How Can Pig Farms Reduce Carbon Footprint?

Animal Manure Management July 28, 2016 Print Friendly and PDF

green stylized pig logoEven though pig farms are not a large source of greenhouse gases (GHGs), the pork industry (along with many agriculture industries) are looking at GHG emissions to identify areas for improvement

When carbon footprint is reported, you may see numbers that reflect the total GHG emissions for the entire industry or for individual farms. Sometimes you will see it reported in terms of GHGs emitted per pound of pork produced. This is a very appropriate way to examine an industry's improvements over time as it standardizes the number against changes in number of animals, number of farms, etc.

There are several areas being researched as ways to reduce GHG emissions:

A National Pork Board report on the total production cycle showed that selection and planning of manure storage systems represents the biggest opportunity for reducing the carbon footprint of a farm. Manure emits methane and some nitrous oxide as it decomposes. Both of these GHGs, especially nitrous oxide, are more potent than carbon dioxide in their ability to trap heat.

The video below, by Rick Ulrich, University of Arkansas provides a summary of different areas that are being studied to develop a tool for pig farms on reducing environmental footprint.
