The U.S. Organic Waste Composting (OWC) Protocol provides a standardized approach for quantifying and monitoring the GHG reductions from projects that avoid methane emissions to the atmosphere through the diversion and composting of municipal food waste and food soiled paper waste that would otherwise have been sent to a landfill. This protocol builds largely on the Reserve’s protocol for organic waste digestion projects.

Protocol Revision
The U.S. Organic Waste Composting Protocol is currently undergoing a program revision update. Program revisions are editorial and/or technical in nature and do not require a public comment period, nor do they require adoption by the Reserve’s Board. These revisions do not significantly change the policies or eligibility in the protocol but can change or revise quantification methodologies or monitoring requirements.
Stakeholders may submit revision suggestions to [email protected].
