Methane (Ch4) is a greenhouse gas that only lasts an average of 12 years in the atmosphere; it is an extremely powerful warmer during that period. One molecule of methane warms about 25 times more than CO2 over 100 years (and 72 times as much over 20 years). Reduction methods are recovery and use from coal mines and oil production; reduced leaks from natural gas production and pipelines, improved management of municipal waste and wastewater, including recycling, composting, and gas capture and use, anaerobic digestion of livestock manure, improved rice irrigation etc. (1),

Bio-methane from biomass offers an increasing substitution for fossil natural gas. The larger part of bio-methane is still produced from waste and wastewater at present and provides significant CO2 savings. Methane gas vehicles can play an important role in urban and medium distance transport. (2)
