Reversing Climate Change’s Post

Should coproduction impact additionality claims for carbon removals? Coproduction is when a supplier of carbon removal credits produces additional revenue from another source. For example, a direct air capture facility that also produces hydrogen; or, as is the topic of today’s Reversing Climate Change episode, enhanced rock weathering that produces nickel. Most people agree that coproduction is good. However, it conflicts with financial additionality, which states that the carbon removal action would not take place were it not for the carbon credit. In this episode, Nori Cofounder Ross Kenyon interviews Eric Matzner, an alumnus of Carbon Removal Newsroom and Cofounder of Project Vesta who has a new venture called Metalplant. (This is Metalplant's podcast debut!) Their innovative project combines hyperaccumulator plants and enhanced rock weathering to extract nickel from soil and crushed rock while removing carbon from the air. Much of the conversation focuses on a possibly looming intellectual crisis in carbon removal: what does the industry do when it realizes that many of its methodologies are co-producing value besides carbon? Will it try to find a way to square that with conventional applications of financial additionality, or will they abandon or amend additionality to make sure co-producers aren't held down while the world desperately needs them to scale their operations? So much to talk about, and there will almost certainly be more on this topic in the future! Listen here: https://lnkd.in/gYmKuZyG
