Today I’m joined by Susan Cook-Patton, Lead Reforestation Scientist at The Nature Conservancy, to get into the weeds on applying science to forest carbon investment decision making. In this conversation, Susan breaks down what “durability” really means in practice—how risks vary by location, project type, and species, and why investors should be assessing likelihood, severity, and the probability of regrowth. She shares how her team is developing tools and maps to help investors quickly identify higher- and lower-risk landscapes, bringing greater certainty to carbon outcomes under future climate conditions. We talk project design choices that can reduce wildfire impacts, the role (and limitations) of buffer pools, and emerging alternatives like permanence trust funds and storage years. Susan also shares where remote sensing is improving fast—and why data sharing may be the biggest unlock for better, cheaper carbon accounting.

“It’s not about eliminating all risks. It’s about understanding them so you can plan appropriately and put compensation mechanisms in place if disturbances do occur.”
