Catching cow burps in real time: Methane sensor matches industry monitor in early field test
Methane is a short-lived but powerful greenhouse gas; cutting methane emissions can slow near-term warming and improve air quality by reducing harmful ground-level ozone. As ruminants digest feed, they release methane—through burps. In fact, emissions from cattle are the largest source of human-caused methane emissions (roughly 25% of the total)—so reducing emissions from cattle is an important…
Methane, a potent greenhouse gas, is emitted in significant quantities by cattle, accounting for roughly 25% of human-induced emissions. Reducing these emissions is a crucial aspect of addressing climate change. To validate cutting-edge methane sensors developed by Harvard University researchers, a test was conducted in collaboration with the University of California, Davis.
The GRAZE-Tag, a low-cost methane sensor designed to monitor cattle burps, was successfully tested against the industry-standard GreenFeed system. Early results showed the new sensor accurately detected methane emissions in cattle, indicating its potential to revolutionize real-time, low-cost methane monitoring on farms.
