This piece, written by Adele Peters, explains how a new feed supplement can decrease the amount of greenhouse gases burped out by cows.

Verra recently approved this methodology, developed by Swiss agritech company Mootral. The company’s product adds garlic and citrus to pellets that are mixed in with cow feed. The supplement changes the digestive process, without harming the cow, in a way that decreases the methane in the cow’s belches. Mootral will soon be issued the world’s first carbon credits for methane reduction in cows.
