LONDON - Methane-catching devices could be fitted to British cows to reduce emissions of the powerful greenhouse gas.

A company called Zelp has been working with one of the UK’s largest meat producers to trial the devices that help cut the carbon footprint of herds.

The device, which sits around the animal’s head, captures methane, which then travels through a micro-sized catalytic converter and is released into the atmosphere as carbon dioxide and water vapour.

The invention has the backing of Prince Charles, who described it as “fascinating”, according to The Telegraph.
