Suzhou Methane-to-energy Project Phase I and II have a combined annual electricity generation capacity of 27,000,000 kWh. It collects methane produced from waste landfill sites for electricity generation. The project also utilises the high temperatures and residual heat from the gas. It is the first Verified Emission Reduction (VER) project in China that has registered with the Switzerland-based Gold Standard Foundation.
