A recent study by AgResearch, as reported by Beef + Lamb New Zealand, reveals that New Zealand's beef and lamb have one of the lowest carbon footprints in the world. The carbon footprint of New Zealand sheep meat is approximately 15 kg CO2 equivalent emissions per kilo, and that of New Zealand beef is about 22 kg. The research finds that the total carbon footprint of New Zealand red meat is less than or similar to that of red meat produced in other countries when exported, due to New Zealand's farm-level efficiency. Eating red meat 2-3 times a week for a year contributes slightly more to the carbon footprint than a one-way flight from Auckland to Christchurch.
