Bodie Cabiyo, PhD

Senior Science Analyst

Environmental Science & Policy + Forest Management

Dr. Bodie Cabiyo works with clients on strategy and procurement to find and vet high-quality carbon offsets projects.

He also leads multiple internal efforts focused on principles and guidance to push the market towards high-quality carbon projects.

Background & Bio

Dr. Cabiyo uses interdisciplinary approaches to investigate nature-based solutions to climate change. He has recently completed his PhD in the Energy and Resources Group at UC Berkeley, where he studied how policy and innovative technology can enable carbon-beneficial forest management. This work bridges industrial ecology, forest economics, and forest ecology.

Dr. Cabiyo's modeling work has focused on the role of innovative wood use in reducing carbon emissions, both in California and East Africa. His applied policy work focuses on improving forest carbon offset protocols. The intent of this work is to promote the more credible translation of carbon dioxide removals to a market context.
