The burps and farts of farm cows around the globe are a major contributor to methane pollution, with the average dairy cow producing about 98kg of methane annually.
For decades, scientists have been working on a methane-reducing vaccine for cows with little success, until now. A prototype vaccine by US-based start-up Arkeabio is showing promise following a trial with 10 cows that saw emissions drop by nearly 13 percent. It targets the methane-producing bacteria that lives in the bovine digestive system.
Arkeabio founder and CEO Colin South joins the show to discuss the vaccine and how it works.
