I think that the point is that if, today, you could spend $100 on pulling 1 ton of CO2 from the air, or spend $100 on green energy which prevents 2 tons of CO2 going into the air, the second is more important, even if we need to be extracting CO2 from the air. There's no point in extracting 1 ton of CO2 and putting 2 tons of CO2 back up there.
