New Zealand Climate Change Response (Zero Carbon) Amendment Act 2019
New Zealand's framework climate law, setting a 2050 net-zero target for long-lived gases, a split-gas methane target, and an independent climate commission.
Definition
The Zero Carbon Act, enacted in 2019 as an amendment to the Climate Change Response Act 2002, sets a target of net-zero emissions of all greenhouse gases other than biogenic methane by 2050, with a separate 24–47 percent reduction target for biogenic methane. It establishes emissions budgets, requires emissions reduction and adaptation plans, and created the independent Climate Change Commission.

Why it matters
It is the leading example of climate framework law adapted to a farm-heavy economy, closely watched by other agricultural nations.
