DSM files for EU authorisation of new methane-reducing feed additive




Royal DSM has commenced filing for EU authorisation for a new feed additive for dairy cows that will reduce methane emissions by about 30% and thereby significantly reduce the environmental footprint of milk and dairy products.

The feed additive is scientifically proven to cut methane emissions from dairy cows by about 30%, with its efficacy confirmed in 26 peer-reviewed studies globally. Methane is a greenhouse gas, more potent than carbon dioxide, which contributes to climate change. Reducing global methane emissions could therefore help lower the rate of global warming in the near term, helping society stay within the 1.5-2°C maximum temperature rise indicated in the Paris Climate Agreement, while society moves to net zero carbon emissions.


Just a quarter teaspoon of the feed additive per cow per day suppresses the enzyme that triggers methane production in a cow's stomach. Upon feeding, the additive takes effect immediately. After suppressing methane production in the stomach, it is broken down into compounds already naturally present in the cow's stomach.


The feed additive is a result of DSM's decade-long Project Clean Cow in research and development. DSM says it is the most extensively studied and scientifically proven solution to the challenge of burped methane to date.


"We're excited to start registration in Europe," says Mark van Nieuwland, program director at DSM. "This is an important milestone. Our science-based solution has the potential to be a real game-changer in the global effort to reduce the climate impact of the foods we know and love. Because of its global warming potency, mitigating methane emissions will be a powerful lever for the diary sector to take action on the climate emergency.


DSM's feed additive will be available in Europe as soon as EU authorisation is granted, with a launch in the region anticipated in the late 2020 or early 2021 timeframe. Registrations in other regions will follow.
