Summary

At COP28, “3 degrees of change” was introduced as an idea to reduce the environmental impact of the global frozen food system. For New Zealand, where food exports represent a significant proportion of the GDP, and global isolation creates a need for energy self-sufficiency, this potential change represents a rational opportunity. Refrigeration is the 4th highest industrial user of energy in New Zealand, estimated at 15% of the national energy usage. Much of the work to-date and contemporary studies consider the food quality implications of a -15 °C temperature. In this work, we explore the structural, legal, relationship and commercial barriers and opportunities to implementing the temperature change in the New Zealand context. This is considered in the context of both domestic food supply and international trade. We find that there are many actors with differing requirements, considerations and risks to manage that will need to align for a new temperature standard to be implemented.
