Economic Impact of New Zealand's Second Emission Reduction Plan

This report uses CGE modelling to estimate GDP, employment and distributional impacts of the Emissions Reduction Plan 2 (ERP2), which delineates Aotearoa New Zealand's strategy to attain its emissions reduction objectives for the 2026-2030 period, alongside setting a path towards achieving long-term emissions reduction objectives.

EconAI
Toolkit Description
EconAI is our AI toolkit for economic policy and research delivery. It is designed to accelerate high-quality analysis by combining language-model capability with trusted evidence, project context, and transparent reasoning. EconAI supports tasks such as literature synthesis, drafting, comparison of policy options, and structured interpretation of complex technical material.
The key difference is control over information quality. EconAI is built to work from curated sources—internal reports, project folders, and structured libraries—rather than relying on uncontrolled web content. This improves reliability, reduces hallucination risk, and makes outputs easier to audit in a policy environment.
Technical Details
EconAI uses a retrieval-based workflow that grounds responses in a defined knowledge base and returns outputs with clear source attribution. The system is designed for secure deployment, with configurable knowledge sources (project folders, reference libraries, and approved web search where appropriate) and structured prompts aligned to policy writing and technical reporting.
Links
Use Case Examples
A project team preparing a Cabinet submission uses EconAI to synthesise international evidence on a proposed intervention, extract key effect sizes and conditions from technical studies, and draft a structured options section. The team then refines the narrative, while retaining an auditable trail back to the underlying sources.
