New Zealand is unusual among developed nations in that a high proportion – nearly half – of its greenhouse gases come from agriculture. Most of these emissions are methane from burping farm animals, and nitrous oxide from soils and fertilisers. According to estimates published in the 2019 national Greenhouse Gas Inventory, total emissions in 2017 were 23% above 1990 levels. This cow is being monitored for gas emissions.
