This new 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. Accurate measurement of the methane emission reduction is made possible by installing a piece of equipment in the exhaust gas stream – which includes instruments for measuring the concentration and flow rate of methane and other gases before and after its application.
