    Carbon needs to be captured were there is a lot of carbon in the air. So especially around cities with lots of car traffic, or around fossil fuel power plants…

    So… It would be better to stop car traffic and fossil fuel power plants first, before doing carbon capture…

      CO2 doesn’t vary much in concentration by how close you are to an emission source unless you are literally sucking air out of a tailpipe. You might get a 10-20% increase in the centre of a city instead of the countryside, hardly enough to make up for being somewhere with so much energy coming in that they frequently have to curtail it (which could then be used for this instead).

      This isnt CCS which cheaply turns CO2 into an inert form of carbon, its an expensive process for turning CO2 into a very useful form.

      They could route emissions through a system like this directly from smoke stacks, capturing the carbon before it even reaches the atmosphere
