The Climate Change Response (Zero Carbon) Amendment Act 2019 signifies a landmark shift in New Zealand’s legislative landscape, introducing a comprehensive framework aimed at tackling climate change while aligning with global commitments under the Paris Agreement to limit the rise in global average temperature below 1.5˚ C from pre-industrial levels. Central to its efficacy are ambitious emission reduction targets, including achieving net zero emissions for all greenhouse gases except biogenic methane by 2050, along with specific targets for biogenic methane reduction by 2050 and interim goals for 2030. These targets provide a clear path for emissions reduction, offering a structured approach to tracking progress and guiding policy interventions.
