Livestock and Climate Change: Facts and Fiction

http://blogs.ucdavis.edu/egghead/2016/04/27/livestock-and-climate-change-facts-and-fiction/

"...

One argument often made is that U.S. livestock GHG emissions from cows, pigs, sheep and chickens are comparable to all transportation sectors from sources such as cars, trucks, planes, trains, etc. The argument suggests the solution of limiting meat consumption, starting with “Meatless Mondays,” to show a significant impact on total emissions.

When divorcing political fiction from scientific facts around the quantification of GHG from all sectors of society, one finds a different picture.

Leading scientists throughout the U.S., as well as the U.S. Environmental Protection Agency have quantified the impacts of livestock production in the U.S., which accounts for 4.2 percent of all GHG emissions, very far from the 18-51 percent range that advocates often cite.

Comparing the 4.2 percent GHG contribution from livestock to the 27 percent from the transportation sector, or 31 percent from the energy sector in the U.S. brings all contributions to GHG into perspective. Rightfully so, the attention at COP21 was focused on the combined sectors consuming fossil fuels, as they contribute more than half of all GHG in the U.S.

2. Still, we should encourage livestock owners...

To capture the methane gas and use it for fuel. That would also reduce the runoff from feed lots into water sources.

Which I'm told is quite a problem.
