Carbon offsets are often touted as a solution to humanity’s bad habit of emitting an awful lot of CO2. But how many of us actually know what things like carbon offsets and carbon dioxide removal are all about? This week on Sea Change Radio, we revisit our 2023 discussion with David Ho, a professor in the oceanography department at the University of Hawaii and a co-founder of the nonprofit, [C]Worthy. We discuss his piece in the science journal Nature explaining the shortcomings of carbon offsets, learn more about the mission of [C]Worthy, and take a look at how some corporations greenwash the admirable goal of producing net zero goods. Then, we hear an excerpt of a conversation we had earlier this year with Andrew Kaminsky, a journalist for Triple Pundit as we look at the environmental impacts of extracting various minerals and discuss how mining companies are changing the way they operate.
