New Zealand Climate Change Response (Zero Carbon) Amendment Act 2019
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.

Overview
What it means
New Zealand legislated a distinctive split-gas approach reflecting its agricultural emissions profile, with UK-style budget governance.
How it is used
Government sets budgets with commission advice; agriculture negotiates methane pricing under its shadow; courts cite it in policy challenges.
Why it matters
It is the leading example of climate framework law adapted to a farm-heavy economy, closely watched by other agricultural nations.
