Methane-cutting supplements for cows: 10 Breakthrough Technologies 2025

Meanwhile, startups like Blue Ocean Barns, Romanian8and Symbrosia are developing, testing or seeking approval for products derived from a species of red seaweed that could reduce methane levels even further. However, other organizations are trying to solve the problem in more long-term ways, through vaccine development or changing microbes in the intestines of cattle.

It remains to be seen how much livestock farmers will pay for such products. But in the case of Bovaero, farmers who use it can earn greenhouse gas credits that some companies will buy in voluntary carbon markets as a way to reduce their corporate climate footprint. according to Elancowhich sells the additive in the USA. Meanwhile, Rumin8 says that cattle that take his supplements could produce more meat and milk.

Additives certainly do not solve the whole problem. The cattle industry must take other big steps to reduce its climate emissions, including stopping the encroachment of carbon-absorbing forests. And to really reduce demand, food companies will have to develop better, cheaper, cleaner alternative products, like plant-based burgers and milk substitutes.

But methane-reducing additives are increasingly looking like a promising way to solve a big part of a very big problem.
