Thanks for re-iterating this. Granted, due to where the emissions take place, air travel is slightly stronger/higher but I feel like the sole focus on air travel is an annoying feature of a lot of climate-change discussions. It's something we really don't have many technically or economically viable alternatives for yet. Why don't climate-change measures and discussions focus on the other 95%+ of sources that are easier to address?
