Achieving net-zero carbon emissions in New Zealand

Project code: BUS001

The New Zealand government has proposed to achieve a net-zero carbon target by 2050. Agriculture contributes to more than 50% of New Zealand’s GHG emissions. To date there appears to be minimal scope for reducing methane emissions from livestock. Fossil fuel based energy sources contributes to around 40% of total GHG emissions. Greater opportunities to reduce GHG emissions are possible with sector-wide improvements in energy efficiency, structural change, and electrification of transport.


  1. Explore, and quantify where possible, factors that influence energy-related GHG emissions in the NZ economy
  2. Identify feasible ways to reduce GHG emissions
  3. Recommend policies that could achieve the net-zero target.

Methods: Structural Decomposition Analysis (SDA), Index Decomposition Analysis (IDA), Penalized panel quantile regression, regression-based Shapley decomposition.

Anticipated outputs from the student: The student will assist with the literature review and data analysis. The student will produce a written report on research findings.
