Food has a critical role to play in the fight against climate change. By addressing both CO2 and methane emissions at farm level, Bel is a pioneer in the search for revolutionary solutions, committed to the 1.5°C trajectory which aims to limit global warming to below this threshold.
Methane is a potent greenhouse gas that has a much greater warming effect than CO2, and cows, by naturally emitting this gas during digestion, are the second-most important source of methane from human activities (after fossil fuels). But the feed additive developed by dsm-firmenich, Bovaer®, added to the dairy cows’ diet – no more than a quarter of a teaspoon per cow per day – can suppress some of the chemical reactions that produce the gas in their stomach, thus making them emit 25% less methane on average.
With the support of its partner farmers, Bel aims to deploy the solution to all 10,000 cows supplying milk in Slovakia. This will cut methane emissions by 1/4 for each farm and represent an overall yearly 400-ton methane reduction, or 11,000 tons of CO2 eq – the equivalent of taking over 3,300 family-sized cars off the road.
In line with its mission to champion responsible food, Bel thus aims to make its dairy products low methane. Deploying Bovaer® at scale demonstrates the Group’s and dsm-firmenich’s determination and pioneering spirit in the search for innovative, concrete, and effective solutions to combat climate change.
Simon Bonnet, Bel Group Milk Purchasing Director, says: “Deploying this revolutionary solution to our Slovakian dairy basin is proof that we are taking decisive steps towards a low-methane future for dairy. At Bel, we are incredibly proud to be able, together with our partner farmers, to bring innovative solutions and transform the agricultural model to make it more sustainable and responsible. After deploying in Central Europe, we aim to make low-methane milk a reality in other markets as well. We’ve carried out 900 carbon diagnostics at our partner farms, showing that methane emissions represent about half of the greenhouse gas emissions of a dairy farm – the potential for change is enormous.”
Mark van Nieuwland, VP Bovaer® at dsm-firmenich, adds: “At dsm-firmenich, our purpose is to bring progress to life, committed to pushing the boundaries of science and technology to make the world we live in more sustainable. Bringing new innovations to market is only possible with the support of pioneering players such as Bel Group. This large-scale deployment of our promising Bovaer® solution shows that the future of low-methane milk is here.”
This new feed additive has been the subject of scientific studies conducted by several research institutes and universities, including INRAE in France, Wageningen University in the Netherlands, and UC Davis in the United States. It is also validated by the European Food Safety Authority (EFSA). Bovaer® respects the well-being of cows, consumers and the environment. After acting to suppress methane production in the cow’s stomach, it is naturally broken down into elements already present and processed by the animal’s metabolism, without affecting production volumes or milk quality.
Once the roll-out is complete in Slovakia, consumers will be able to choose tasty, low-methane Babybel® products made in Bel’s Slovakian plant with 100% Slovakian milk and destined for Central Europe (Germany, Czech Republic and Slovakia) as well as the UK.
Bel is working to extend this low-methane solution to other Group markets. Pilots with Bovaer® are being carried out in France since early 2023.
 Methane is about 28 times more effective than CO2 at trapping heat in the atmosphere over a 100-year period.
 The results of the pilot experiment conducted by Bel in 2022 are very positive and show a potential reduction of on average 30% in methane emissions from cows, depending on their ration and the amount of Bovaer fed.
