New resource to help dairy industry clean up the Chesapeake Bay

It’s a tough time to be a dairy farmer. Nationwide milk prices are at record lows due to an oversupply of milk and changing consumer preferences, and the industry faces increasing public and regulatory pressure to reduce greenhouse gas emissions and improve water quality. These challenges hit home for the dairy industry in the Chesapeake Bay region.

Pennsylvania, Maryland and Virginia cannot meet U.S. EPA-mandated water quality goals without an all-hands-on-deck effort that includes dairy cooperatives, processors and farmers. This increases the pressure on the dairy industry, but it also creates an opportunity for the sector, with support from partners and other stakeholders, to show leadership.

A new open-source sustainability guide [PDF] provides a roadmap for the dairy industry to improve water quality and foster economic and environmental resilience at a critical moment. Read More »

Americans’ fondness for milk, yogurt, cheese and juicy burgers requires a huge livestock industry, with nearly 90 million head of cattle in the U.S. in any one year. All those cows mean significant methane emissions.

With estimates from the United Nations that methane accounts for 44 percent of all greenhouse gas emissions from livestock production, and new determination – including legislation in California – to reduce methane emissions from farms, we need to figure out how to quantify and then reduce those emissions.

Yet measuring methane emissions has been an elusive science. Methane is a colorless, odorless gas that packs a powerful punch: Methane has 84 times the global warming potential of carbon dioxide in the short term. Read More »
