Livestock emission figures 'grossly exaggerated'

06 Nov, 2009 10:32 AM
THE NSW Farmers’ Association says new research shows the contribution of livestock to greenhouse gas emissions has been grossly exaggerated.

President Charles Armstrong says the association welcomes the peer reviewed study by scientists at the University of California as it clears up a lot of issues.

“The study concluded that direct livestock emissions only account for 3pc of global emissions, showing claims currently being made about livestock are farfetched,” Mr Armstrong said.

“This report identifies numerous errors in the previous analyses of livestock emissions, including the use of elevated Global Warming Potential conversion factors for methane, and including livestock CO2 respiration in the account but not including CO2 fixation by pastures.

“The report also makes the important point that the major emissions associated with livestock are from land clearing for farming land in developing nations and not from the cattle themselves.

“It would be perverse if Australian climate change policy and the Carbon Pollution Reduction Scheme drives meat production to nations with lower environmental standards.

“One commentator recently claimed that the methane from (Australia’s) livestock creates more warming than all our coal fired power stations.

"The hide of this type of exaggeration is amazing."

Readily available official Australian Government data shows that coal emissions are three times greater than emissions from livestock.

Further, under the Kyoto Protocol accounting rules used by the Government, emissions that are sequestered as part of the annual production cycle by plants and in the soil are ignored.

“Global demand for meat is set to double by 2050 in line with increasing population and changing food preferences in Asia," Mr Armstrong said.

"To meet this demand, we need policy that supports sustainable meat production in countries such as Australia."

The lunacy of this (the current estimates) is based on the assumption that all livestock are grain fed or fed in a feedlot situation which is rubbish. The model used by Greenhouse Australia is based on the Blaxter and Clapperton experiments done in England in the mid 1960s.

The main error in the methodology is that the model does not include the greenhouse gasses sequestered from the air to produce the grass that caused the gas in the first place. It is such an obvious error.

It's like saying that if a person eats 1kg per day they will weigh 365 kgs more at the end of the year because we didn't include going to the toilet in the calculations!

The other thing which should be self evident is that if a grassfed population of stock remains constant that the methane bubble doesn't get any bigger or smaller.

Any methane produced in a pasture situation oxidises to form 1 part carbon dioxide, 2 part water in very smart order which goes straight into producing grass for the next generation of animals.

Unfortunately, succesive governments have wound back spending on agricultural research in this country, so we have very few research facilities left to validate this!!!

Something that anyone with even the slightest knowlage of livestock production knew any way!!!

If climate-change billionaire Gore and his fellow-travellers are to be believed, then those giant herbivorous dinosaurs belched and farted themselves into extinction.

It is good to make the press release on this research but it will come to nothing unless Wong is forced to make a public retraction of past gonzo methodology. They simply won't learn a thing unless you rub their noses in it, repeatedly, and with vigour. There was never any excuse for combining land clearing in the total for livestock emissions because they are already recognised as different classes in the IPCC accounting conventions. Australia's cattle herd has only expanded at the same equivalent rate as the sheep herd has contracted. So we can be absolutely certain that Australian livestock methane emissions have remained essentially the same for the past century.

If you read the paper, you'll find that is does *not* say that only 3% of global emissions come from livestock. That estimate relates to US emissions only. The point the authors are trying to make is that most developed countries are actively clearing land for livestock production, whereas the US is not. Australia is. I'm afraid that NSW Farmers have misread the report's conclusions.

This sounds like hot air to me!

Congrats NSWFA. It is about time someone led us to dispute these very debatable scientific assumptions that could destroy agriculture. Most farmers are making changes and working to protecting our environment. We cannot survive fraudulant taxes based on erroneous science.

The debate is full of imposters - most of the passionate proponents of man-made climate change lack relevant science qualifications. I note Mr Gore is not a scientist. ABARE is funded by the government which will collect the tax - they (ABARE) are grappling with how to not tell the truth so they can keep their funding. PS: The intergovernmental panel on climate change (IPCC) needs an extra "C" in it. Its name should be Intergovernmental Panel for Capitalising on Climate Change (IPCCC).

You mean that these lying cheating global warming boof heads are "Exaggerating " ----- Get out !!!!

Michael must have had his head in a paper bag when broadscale clearing was banned in NSW & Qld. The only clearing that still takes place in Australia is clearing of young regrowth. And the carbon released from this activity is the same carbon that was absorbed by the regrowth just a few years earlier. But of course, the climate trolls refuse to give any credit for the carbon that has been captured, choosing instead to demonise farmers for the gross emissions. It is another sordid example of climatista misrepresentation by omission. As if anyone not born yesterday needed another example.
