The Center for Quantitative Genetics and Genomics at Aarhus University is participating in a global initiative aimed at reducing methane emissions from cattle herds through natural breeding methods.
Some cows naturally emit less methane than others. This is the basis for a new $27.4 million USD (approx. 186 million DKK) global initiative focused on reducing methane emissions by selectively breeding animals that produce the least methane.
The Center for Quantitative Genetics and Genomics at Aarhus University has joined the initiative, which is funded by the Bezos Earth Fund and the Global Methane Hub. The initiative supports research and breeding programs designed to identify and measure climate-efficient livestock across North America, South America, Europe, Africa, and Oceania.
Researchers at the Center are actively involved in projects focused on the three major dairy breeds—Holstein, Jersey, and Danish Red—with the goal of improving methane efficiency in dairy cows. This work is particularly important for Danish dairy farmers, who face a carbon tax starting in 2030. In this context, selective breeding is seen as a scientifically grounded solution.
Cattle are the largest contributors to livestock-related methane emissions, but even within the same herd, some animals naturally emit up to 30% less methane than others. Researchers say that selecting and breeding these animals could lead to permanent reductions in climate impact.
“Reducing methane from cattle is one of the most elegant solutions we have to slow climate change,” says Dr. Andy Jarvis, Director of the Future of Food at the Bezos Earth Fund. “Thanks to our partnership with the Global Methane Hub, we’re supporting an effort that uses age-old breeding practices to naturally identify and promote low-emission cattle—ensuring climate benefits for generations to come.”
Over time, this approach could reduce methane emissions from cattle by 1–2% per year—amounting to a 30% reduction in the long run.
