Coal pollution mitigation to encourage the introduction of coal pollution mitigation and other technologies to reduce environmental impact. Combustion of coal--which is mostly carbon--produces carbon dioxide as a product of combustion. According to the United Nations Intergovernmental Panel on Climate Change, the burning of coal, a fossil fuel, is a significant contributor to global warming. (See the UN IPCC Fourth Assessment Report). For 1 ton of coal burned, 2.86 tons of carbon dioxide is created. Carbon sequestration technology has yet to be tested on a large scale and may not be safe or successful. Sequestered CO may eventually leak up through the ground,
Natural gas it produces. Anaerobic lagoons produce biogas from manure, while biogas reactors can be used for manure or plant parts. Like landfill gas, biogas is mostly methane and carbon dioxide, with small amounts of nitrogen, oxygen and hydrogen. However, with the exception of pesticides, there are usually lower levels of contaminants. Landfill gas cannot be distributed through utility natural gas pipelines unless it is cleaned up to less than 3% , and a few parts per million , because and corrode the pipelines. The presence of will lower the energy level of the gas below requirements for the pipeline. Siloxanes in
