All told, agriculture accounts for approximately 10% of total U.S. greenhouse gas (GHG) emissions, far less than the transportation, electricity generation, and industry sectors. Farmers continue to produce more with greater efficiency. In fact, U.S. agriculture would have needed nearly 100 million more acres 30 years ago to match today’s production levels.
Carbon sequestration, achieved through the management of forestry, grasslands, wetlands, cropland and settlements, contributed to GHG removals equivalent to 12% of total U.S. emissions. With increased investment in agricultural research, we can develop new frontier technologies to reduce emissions and capture even more carbon. With cutting-edge science, we may be able to achieve net zero emissions in some sectors of agriculture.
U.S. farmers and ranchers have long been at the forefront of climate-smart farming, utilizing scientific solutions, technology, and innovations to raise crops and care for livestock. These efforts are designed to protect soil and water, efficiently manage manure, produce clean and renewable energy, capture carbon, and improve sustainability. Over two generations, we’ve nearly tripled our productivity, without using more resources. To say we’re doing more with less is an understatement.
Many of agriculture’s carbon sequestration efforts are not directly assigned to the agriculture sector. It is certain that if the carbon sequestration efforts of U.S. farmers and ranchers were assigned to agriculture, our contributions to GHG emissions would be lower. It is worth noting that U.S. farmers have enrolled more than 140 million acres in federal conservation programs--that’s equal to the total land area of California and New York combined. Millions more acres are dedicated to nonfederal conservation programs.
More productive livestock operations allow ranchers, pork producers, poultry growers, egg producers, and dairy farmers to maintain their total contribution to GHG emissions at less than 4%. Innovation plays an important role, from methane digesters to advances in nutritional balance that lead to lower per-unit GHG emissions. In fact, we have seen a 26% reduction in per-unit emissions of GHGs for our dairy industry while milk production is up 48%, a 20% reduction in swine with an 80% increase in pork production and close to a 10% drop for our cattle producers with an 18% increase in our production of beef.
U.S. farmers and ranchers contribute significantly fewer GHG emissions than their counterparts around the world. EPA data shows agriculture’s global contribution to GHG emissions was 24% in 2010, more than double U.S. farmers’ and ranchers’ contributions to total U.S. emissions in 2020. This significant difference is largely driven by U.S. farmers’ enthusiastic adoption of technology. American farmers and ranchers are pioneers of sustainability, and any policy debate should recognize their contributions, efficiency gains, and the considerable impact of their carbon sequestration efforts.
