British physicist behind GWP* addresses Australian cattle sector

Beef Central, 29/07/2023

Cattle Australia CEO and Oxford University professor Myles Allen in Canberra on Friday.

OXFORD University Physicist Myles Allen, the independent scientist behind GWP * (Global Warming Potential star) method of accounting for methane emissions, has addressed a group of Australian cattle industry, Government and media representatives in Canberra, at an event organised by Cattle Australia.

Professor Allen was the architect of the GWP* metric that was specifically designed to accurately account for the warming impact of short-lived gasses.

Cattle Australia CEO Luke Bowen thanked Professor Allen for accepting the peak industry council’s invitation to meet with  cattle producers, journalists and policymakers at Hotel Kurrajong in Canberra.

“Professor Allen has clearly demonstrated why we need to look at methane emissions more closely,” Mr Bowen said.

“Beef emissions are dynamic and shouldn’t be measured the same way as CO2.

“Several significant factors are ignored when our emissions are measured this way.

“Short-lived gasses, such as methane, do not have a warming legacy, whereas CO2 lasts thousands of years.

“When the short lifespan of livestock methane is taken into account, you find an industry’s gases stop contributing to warming after 12 years if your herd size is constant.

“What’s more important, is when we cut methane emissions, we reverse our warming impact, something that does not apply to CO2.

“Being part of a natural cycle means the carbon in our emissions goes back into growing the grass and vegetation which sustains our cattle, the natural environment.

“Professor Allen has undertaken a significant analysis of these dynamics to develop a metric that fairly represents the impact methane has on warming.

Professor Myles Allen with Alan Lauder, Carbon Grazing Trust and Cattle Australia director Adam Coffey.

“It’s important to note Professor Allen is an advocate for good science and not an advocate for livestock industries.

“At the same time, our policy settings must be based on the best available science, so our efforts have the most impact.

“It’s time Australia recognised the true warming impact of the grassfed beef industry, which will be neutral by 2026 – and well before net zero.

“Taking the time to understand the climate contribution of the beef industry will put us in a position to take meaningful climate action.”

    Yes Sadly, It Looks Like Australia has to Look Overseas for a Scientist Who Will Design a Dairy Cow Replacement Machine.

    As to Beef, Pork, Mutton ?.
    Science and Enginuity are going to Compete with these as Well.
