One barrel of oil produces approximately 0.43 tonnes of CO2. Cost estimates for carbon capture and storage vary insanely (https://www.statista.com/statistics/1304575/global-carbon-capture-cost-by-technology/), but let's say $100/tonne (direct air capture is likely rather more costly). That means your barrel of oil costs us $43 to cope with the CO2 emitted.

Carbon Capture & Storage makes sense only if that cost is paid at the wellhead.

I think we need to get used to seeing the name Илоном Маском.
