A sustainable agriculture company has manufactured a device they say will help curb global warming by neutralizing methane exhaled by cows.

Zelp, a company based in London, says that its device can help contribute to a "strong reduction in the global warming potential of methane."

The mask, which is strapped to the snouts of cows, "neutralises methane exhaled in real time," the company claims.

The device also has digital monitoring technologies such as geolocation and emission monitoring capabilities.

Activists have warned that cows are significant contributors to global warming due to their regular emission of methane, including in the form of burps. Methane from cattle "contribute[s] nearly 10% of greenhouse gas emissions worldwide when measured over 20 years," Zelp argues.
