I work for agriculture companies, and a lot of animal feed comes from by-products of other agricultural products. For example, beet pulp pellets, raffinate, betaine, molasses are all by products of sugar production and are used for animal feed extensively. They are cheap and very shelf stable.

If you include the emissions from manure management you end with 45% of all emissions emanating from livestock production.
Also, that manure management is part of fertilization of plants if I am not mistaken.
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...
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.
If the U.S. were to tax agriculture production of beef, I'm assuming that would be for U.S. farmers so the relevant statistic is emissions in the U.S.
Are you only talking about directly? Because there is a huge amount of indirect costs, such as feed, transport, manufacturing.
In addition, for feeding often this comes from by-products of plant production (sugar by-products, etc...). The only reason corn is so popular imo is because it is so heavily subsidized by our government making it dirt cheap. But grass fed beef is a thing and it's on par or even quite a bit cheaper price wise than fake meat.
Do you mind sharing the name of the company you're referring to? I'm always looking to try new options and support companies in the space.
