RESEARCH SHEDS NEW LIGHT ON METHANE EMISSIONS FROM THE NORTHERN BEEF HERD

摘要

Beef cattle emit around 200 grams of methane a day, or about 1.5 tonnes of CO_2 equivalents a year, as a by-product of digesting plant material. (CSIRO) New CSIRO research indicates that the amount of methane emitted from cattle fed on tropical grasses in northern Australia is up to 30% less than figures currently used to calculate the northern cattle industry's contribution to Australia's greenhouse gas accounts. Speaking at the Lansdown Field Day near Townsville, Queensland, CSIRO research leader Dr Ed Charmley said the findings would help to refine the nation's greenhouse gas accounting.
