Abstract: Considerable uncertainty exists about future fuel prices and carbon costs, with different trajectories for these variables having significant potential impacts on New Zealand agriculture. This paper explores the impacts of a range of possible changes in fuel and carbon prices on New Zealand’s key agro-food sectors, particularly dairy, beef and sheep. We use the latest version of the GTAP-E model (Corong et al., 2019), based on the well-known Global Trade Analysis Project model (GTAP) (Hertel, 1997; Corong et al., 2017). This model enables us to capture inter-sectoral linkages within New Zealand as well as internationally, along with a relatively detailed specification of energy inputs and associated carbon emissions. To enable detailed analysis of key livestock sectors, we split the GTAP beef and sheep (i.e., “ctl”) sector. We use the latest GTAP version 10 Data Base, including carbon dioxide emission data distinguished by fuel type and user, supplemented with the GTAP non-carbon dioxide emissions data on other greenhouse gas emissions. This research is part of a larger study that explores the energy and carbon costs of New Zealand livestock agro-food products through their life cycle to overseas markets; we draw on data on energy use and emissions from this wider study to augment the New Zealand data available in the GTAP-E and non-carbon dioxide databases. We model a range of scenarios, making different assumptions on future fuel prices and carbon costs. In particular, we consider low, moderate and high increases in these prices to explore different impacts on both global and New Zealand economies. We also explore potential trade diversion and carbon leakage effects if New Zealand were to impose carbon taxes unilaterally, as opposed to a global carbon tax policy.
