Getting, say, a million people to escape velocity would not be significant in terms of greenhouse emissions, compared to the ~8 trillion revenue passenger kilometres flown annually (which itself is a tiny fraction of global emissions).
Also, if you assume that those colonists are not coming back, their exodus is likely to be carbon negative for Earth.
- bsmith 7y agoExcellent points. I want to follow up with some back-of-the-envelope math on this later, if I have time. My intuition was that it takes a whole heck of a lot of fuel to get someone to even LEO velocity. Would love to see how that corresponds with air travel.
