There’s no such thing as easy climate fixes, but when it comes to methane emissions from oil and gas production, a couple of little patches could go a long way.

Humans aren’t the only ones experimenting with wearable smart masks. A Bloomberg report says agricultural giant Cargill will start selling masks for cows that can cut methane emissions from their burps.

The mask was developed by Zelp Ltd, a UK startup that claims its device can cut methane emissions by up to 53% in trials. It’s sort of like a car’s catalytic converter. According to Bloomberg, the mask features solar-powered fans that suck up the burps into a methane-absorbing filter. The filter then turns the methane into carbon dioxide, which is then released into the air. On Zelp’s site, it says the mask is purportedly adjustable, easy to install, and is similar to “normal halter[s] or collar[s].” The device is also designed to work for four years continuously without the need for charging, as it also features a solar cell and thermoelectric generator.
