The 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. This protocol was first adopted by the Reserve Board in June 2010.
