Cornell University unveils a $2 million respiration chamber facility to measure methane emissions from cows and explore the effectiveness of feed additives in reducing dairy industry emissions.
Cornell University has unveiled a groundbreaking $2 million facility designed to tackle one of the dairy industry’s most pressing environmental challenges: methane emissions. Situated on the university’s campus in Ithaca, New York, this state-of-the-art research center features four advanced respiration chambers that provide unprecedented data on cow emissions.
The facility’s primary focus is to analyze the methane produced by cows, a significant contributor to climate change. Methane from livestock accounts for over one-third of global methane emissions, with agriculture in New York alone responsible for approximately 6% of the state’s total greenhouse gas emissions.
The respiration chambers are uniquely equipped to measure the precise amount of methane each cow emits, offering crucial insights into how feed additives might reduce these emissions. The research aims to identify effective additives that can lower methane output without compromising the cows’ health or productivity. Feed additives such as seaweed, oregano, and engineered powders have shown potential in preliminary studies, but no additive has yet been found to completely eliminate methane production.
Joseph McFadden, Associate Professor of Dairy Cattle Biology at Cornell, emphasized the urgency of reducing methane emissions and the facility’s role in providing accurate, detailed measurements essential for improving feed additives.
“Now to actually have this equipment, it gives us a tool to be able to ensure that we have accurate measurements,”

The facility’s opening is part of a broader effort to address climate change through agricultural innovation. With the Biden administration and other countries investing heavily in climate-smart agriculture, Cornell’s research could play a pivotal role in shaping the future of dairy farming. However, some experts, like Eric Toensmeier from Project Drawdown, caution that while feed additives are a promising avenue, reducing overall meat and dairy consumption remains a crucial strategy for mitigating emissions.
Keith Kimball, a cattle farmer and Chair of the Northeast Dairy Producers Association, expressed cautious optimism about the potential of feed additives. “I am excited to see where it goes,” Kimball said, “But is it going to make us more efficient as an industry and improve our carbon footprint? I’m not positive that it is.”
As research progresses, Cornell University’s new respiration chambers stand at the forefront of efforts to make dairy farming more environmentally friendly, potentially offering solutions that balance productivity with sustainability.
