Methane (CH₄) is a powerful greenhouse gas produced during the digestion process of ruminants. As cows digest feed in the rumen, they produce methane, which is released into the atmosphere through belching. Although methane has a shorter lifespan than CO₂, it has a much stronger warming effect. Reducing methane emissions therefore directly contributes to combating climate change and helps the dairy sector achieve its sustainability goals.

Following years of research—through the Climate Smart Cattle Breeding project by CRV, Wageningen University & Research (WUR), and FrieslandCampina, co-funded by the Dutch Ministry of Agriculture, Nature and Food Quality—a solution has been found to permanently reduce methane emissions from cattle. It turns out that it is possible to breed for a herd that emits less methane. That’s why the cooperative CRV has introduced a methane breeding value, based on measured differences between no fewer than 14,000 cows. This gives dairy farmers a great opportunity to contribute to slowing down global warming.

Breeding for methane reduction can provide several advantages for your dairy farm:

• Produce more sustainably: Breeding for lower methane emissions reduces environmental impact without additional investments.
• Be future-ready: Sustainability requirements are becoming stricter. Taking steps now helps you stay ahead in the sector.
• Dairy processors and retailers: Are increasingly looking for ways to reduce the carbon footprint of milk. By breeding for methane reduction, you align with a broader trend toward more sustainable milk production—something that can help strengthen your farm’s economic position.
