A dairy cow can produce up to 400 litres of methane per day! When burned, this is enough energy to power a small fridge for a day. Some scientists have harnessed methane emitted from cows in backpacks (see photo and video below) however scaling this up to all 10 million cows (this includes all calves, young bulls etc in the UK alone) could be problematic!

Swine accounted for 42 percent (25 MMTCO 2 e), and dairy cattle accounted for 49 percent (28 MMTCO 2 e), of total methane emissions from livestock manure in 2009. Enteric fermentation (food digestion) in ruminant animals also produces methane emissions, and digestion by cattle accounts for 96 percent of U.S. methane emissions from this source.

CO 2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions. All figures here are expressed in CO2-equivalents.

Image: FAO. So attention has turned to putting a cork in the volume of methane cows produce, by targeting their gut microbes. Researchers looked at more than 1,000 cows on farms throughout Europe, and found they had a large proportion of their gut bacteria in common.

Methane Production and the Dairy Cow Agriculture contributes approximately 6 to 7% of the total U.S. greenhouse gas emissions. Methane from enteric (microbial) fermentation represents 20% and manure management 7% of the total CH 4 emitted. Ruminants (beef, dairy, goats, and sheep) are the main contributors to CH 4 production.

Methane (CH 4) accounts for about 50 percent of the total. Nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) represent almost equal shares with 24 and 26 percent, respectively. Top ↑

Each year, a single cow will belch about 220 pounds of methane. Methane from cattle is shorter lived than carbon dioxide but 28 times more potent in warming the atmosphere, said Mitloehner, a professor and air quality specialist in the Department of Animal Science .

[xi] A single cow can produce between 66-132 gallons of methane a day. The average US vehicle gas tank can hold about 16 gallons of gas. [xii] “The US meat industry produced some 1.4 billion tons of waste in 1997— five tons of animal waste for every US citizen.

Fifty-six percent of the greenhouse gas emissions associated with U.S. beef cattle production is the methane cattle naturally belch. Since it’s unlikely these emissions are driving warming, clearly communicating that a carbon footprint doesn’t always translate into climate change is a focus of the Beef Checkoff Program.

Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
Methane is a far more potent greenhouse gas than CO2, even though it only lasts about a decade in the atmosphere, whereas CO2 persists for a couple of centuries. A continued rise in the amount of methane in the air could easily cancel out any near-term progress we make in reducing CO2 emissions.

Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms.It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite.
Methane (US: / ˈ m ɛ θ eɪ n /, UK: / ˈ m iː θ eɪ n /) is a chemical compound with the chemical formula CH 4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane and is the main constituent of natural gas.
  • Methane is nontoxic on its own but can become lethal when it combines with another gas. Methane causes asphyxiation by displacing oxygen. It may produce symptoms of dizziness and headache, but these often go unnoticed until the brain signals the body to gasp for air.
