When it comes to climate action, Denmark has rarely been content to sit on the sidelines. Now, the small Nordic nation is taking another pioneering leap — becoming the first country in the world to implement a carbon tax on livestock emissions, set to begin in 2030. During a CLEAR Conversations podcast, which was filmed at the 2025 State of the Science Summit held at UC Davis, Anna Trillingsgaard from the Embassy of Denmark shared how this ambitious plan came to be and what it means for farmers, the environment, and the global agricultural community who is watching closely.

When it comes to talking about methane and cattle, few people can make the science sound both accessible and hopeful quite like Dr. Sara Place. A former UC Davis graduate student and now an associate professor of animal sciences at Colorado State University, Place has built her career around understanding how livestock can be part of the climate solution — not just part of the problem.

For over two decades, Dr. Mitloehner has been at the forefront of research on how animal agriculture affects our air and our climate. With deep expertise in emissions and volatile organic compounds, his work initially focused on air quality in regions like California’s Central Valley—home to both the nation’s richest agricultural output and some of its poorest air quality. In recent years, methane has taken center stage in climate discourse—not just scientifically, but politically. Once a topic reserved for technical discussions about manure management and feed efficiency, it has become a flashpoint in debates over sustainability, regulation, and even the legitimacy of livestock farming itself. Dr. Frank Mitloehner, Professor and Air Quality Specialist with the CLEAR Center sits down with Associate Director for Communications at the CLEAR Center, Joe Proudman.

UC Davis football will charge into their Big Sky Conference opener against conference rival Weber State, setting the stage for a night packed with excitement. With students back on campus, the energy will be electric—complete with the thrilling First-Year Field Storm, and a stadium full of Aggie spirit. Kickoff is expected at 7 p.m., but the festivities fire up well before then. At 5 p.m., join us for an ag-tastic tailgate that brings the farm right to the field. Back by popular demand, this pre-game showcase will feature cattle, sheep, goats, tractors, and more—turning the tailgate into a tribute to the roots that make UC Davis a leader in agricultural excellence. It’s a chance to honor the Animal Science Department and the College of Agricultural and Environmental Sciences, and to gather with friends, faculty, students, and supporters in a true Aggie-style celebration. “To see agriculture celebrated in such a high-energy, crowd-filled space like a football game is incredible," said Dr. Frank Mitloehner, director of the CLEAR Center. "It’s a reminder that farming isn’t just essential—it’s also deeply connected to our everyday lives. And this game brings that message to life in a way that’s fun and exciting and it will be a powerful tribute to the people driving agriculture forward.”

Hosted by CLEAR Center Director and greenhouse gas expert Dr. Frank Mitloehner, along with members of the CLEAR Center communications staff, the podcast will break down complex topics—like climate change, livestock emissions, and the future of food—into clear, relatable conversations.
