Support the development, commercialization and deployment of technologies that lower enteric methane released by ruminants

These types of policy can also support the development, commercialization and deployment of technologies that lower enteric methane released by ruminant animals like cows, sheep and goats. Enteric fermentation is by far the biggest polluter in the agriculture sector, with a 6% share of global economy-wide emissions – equivalent to the EU’s total for all sectors. However, many of the existing climate solutions like feed additives and methane vaccines require government policy to kickstart deployment and reach commercialization. Some also need support to overcome challenges around delivering these solutions to livestock where they roam and graze over large areas. As well as financial incentives, governments can opt for policy sticks such as requiring livestock farmers that receive state subsidies to cut greenhouse-gas release or obligate feed manufacturers to incorporate methane-inhibiting additives in their products.
