If you're profiting from foisting negative externalities onto others, but assuming that 'everything will be fine', then what happens is that after the data is collated, you recompense the damage done. It's not perfect, but it works. If you're playing softball in the neighborhood, and accidentally smash a neighbor's window, you pay for the window. You know you could have, you took the risk, and it happened.
Externalities from AGW are currently assumed to be about $50 USD per tonne. A lump-sum transfer to those damaged by AGW (for all of your emissions since 1997, even in the future) would absolve someone for current dismissal of the threat. It's why I had to start taking the threat seriously, early, because I cannot live a life of seizing the shoreline of people far away and telling them it's for their own good. Luckily, with AGW both the damages and the offsets are fungible.
