Investigating the direct and indirect environmental pressures of New Zealand's food and fibre industries


The production and processing of primary products has been the foundation of the New Zealand economy for 150 years. However, the economic benefit gained from the food and fibre industries has come with associated environmental costs. While the producer-centric approach is the prevalent way of viewing environmental pressures from production, consumption decisions also have an influence on environmental outcomes.

From a production perspective, the food and fibre industries analysed herein together appropriated approximately 30% of New Zealand's energy, 88% of economically available land, and 46% of the nation's total potential. When environmental pressures are assigned by consumption categories, households in New Zealand appropriated 24% of land used in domestic production, 52% of energy, and 43% of GWP. Exports appropriated 67% of land use, 35% of energy, and 52% of GWP. The remainders were appropriated by Other Final Demand.

A synthesis of carbon in international trade

In this comprehensive and up-to-date overview of the analysis of carbon embodied in international trade, Glen Peters and colleagues bring together treatments of some of the key issues, and introduce important new analyses. Learn more »

Approximating MRIO

Because of the cost and perceived difficulty of using full multi-regional input–output (MRIO) models to calculate emissions embodied in international trade, many researchers use simpler approaches, making key assumptions and approximations. In this study, Robbie Andrew and colleagues investigate the effects of these approximations and provide advice on their use. Learn more »

Sharing responsibility

The two prevalent approaches to allocating responsibility for greenhouse gas emissions – production and consumption perspectives – push responsibility to either end of the supply chain. In this study, Robbie Andrew and Vicky Forgie present the first national-level application of the shared responsibility perspective. Learn more »
