One of President Biden’s signature achievements to combat climate change has been the approval of billions of dollars in federal subsidies to encourage carbon capture and storage. It sounds good: capturing carbon dioxide from industry, then piping it underground so it can’t heat the planet. But most of these projects don’t really help the climate. They provide taxpayer money to oil and gas companies, who use captured carbon to force more oil and gas out of the ground. We interview an expert on carbon capture, MIT Professor Charles Harvey, who was the scientific advisor to a pioneering carbon capture company who discovered, firsthand, that the technology was not economically viable. We ask Professor Harvey: What would happen if the incoming president, Donald Trump, a climate change denier, followed the advice of his allies at Project 2025 and killed all federal funding for carbon capture?
