Is the future of air travel truly sustainable, or are we just greenwashing our way to more emissions? The aviation industry accounts for about 2.5% of global CO2 emissions, and while sustainable aviation fuels sound promising, they represent less than 0.1% of current fuel use. I've flown for years and noticed that few airlines are transparent about their carbon offset programs—some even double-count the same offsets. Given that passenger numbers are projected to double by 2040, can we realistically cut emissions without drastically reducing flights, or will technological breakthroughs save us?
