Analysis of 55 years of pig farming reveals gains in all key metrics.

America’s pig farmers continue to practice many of the principles of Earth Day, which is April 22, every day on their farms, and in many cases, have done so for generations. This fact is underscored by the results of a recent study from the University of Arkansas, which confirmed that today’s pork is more earth-friendly than ever thanks to great progress in multiple key sustainability metrics over more than five decades.
According to the new study, A Retrospective Assessment of U.S. Pork Production: 1960 to 2015, the inputs needed to produce a pound of pork in the United States have become more environmentally friendly over time. Specifically, 75.9% less land is needed, 25.1% less water and 7% less energy. This also has resulted in a 7.7% smaller carbon footprint.
To save as much water as today’s pig farms do over their predecessors of 50-plus years ago, the average American would have to take 90 fewer showers per year. Likewise, to understand the energy savings accomplished by pig farmers during the study period, a typical household would need to eliminate the use of a refrigerator altogether.
“The study confirms that U.S. pig farmers like me have been making progress in our ongoing commitment to do what’s best for people, pigs and the planet, which is at the heart of the industry’s We Care initiative,” says Steve Rommereim, National Pork Board president and a pig farmer from Alcester, S.D. “It’s encouraging to see this level of progress in environmental stewardship over the years. It also is helpful to have a benchmark to measure additional improvements.”

Unlike some earlier studies, the new Pork Checkoff-funded study used a comprehensive life-cycle assessment approach and the best available methodology along with a field-to-farm gate approach. This means including material and energy flows associated with the full supply chain, beginning with extraction of raw materials through production of live, market-weight pigs, including marketed sows.
