The world's CDR policies are organized around the premise that working together, solutions like direct air capture, biochar and enchanced rock weathering can reach 10 gigatons per year of CO2 removal by mid-century. Can they though? And what if we need more than 10?

What do we mean when we say governments should become more involved in CDR? The history of oil and waste management offer two compelling examples.

UNEP's latest report concedes the battle against 1.5. But it doubles down on our emissions reductions strategy, and pushes CDR to a remote influence at best.

Conventional wisdom holds that our CDR goals should be set to around 10 gigatons per year. But where did this number come from? And what assumptions are baked into it? Based on our current CO2 emissions reality, that number may actually be closer to 100 gigatons.

What if cities managed carbon dioxide the same way they already manage their trash, recycling, and compost operations? By deploying thousands of small collection units, cities working together could make a gigaton-scale impact.
