The methodology is applicable to activities that involve installation of equipment for reducing methane slip, i.e. methane that escapes unburnt from marine and land-based (stationary) internal combustion engines using natural gas or other methane-rich fuel, including fuels derived from renewable sources. The equipment that reduces methane slip is installed in the exhaust gas stream and includes instruments for measuring the concentration and flow rate of methane and other gases before and after the component that reduces methane emissions, permitting an accurate quantification of methane emissions reduction.
This methodology aims presents a standardised approach to measure, certify and verify greenhouse gas (GHG) emissions reductions for activities involves use of biofuels blending with fossil bunkers in sea vessels (as bunker fuels). The counterfactual scenario looks at GHG emissions from conventional fossil fuel traditionally used to power sea vessels. The typical project activity for this methodology – biofuel bunkering in sea vessels - includes all supply chain processes (from waste oil collection to loading the blended biofuel onto a vessel), measuring emissions from the entire supply chain of the biofuel and comparing that against the GHG emissions from the fossil fuel options for shipping transport.

The methodology presents requirements to quantify changes in greenhouse gas (GHG) emissions and soil organic carbon (SOC) stocks through the adoption of improved agricultural practices. Activities can achieve avoidance of emissions as well as sequestration of carbon in the soil, both which result in increased SOC content.
