If this is indeed a cost effective way to convert CO2 to more useful chemicals, then it will encourage more CO2 emission into the atmosphere, not less. Industries that are currently CO2 polluting will be encouraged to produce more CO2 so that it can be converted into CO. Some of that additional CO2 will inevitably escape into the atmosphere. As long as the concentration of CO2 in the atmosphere is below the concentration of CO2 in the ground then we'll need a carbon tax to discourage its release in the atmosphere.
