We performed a comprehensive, quantitative study of the five most-used cookstoves offset methodologies, examining how the methods used to estimate their emissions reductions compare with best methods from the academic literature.
Reducing Emissions from Deforestation and Forest Degradation (REDD+)
REDD+ is the project type with the most credits on the voluntary carbon market — about a quarter of all credits to date. We brought together an interdisciplinary team of researchers to perform a quality assessment of the four most-used REDD+ methodologies.

Offset Program Development for the University of California
We led the development of the University of California's strategy for procuring offsets. The broader goal was to explore, model, and develop methods, resources, and guidelines for how major offset buyers can procure high-quality offsets aligned with the institution's mission. In the end, the University system replaced its offset program with accellerated direct decarbonization goals, a fee per tonne to be reinvested in direct decarbonization, and a carbon shadow price equal to the equity-weighted social cost of carbon.

Voluntary Registry Offsets Database (VROD)
The Voluntary Registry Offsets Database contains all carbon offset projects, credit issuances, and credit retirements listed globally by five major voluntary offset project registries.

Repository of Articles on Offset Quality
We maintain a repository of peer-reviewed articles and independent research institute reports that assess the outcomes and credit quality of carbon market projects and protocols.
