The livestock industry says the standard method of calculating the global warming contribution of methane significantly overstates the impact of cattle and is calling for policy changes that could slash the emissions counted against the industry.
Tony Hegarty from the Cattle Council said GWP Star could provide a "more accurate approximation of the actual warming" caused by methane over its lifetime. But significantly, a decrease below the 1997 baseline is counted as emission reduction. In this way, when industry emissions fall below the baseline set 23 years ago, it can claim not to be contributing to additional global warming.
However, other scientists say the rate of breakdown doesn't change the impact of a gas on warming if it's continually topped up by grazing cows, even while emissions break down.
Yes maybe soBUT you can’t escape the fact that each and every one of our four legged friends is a methane gas production facility on legs
