail is an option.
