Livestock Agriculture is Just a Small Contributor in Greenhouse Gas Emissions

Lying vegan propagandists and militant animal-rights activists are spreading lies about global livestock agriculture being a major cause of global Greenhouse Gases, but they are not able to show any evidence, they just keep repeatedly making empty false claims.

The truth is world's biggest Greenhouse Gas producers are electricity and heat production, manufacturing industry, consumerism and transportation! Greenhouse Gas emissions from fossil fuel combustion and industrial processes contributing about 78% of the total Greenhouse Gas emission increase from 1970 to 2011.

The information below came from US Environmental Protection Agency website:
https://www3.epa.gov/climatechange/ghgemissions/global.html#four

Total GHG (Greenhouse Gas) emissions from the entire crop and livestock agriculture in the world account for only 10% of the total global GHG emissions.

High percentage of the global GHG emissions, about 3/4, are carbon dioxide, not methane. Greenhouse Gas emissions from agriculture consist of non-CO2 gases, specifically methane (CH4), and nitrous oxide (N2O). Crop and livestock agriculture has only a tiny direct carbon dioxide emission ratio, crop and livestock agriculture produces mostly methane in its GHG emissions.

Crop agriculture produces as much GHG and methane as livestock agriculture does. Rice cultivation alone contributes 10%, synthetic fertilizers contribute 13%, burning savana contributes 5%, crop residues contribute 4%, cultivation of organic soil for vegetables contributes 3% of the total global GHG emissions by agriculture sector.

These are four major Greenhouse Gases:

Carbon dioxide (CO2) contributes 76% of the total Greenhouse Gas emission globally. Fossil fuel use is the primary source of CO2. Agriculture doesn't contribute much to global CO2 emission. Both Crop agriculture and livestock agriculture may help remove CO2 from the environment.

Methane (CH4) contributes 16% of the total Greenhouse Gas emission globally. Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4 emissions.

Nitrous oxide (N2O) contributes 6% of the total Greenhouse Gas emission globally. Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Biomass burning also generates N2O.

Fluorinated gases (F-gases) contributes 2% of the total Greenhouse Gas emission globally. Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases.

2010 Global Greenhouse Gas Emissions by Economic Sector

Electricity and Heat Production 25%
The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.

Industry 21%
Greenhouse Gas emissions from industry primarily involve fossil fuels burned on-site at facilities for energy. This sector also includes emissions from chemical, metallurgical, and mineral transformation processes not associated with energy consumption and emissions from waste management activities. (Note: Emissions from industrial electricity use are excluded and are instead covered in the Electricity and Heat Production sector.)

Agriculture, Forestry, and Other Land Use 24%
Only less than half of these Greenhouse Gas emissions come from agriculture (cultivation of crops and livestock). This estimate does not include the CO2 that ecosystems remove from the atmosphere by removing carbon in biomass, dead organic matter and soils, which offset approximately 20% of emissions from this sector.

Transportation 14%
Greenhouse Gas emissions from this sector primarily involve fossil fuels burned for road, rail, air, and marine transportation. Almost all (95%) of the world's transportation energy comes from petroleum-based fuels, largely gasoline and diesel.

Residential & Commercial Buildings 6%
Greenhouse Gas emissions from this sector arise from on-site energy generation and burning fuels for heat in buildings or cooking in homes. (Note: Emissions from electricity use in buildings are excluded and are instead covered in the Electricity and Heat Production sector.)

Other Energy 10%
This source of Greenhouse Gas emissions refers to all emissions from the energy sector which are not directly associated with electricity or heat production, such as fuel extraction, refining, processing, and transportation.


People, beware, don't fall for the lies by those lying vegan trolls/shills, go to the US Environmental Protection Agency website, linked below, and read up on Greenhouse Gas Emissions, you can find the above real information and a lot more there.


The information below came from United Nations Food and Agriculture Organization (UN FAO)

In 2011: 

Enteric fermentation from livestock contributes about 4% of total global Greenhouse Gas emissions, or 40% of total global emissions from agriculture. GHG emissions from enteric fermentation consist of methane (CH4) produced in digestive systems of ruminants and to a lesser extent of non-ruminants. Estimates include emissions by cattle, buffaloes, sheep, goats, camels, llamas, horses, mules, asses and swine. The GHG issue in enteric fermentation can easily be solved, there are natural safe methods to reduce enteric fermentation, more researches are underway.

Livestock manure management contributes about 0.7% of total global Greenhouse Gas emissions, or 7% of total global emissions from agriculture. Greenhouse Gas emissions from agricultural soils consist of methane and nitrous oxide produced in the following sub-sectors: synthetic fertilizers, manure applied to soils, manure  left on pasture, crop residues, cultivation of organic soils and synthetic fertilizers. GHG problem in manure management can easily be solved if serious attention if given on it.

Rice cultivation contributes about 1% of total global Greenhouse gas emissions, or 10% of global agriculture GHG emissions. GHG emissions from rice cultivation consist of methane (CH4) produced from the anaerobic decomposition of organic matter in paddy field. There is not any good solution to water paddy rice cultivation, the only way is GMO rice but who wants to eat Frankenstein rice?

Synthetic fertilizers contributes about 1.4% of total global GHG emissions, or 14% of total emissions from agriculture. GHG emissions from synthetic fertilizers consist of nitrous oxide from synthetic  nitrogen added to managed soils.

Manure applied to soils as fertilizer contributes about 0.4% of total global GHG emissions, or about 4% of total emissions from agriculture. GHG emissions from manure applied to soils consist of nitrous oxide (N2O) produced from nitrogen additions. Estimates of emissions include manure from cattle, buffaloes, sheep, goats, camels, llamas, horses, mules, asses, ducks, turkeys, chickens and swine.

Manure left on pasture was about 1.5% of total global GHG emissions, or 15% of total GHG emissions from agriculture. GHG emissions from manure left on pasture consist of nitrous oxide (N2O) produced from nitrogen additions to managed soils from grazing livestock. Estimates include emissions  by cattle, buffaloes, sheep, goats, camels, llamas, horses, mules, asses, ducks, turkeys, chickens and swine.

Crop Residue was about 0.4% of total global GHG emissions, or 4% of total GHG emissions from agriculture. GHG emissions from crop residues consist of direct and indirect nitrous oxide (N 2 O) emissions from nitrogen in crop residues and forage/pasture renewal left on agricultural  fields by farmers. Specifically, N 2 O is produced by microbial processes of nitrification and  de-nitrification taking place on the deposition site (direct emissions), and after volatilization/ re-deposition and leaching processes (indirect emissions). Emissions of crop residues were dominated by rice and wheat, both contributing 27%, followed by maize (21%) and soybeans (10%).

Cultivation of organic soils was about 0.3% of total global Greenhouse gas emissions, or 3% of total emissions from agriculture. GHG emissions from cultivation of organic soils are those associated with nitrous oxide (N2O) emissions from the drainage of cropland and grassland histosols (peatlands). Emissions from cultivation of organic soils in agriculture originate for three-fourths in cropland areas.

Burning of savanna was about 0.5% of total global Greenhouse gas emissions, or 5% of total emissions from agriculture. Greenhouse gas emissions from burning of savanna consist of methane (CH 4 ) and nitrous  oxide (N 2 O) produced from the burning of vegetation biomass in the following five land cover  types:  savanna, woody savanna, open shrubland, closed shrubland  and grassland. Emissions from burning of savanna were dominated by savanna (39%) and woody savanna  (35%), followed by open shrubland and grassland (14% and 9%, respectively). Africa was by far the largest emitter (70%), followed by Oceania (19%) and the Americas.

Burning of crop residues was about 0.05% of total global Greenhouse gas emissions, or 0.5% of total emissions from agriculture. Greenhouse gas emissions from burning crop residues consist of methane (CH 4 ) and nitrous oxide (N2O) produced by the combustion of crop residues burnt in agricultural fields. Emissions from burning of crop residues were dominated by maize, contributing 45%, followed by wheat and rice (26% and 25%), respectively.

A must read for anyone really wants to know the truth, a very well written detailed report on agriculture in relation to GHG by United Nations Food and Agriculture Organization (UN FAO): Agriculture, Forestry and Other Land Use Emissions by Sources and Removals by Sinks, 1990-2011 Analysis

This report discusses new knowledge on anthropogenic greenhouse gas (GHG) emissions from agriculture, forestry and other land use (AFOLU) activities.
