22 Jul 2019 --- Netherlands-based Royal DSM has filed for the EU authorization of its feed additive, which reduces dairy cows’ methane emissions by 30 percent. The company states that just a quarter teaspoon of the additive per cow each day will significantly reduce the environmental impact of dairy products. A cow’s methane production accounts for over half its environmental footprint. The additive will be available in Europe once the EU authorization is granted – potentially in late 2020 or early 2021 – with registration in other regions to follow.
