- Capturing CO2 at scale won’t magically solve emissions because most industrial uses of captured CO2 release it back to the atmosphere, and the market for permanently storing or using that CO2 is tiny compared to global emissions.
- Doing this properly would need massive, expensive infrastructure—millions of miles of pipelines, huge geological storage, and rebuilt steam networks—which is likely economically and logistically unrealistic at the scale needed.
- Even if the technology works, investors and policymakers can create a lot of costly, symbolic projects (virtue theater) that don’t deliver permanent climate benefits and may just enrich startups or rely on short-term subsidies.
