As long as we're using fossil fuels, reducing CO2 emission will always bring more bangs for the same buck. It's simply much more effective to not generate CO2

As long as we're using fossil fuels, reducing CO2 emission will always bring more bangs for the same buck. It's simply much more effective to not generate CO2 than try to suck it up from the air (which is only 0.04% CO2!). Get the mankind carbon neutral, and then we can talk about sequestration. (Of course it would be wise to research the technology now, so that we can use it later, but industrial deployment is another story.)
