How much carbon dioxide is produced by livestock?
Farmed animals – referred to as livestock – generate over 14 percent of all anthropogenic emissions, with estimated totals hovering around seven gigatonnes of carbon dioxide emitted every year. The bulk of these emissions are due to raising cattle for meat and dairy, contributing 60 percent of total livestock emissions. These emissions are thanks to the vast amounts of resources cows consume, the land they require for pasture (in the case of beef cattle), and other manure they produce. Cow manure contains nitrous oxide and methane, the latter being one of the most potent greenhouse gasses due to its outsized ability to absorb heat.

Cement (3%): carbon dioxide is produced as a byproduct of a chemical conversion process used in the production of clinker, a component of cement. In this reaction, limestone (CaCO 3) is converted to lime (CaO), and produces CO 2 as a byproduct. Cement production also produces emissions from energy inputs – these related emissions are included in ‘Energy Use in Industry’.
What is the percentage of organic matter in wastewater?
Wastewater (1.3%): organic matter and residues from animals, plants, humans and their waste products can collect in wastewater systems. When this organic matter decomposes it produces methane and nitrous oxide.
What are fugitive emissions?
Fugitive emissions from oil and gas (3.9%): fugitive emissions are the often-accidental leakage of methane to the atmosphere during oil and gas extraction and transportation, from damaged or poorly maintained pipes. This also includes flaring – the intentional burning of gas at oil facilities. Oil wells can release gases, including methane, during extraction – producers often don’t have an existing network of pipelines to transport it, or it wouldn’t make economic sense to provide the infrastructure needed to effectively capture and transport it. But under environmental regulations they need to deal with it somehow: intentionally burning it is often a cheap way to do so.

The average daily CO2 emission for dairy cows producing 63 pounds of milk per day was 6,137 liters. The range was 5,042 to 7,427 liters per day over a six-month monitoring period. A recent paper reported the CO2 emissions using data summarized from the USDA Energy Metabolism Unit. This is a large dataset obtained from animals using the indirect respiration chambers.
What percentage of methane is produced by cows?
A second approach is to express methane production as a percent of the gross energy intake. A 2008 study indicated that 6 to 10 percent of the total energy intake was emitted as methane. The average methane production for lactating dairy cows was 5.49 percent of gross energy (GE) intake using the USDA Energy Metabolism Unit database. The range was 2.53 to 7.82 percent of GE. These same workers reported an average methane production of 7.89 percent of GE for dry cows, with a range of 3.47 to 10 percent. It is not clear how low this value could be and still maintain rumen function and milk production.
What are the main sources of methane emissions from dairy farms?
The main sources of methane emissions on dairy farms are enteric emissions and manure. Enteric methane accounts for about 75 percent of the total on-farm methane emissions. Mean daily methane production was reported as 587 liters per day for cows averaging 63 pounds per day.
How much ammonia is in dairy cows?
A number of papers have reported estimated annual ammonia emissions for dairy cattle. A yearly emission factor of 84 pounds of NH3 per dairy cow per year was reported by EPA (2004). An annual emission of 88 pounds NH3 per dairy cow per year was reported from on-farm research on a 185-cow dairy in Washington. Three dairy herds in Wisconsin were monitored and annual NH3 emissions of 41.8 to 44 pounds per cow were determined.
What is the major nutritional variable that influences N use efficiency and potential ammonia emissions?
A major nutritional variable that influences N use efficiency and potential ammonia emissions is the rumen balance of RDP relative to requirements. One paper examined this question using diets with 12.9, 13.4 and 15.4 percent CP for dairy cows producing about 66 pounds of milk per day. Urinary N excretion and cumulative manure NH3 emissions were reduced on the lower CP diets.
How much N2O is in cows?
A paper from California reported a N2O emission rate of about 0.02 grams per cow per hour for cows housed in environmental chambers. A simulation model approach has also been used to examine total N2O emissions from a dairy farm. This model used a 100-cow dairy herd housed in a freestall barn with milk production of 19,800 pounds per cow per year. Manure was stored as slurry and spread on the cropland twice per year.
What percentage of the total N excreted by dairy cattle is in the urine?
The following points summarize this process: • 30 to 70 percent of the total manure N excreted by dairy cattle is in the urine. • 50 to 90 percent of the total N in the urine is present as urea.
