Claim: Burning fuel to produce fertiliser to grow feed, to  produce meat and to transport it - and clearing vegetation for grazing -  produces 9 per cent of all emissions of carbon dioxide, the most common  greenhouse gas.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Animal husbandry is also responsible for greenhouse gas production of CO 2 and a percentage of the world's methane, and future land infertility, and the displacement of wildlife.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Other anthropogenic GHG emissions associated with livestock production include carbon dioxide from fossil fuel consumption (mostly for production, harvesting and transport of feed), and nitrous oxide emissions associated with use of nitrogenous fertilizers, growing of nitrogen-fixing legume vegetation and manure management.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The IPCC (Intergovernmental Panel on Climate Change) has estimated that agriculture (including not only livestock, but also food crop, biofuel and other production) accounted for about 10 to 12 percent of global anthropogenic greenhouse gas emissions (expressed as 100-year carbon dioxide equivalents) in 2005 and in 2010.Cows produce some 570 million cubic metres of methane per day, that accounts for from 35 to 40% of the overall methane emissions of the planet.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The vast majority of anthropogenic carbon dioxide emissions come from combustion of fossil fuels, principally coal, oil, and natural gas, with additional contributions coming from deforestation, changes in land use, soil erosion and agriculture (including livestock).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Greenhouse gases (GHGs) can be emitted through land clearance and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, transportation and other services.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes, transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and nitrous oxide from fertilizer use).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In the UK, for example, agricultural-related emissions may account for approximately 40% of the overall food chain (including retail, packaging, fertilizer manufacture, and other factors), whereas greenhouse gases emitted in transport account for around 12% of overall food-chain emissions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The greenhouse gases carbon dioxide, methane and nitrous oxide are produced during the manufacture of nitrogen fertilizer.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Coal production is a major contributor to global warming: burning coal generates large quantities of carbon dioxide and mining operations can release methane, a known greenhouse gas, into the atmosphere.
