Methane
Methane (CH4) is the simplest alkane and the main component of natural gas. It is the second most important manmade greenhouse gas (GHG) after carbon dioxide and it is responsible for more than a third of total anthropogenic climate forcing. The World Bank estimates that actions to reduce methane emissions represent as much as half of the potential that can be achieved in avoided global warming by 2050.

Methane is the second most abundant GHG accounting for 14 percent of global GHG emissions. Methane is considered a short-term climate forcer, meaning that it has a relatively short lifespan in the atmosphere, approximately 12 years. While methane is in the atmosphere for a shorter period of time and is emitted in smaller quantities than CO2, its ability to trap heat in the atmosphere, which is called its global warming potential, is 25 times greater than that of CO2.

Methane emitted from manure and agro-industrial waste management systems can be captured using anaerobic digestion (AD) technology. A variety of AD technologies are available, including small-scale digesters, covered anaerobic lagoons, plug flow digesters, complete mix digesters, and advanced digesters.

AD projects developed at an agricultural site not only reduce GHG emissions and produce clean energy but also act to improve air and water quality, reduce odours, improve nutrient management, increase sanitation, stimulate rural economic development, and promote sustainable environmental development.

Capturing and harnessing methane for energy production has by far the largest positive social and environmental impact per invested capital within renewable energy sector. This is clearly demonstrated in the table below:
