Balloon materials vary in lifespan, or durability, though – let’s say there are two types: one holds the CO₂ for exactly 20 years before popping, another for thousands of years with an innovative new material. How do you measure the climate impact of storing captured CO₂ for 20 years vs. thousands of years? And what carbon offset claims would you make for each? Although a little simplistic, this analogy highlights one of the most important complexities in carbon offsetting: durability. The field hasn't yet agreed upon frameworks for comparing the climate benefit of a tonne of CO₂ stored in soil for 20 years with a tonne that is permanently mineralized. On the market today, both are sold as “one tonne of carbon credit” and the buyer has to do the hard work of figuring out how they differ in efficacy. The basic questions are: What is the role of carbon storage that only lasts a decade or two relative to storage that lasts for thousands of years? How can we use short-term storage as part
