Animal agriculture in the U.S. contributes approximately 3.5% of all man-made greenhouse gases (GHGs). If you look at pork production, it accounts for just 0.34% of all emissions. (Source: U.S. EPA Greenhouse Gas Inventory released April, 2015).
When you total up all the GHG emissions from a particular activity or process, it is called a carbon footprint. The procedure used to decide which GHG emissions are included in this total is a life-cycle assessment (LCA).
What Is a Carbon Footprint and How Is It Used?
A carbon footprint gives you a snapshot in time of the GHGs produced by the activity or process being evaluated. The number generated is especially useful for comparing different processes or different times.
Some reasons a farm, company, or industry would calculate a carbon footprint include:
Identifying “hot spots” in the system to prioritize areas where reductions can be made
Creating a baseline measure for comparing over time
Looking at “what-if” scenarios and comparing different options to see how each affects GHG emissions
What Goes Into a Life Cycle Analysis?
In order to be able to compare carbon footprints of different farms or different industries, the life-cycle analysis (LCA) needs to use the same parameters. To do this, many people rely upon standardized procedures such as those created by the International Organization for Standardization.
For the pork industry, the pork supply chain is broadly divided into eight stages:
feed production;
live animal production;
delivery to processor;
processing;
packaging;
distribution;
retail;
consumption/disposal.
The most important thing to remember is that if you compare two or more carbon footprints to each other, the LCA used needs to be the same. If you try to compare footprints generated using different LCAs, you will not get a true comparison.

A carbon footprint is a total of all the greenhouse gas emissions (GHG) from a process or industry. A life cycle assessment (LCA) is the process used to figure out what GHG emissions will be included in the footprint. More technically, it is systematic way of looking at a product’s complete life cycle and calculating a “footprint”. In addition to carbon footprints, there are efforts to calculate land, water, and other environmental footprints.
Below are highlights from several different reports that looked at the carbon footprint of the pork industry on a national and international scale. A comparison between different ways to raise pigs was also highlighted.
The report concluded that the carbon footprint to prepare and consume a 4 oz serving of pork was ~2.5 lbs of carbon dioxide equivalents. Figure 1 (below) from that report shows the relative breakdown of the industry’s estimated greenhouse gas emissions:
Live animal production made up 62.1% of the emissions. That is further broken down and presented in second column (right).
Processing – 5.6%
Retail – 7.54%
Consumption – 23.5% including refrigeration, cooking, and methane from food waste in landfill
Packaging (1.3%);
Comparison Over 50 Years of Production
Another example of an industry-wide analysis, this one comparing over time, is a “50-year comparison of the carbon footprint of the U.S. swine herd 1959 – 2009” (29 pp; PDF). The pork industry overall emits more total greenhouse gases than 50 years ago, but actually emits much less per pound of pork produced because of improvements in efficiency.
From that publication:
The U.S. swine industry produces pigs far more efficiently today (2009) than in 1959. The number of hogs marketed has increased 29% (87.6 million in 1959 to 112.6 million in 2009 after removing market hogs imported directly to harvest) from a breeding herd that is 39% smaller. The efficiency gain is even more impressive when measured against the total dressed carcass weight harvested. Dressed carcass yield leaving the farm has nearly doubled in 50 years from 12.1 billion pounds to 22.8 billion pounds. This increase in productivity has resulted in an increase of 2,231 pounds (2.5x) of carcass harvested annually per sow – year. Today, it takes only five hogs (breeding and market) to produce the same amount of pork that required eight hogs in 1959.
High-profitability operations have consistently lower impacts compared to low-profitability operations for both commodity and deep-bedded niche piglet production.
Global Assessment from Backyard to Industrial Systems
On an international scale, the report “Greenhouse gas emissions from pig and chicken supply chains” was published in 2013. This study looked at all scales of farms from backyard pigs to industrial production (large confinement operations). Over the entire scale, they estimated that the carbon footprint of pork for every kg (~2.2 lbs) of pig carcass weight has an emissions intensity of 6.1 kg of carbon dioxide equivalent.
This report found that backyard systems, especially in some parts of the world, have low emissions, largely due to by-product or “second-grade” feeds. Industrial pig systems tended to have more emissions intensity than backyard systems, with the emissions from liquid/slurry manure management systems being a big reason. From the conclusion of the report:
When drawing any conclusions about scope for improvement, the following points should be borne in mind: (a)differences in emission intensity may reflect differences in production systems that have arisen over time to enable the system to perform better within a given context, e.g. to make them more profitable, or resilient; (b) focusing on a single measure of efficiency (in this case GHG emissions per kg of output) can lead to positive and negative side effects on, for instance, biodiversity, water quality and animal welfare; (c) reducing GHG emissions is not the only objective producers need to satisfy, as they also need to respond to changing economic and physical conditions.
How Do Carbon Footprints Compare?
It is very important to note that when looking at data and numbers generated from different reports like these, the carbon footprints are difficult to compare unless they use the same LCA. Presenting carbon footprints from different LCA’s is an “apples to oranges” comparison. Only when the same LCA is used, can they be an “apples to apples” comparison.

In 2014, all man-made sources of greenhouse gas (GHG) emissions in the U.S. were estimated to be 6,870.5 MMT CO2e (millions of metric tons carbon dioxide equivalent). Agriculture was estimated to be responsible 8.3% of those emissions (573.6 MMT CO2e per year). When looking specifically at animal agriculture, all different species together emit an estimated 243.4 MMT CO2e/year, which is 3.5% of all U.S. emissions. The pork industry is estimated to have emitted 26.6 MMT CO2e or 0.34%. (Source: US EPA Greenhouse Gas Inventory 2015)
The two areas where the swine industry produced measurable contributions to agricultural emissions include:
Enteric fermentation – the release of gases during normal digestion by animals. Pigs release approximately 2.4 MMT CO2e of the of the 164.3 MMT CO2e produced by all livestock and poultry in the U.S.
Manure management – pig farms are estimated to release 24.2 MMT CO2e of the 78.7 MMT CO2e produced by all animal manure systems in 2014.
Manure management is planned using a total system approach. Animal manure management systems involve six basic functions: production, collection, transfer, storage, treatment and utilization. The first five out of those six make up the manure management number above. Utilization (usually by land application to crop fields) is instead categorized within “Agricultural soil management”. The greenhouse gases emitted from manure systems include methane and nitrous oxide which form as manure decomposes.
When all of the GHGs emitted during a particular activity or process are added together, it is the carbon footprint. The standardized procedure to calculate carbon footprints is a life cycle analysis or LCA.

The future of renewable energy and agriculture
This presentation discusses the overall energy needs of the U.S.and creative ways that energy needs can be evened out at grid-scale decision levels that involve very local (domestic water heater or electric car) ways to “store” excess energy and use it when needed. These types of decisions could reduce the needs for new power plant construction or need to bring a plant online for short periods of time for peak demand. As agriculture on on the “edges” of the grid, it could be part of the areas where change is likely to happen first. https://youtu.be/6QrXKOLmEZ8
