Carbon Emissions: Cattle

Volume 463: debated on Tuesday 17 July 2007

To ask the Secretary of State for Environment, Food and Rural Affairs what research he has commissioned into reducing methane emissions from cows. (149644)

For information relating to research into reducing methane emissions from livestock, I refer my hon. Friend to the answer given on 10 July 2007, Official Report, column 1380W.

In addition to our work on reducing emissions from livestock through nutrition, husbandry, genetics, and nutrient management, we are also exploring the potential for the use of anaerobic digestion to reduce methane emissions. Anaerobic digestion can reduce greenhouse gas emissions by capturing methane from the decomposition of organic materials, such as livestock manures and slurries, sewage sludge and food wastes, to produce a biogas. The biogas can be used as a renewable energy source, both for heat and power, and as a transport fuel.
