According Food and Agricultural Organization (FAO) of the UN 2006 report livestock were responsible for 18% of all human-related greenhouse gas production. 14.5% according to 2013 report.
Of that 43% is Enteric.
There may only be 9% GHG emissions in the US, but beef also comes from other countries where these emissions are very different. See Regional and Production System differences.
From the article -- There was an approximately 4-fold difference in emission intensity between the top 10% of producers and the bottom 10% of producers within a system.
This is a good thing. More vegetarian fast-food options are coming down the pipe.
I've recently seen a few ads from Harvey's, went there and had a burger. It's not the same as beef but it's a burger.
The good part of having a vegetarian burger is that I don't enter into catatonic state for about 1/2 hour after I had fast food. I can eat fast food when meat is replaced with something else.
Hopefully carbon taxes and such would kick in at some point and would include the real environmental cost of beef, so the switching to plant based beef would be even more swift.
I'm using the article 'Beef Cattle and Greenhouse Gas Production' from Ministry of Agriculture, Food and Rural Affairs. http://www.omafra.gov.on.ca/english/livestock/beef/news/info...
