What is "mootral"

Mootral is the name given to a programme to reduce methane emissions from ruminant animals, chiefly cows and sheep, but also goats. Methane is a major target greenhouse gas and in the 4th protocol report of the Intergovernmental Panel on Climate Change (IPCC) is recommended to increase from a x23 to x72 multiplier because of the magnitude of its effect relative to carbon dioxide and short longevity in Earth's atmosphere.
