MoFuSS: Managing uncertainty in Cookstoves projects

BeZero has been utilising the Modeling Fuelwood Savings Scenario (MoFuSS) as a tool in ratings since May 2024, although as of May 2025, we have rated no post-issuance projects that have used MoFuSS in their own calculations.

Earlier this year, we hosted a workshop with the creators of MoFuSS to delve into the intricacies of the model and discuss how it can help to improve the integrity of cookstove projects.

  • The fraction of non-renewable biomass (fNRB) is site-specific: Estimates depend on local supply-demand dynamics. MoFuSS accounts for woodfuel transport from supply zones to demand centres, offering spatially explicit results grounded in observed biomass trends. 

  • Improved accuracy and integrity: Compared to older methods that often overestimate deforestation from woodfuel use, MoFuSS minimises overcrediting, while enabling developers to model project-specific boundaries and improve granularity.

  • Estimations of fNRB will always have uncertainties: MoFuSS is built to address uncertainties and can provide robust, representative values for project developers.
