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 part of tackling climate change.
