Agriculture-Generated Methane Needs to be Reduced to Meet Global Climate Change Target
Methane is a powerful greenhouse gas. According to the UN environment Programme, “over a 20-year period, it is 80 times more potent at global warming than carbon dioxide. Methane has accounted for roughly 30% of global warming since pre-industrial times and is proliferating faster than at any other time since record keeping began in the 1980s. In fact, according to data from the United States National Oceanic and Atmospheric Administration, even as carbon dioxide emissions decelerated during the pandemic-related lockdowns of 2020, atmospheric methane shot up.”
Enteric methane is the single largest source of direct greenhouse gas (GHG) emissions in the beef and dairy sectors, representing 2.5% of total U.S. GHG emissions. Microbes in the digestive system of four-chambered-stomach animals, called ruminants, like cattle and sheep, produce methane through the digestion of forages and concentrate feeds.
New approaches to livestock production are needed to lower the amounts of agriculture-generated methane to limit global warming to 1.5°C, a target of the Paris climate change agreement.
Why this research is important
To address this persistent environmental concerns, the Foundation for Food & Agriculture Research is awarding a $455,704 Seeding Solutions grant to Pennsylvania State University (Penn State) to reduce enteric methane emissions from ruminants using plant and fungal sources. Purina Animal Nutrition is providing matching funds for a total $914,543 investment. But it takes only about a decade for methane to break down. So, reducing methane emissions now would have an impact in the near term and is critical for helping keep the world on a path to 1.5
