It's true that a single private jet is causing tons of CO2 emissions. But in the end, all consumers control the market. You can jump one link further in the chain to regions with much lower emissions. Somalia/Congo emit over 200x less CO2 per capita in comparison to the US. Do you think that's fair for them if the "regular salaried people" don't care? If responsibility always gets dismissed by pointing to someone emitting more, nothing changes.
