This document summarises the compelling case for developing a New Zealand ‘Climate Policy Modelling Initiative’ (CPMI). This initiative would coordinate and enhance delivery of modelling across multiple providers. This work is informed by several workshops that brought together economic modellers from a range of organisations.

This paper presents a working model for New Zealand’s purchase of IERs, in which the quantity is controlled by government, purchasing is managed by government for the foreseeable future (with potential participation by private entities), and the quantity is factored into decisions on the NZ ETS cap and price management mechanisms.

This working paper, which evolved under Motu’s ETS Dialogue process from 2016 to 2018, explores key considerations for ETS cap setting and proposes the design for a cap on units auctioned and freely allocated in the NZ ETS.

This working paper, which evolved under Motu’s ETS Dialogue process from 2016 to 2018, explores key considerations for emission price management in the context of a specific working model for unit supply in the NZ ETS.

The drivers of land-use decisions are complex, and models provide a structured methodology for investigating these. For the public and private sectors to make robust land-use decisions under uncertainty, high-quality modelling tools and data are essential.
