In principle, removing a ton of CO2 needs to be cheaper than the cost of adding a ton of CO2. And it will be, at some point in the future; it’s not intended to compete with preventing CO2 emissions today. We need to start work on the technology now though, even if it’s not immediately scaleable. The technology to remove excess CO2 from the atmosphere at scale will be required over the 21st Century to return the CO2 levels to pre-industrial levels, which our forecasts have priced in.
