The world is warming. Since the Industrial Revolution the world’s temperature has increased by 1.1°C. Already we are experiencing the effects: more, and more extreme, droughts and floods; sea level rise; retreating snow and ice packs; changing crop viability.
The problem is over-production of three greenhouse gases: carbon dioxide, nitrous oxide, and methane. In 2020, methane accounted for 43.5% of Aotearoa New Zealand’s total greenhouse gases, and almost 90% of that came from agriculture. (MFAT – Aotearoa New Zealand’s Methane Emissions Reduction Action Plan). Reducing methane will help to rapidly mitigate short- to mid-term climate change.
New Zealand has committed to reducing biogenic (from agriculture and waste) methane by 10% below 2017 levels by 2030, and by 24% to 27% by 2050.
