To have any chance of limiting global warming to 1.5 degrees Celsius–the threshold if the world wants to avoid the worst impacts of climate change–a recent report says that we’re going to need not just to cut emissions, but capture CO2 that’s already in the atmosphere. Some of that technology already exists, like machines that suck carbon dioxide directly out of the air.
But a new request for startups from Y Combinator, the Silicon Valley startup accelerator, calls for businesses to take much wilder approaches to capturing carbon. As the accelerator puts it:
The frontier technology ideas presented in this RFS straddle the border between very difficult to science fiction. While these approaches are not our Plan A, we think it’s time to get Plan B ready. They may seem like moonshots now but our goal is to try to come up with technically feasible solutions at realistic costs. If we can do that, we then need to have a global conversation about the tradeoffs.
