I'm not Patrick Collison, but if I were then I might say that there are already a bunch of impressively plausible-looking carbon capture and sequestration technologies, they look like our best bet on the margin, and what they mostly need is a large enough early customer base to let them scale up and reduce cost. As it happens, there's a program called Stripe Climate which aims to do exactly this! Money comes from Stripe and from businesses that would like to be able to truthfully say that they donate a percentage of purchases to fight climate change. It looks well thought-out and credible, at least to my eye. They elaborate more on the rationale here: https://stripe.com/climate https://stripe.com/climate
