A single dairy company is on track to add tens of thousands of tons of climate pollution to Minnesota's air — and state regulators aren't required to stop it.

Riverview LLP, the second-largest milk producer in the U.S., wants to nearly double its dairy near Morris, Minnesota, growing it to almost 19,000 cows. That expansion alone would add more than 66,000 tons of greenhouse gases a year and create over 200 million gallons of manure and wastewater annually. Riverview is building at this scale across the Midwest, with facilities in North Dakota and South Dakota holding 12,500 to 25,000 cows each — a scale most Minnesota dairy farms never approach, since over nine in ten operate with 500 or fewer cows.

Agriculture is already Minnesota's second-largest source of climate pollution, responsible for 96% of the state's nitrous oxide emissions and 44% of its methane emissions. "We are not just talking about big — we're talking about hundreds of times bigger than the average," said Sean Carroll, policy director at the Land Stewardship Project. Yet Minnesota's environmental review process treats emissions estimates as informational, not as enforceable limits a company actually has to meet.

Nearly 1,400 people have already submitted public comments raising concerns about the Morris expansion, and environmental groups have filed lawsuits arguing regulators are ignoring the climate math. The Minnesota Pollution Control Agency is expected to decide on the permit this June, and it still has the power to make real emission reductions a binding condition of approval, not just a suggestion.

Minnesota can't meet its climate goals while letting mega-dairies expand pollution unchecked. Sign the petition to demand the Minnesota Pollution Control Agency require enforceable emission limits before approving the Morris dairy expansion — before more climate pollution is locked in for good.
