Cows are being blamed for contributing to climate change through their farts and burps. I wondered, how do you even measure a cow burp? I called Erin Marlowe of Agri-Mark/Cabot Creamery Cooperative to explain. Erin is working with farmers across the Northeast to measure the total greenhouse gas emissions from their farms. She talks to me about how to measure a cow fart and also what farms can do (and are doing) to reduce those emissions with an industry goal of achieving net zero carbon emissions by 2050. Part of the climate solution can and should include bovines, and here's why.
