How does biogas help reduce effects of climate change?

Biogas is made up of methane and carbon dioxide, which are powerful greenhouse gases. Anaerobic digesters are designed to capture these gases so they do not escape to the atmosphere. In most cases, the feedstocks used in digesters would have released methane directly as they decomposed in lagoons or landfills. In addition, using biogas for heat or electricity means that less energy needs to be produced by power plants. This reduces the amount of carbon dioxide emitted to the atmosphere by burning fossil fuels.
