This law establishes a climate change commission in New Zealand as well as a framework to regulate its activities. It enshrines into law the country's 2050 net zero target, and includes provisions to plan both mitigation and adaptation actions.
The targets require gross emissions of biogenic methane to reduce to at least 10% below 2017 levels by 2030 and to at least 24 to 47% by 2050. Emissions of all other greenhouse gases must reach net zero by 2050.
