On 13 November 2019 the Climate Change Response (Zero Carbon) Amendment Act received royal assent, writing 2050 targets and creating the Climate Change Commission.

Context

James Shaw as climate minister and National’s cross-party vote are on the file. Biogenic methane has a separate target. Implementation still needs later carbon-price and farm instruments. A Commission is not a coal-plant closure by itself.

Wellbeing Budget is 30 May. COP appearances are other dates.

A New Zealand prime minister chairs Cabinet and can recommend orders and bills. The House enacts. Police, DHBs, MIQ contractors, and platform companies implement. That office is not authorship of WHO guidance, Australian law, or a later successor’s repeal.

Why it matters

Decarbonisation-policy path from a completed target-and-commission statute.

What the sources establish

New Zealand Parliamentary Counsel Office carries the official instrument or communique. Reuters records the same dated act independently.

Established: The Zero Carbon Amendment Act 2019 was enacted.

Not established: A unique 2019 gigatonne coefficient from assent.

The House enacted. The Commission still writes advice. Farmers still emit.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies New Zealand enacts the Climate Change Response (Zero Carbon) Amendment Act 2019, not a later speech about New Zealand enacts the Climate Change Response (Zero Carbon) Amendment Act 2019.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to She sponsored a cross-party climate statute. The House enacted. The Commission still writes advice. Farmers still emit. That limit is the alternative to treating office-holding as authorship of every later series.
