The potential for using forestry offsets to meet University of Canterbury’s net-zero carbon emissions targets : a case study.

Abstract

The University of Canterbury (UC) has a strategic objective of being net carbon neutral by 2030. This case study has analysed the ability to meet this using forestry on UC’s high country properties and the framework of the NZ ETS to offset an estimated 6,525 tonnes CO2e annually from 2030.

Variations of three scenarios which facilitate carbon neutrality were investigated. The potential contribution from Mt Barker, UC’s only existing forest, was analysed under the assumption it was 1) retained and 2) cleared and replanted. In both cases complementary afforestation on UC Pastoral Lease properties was needed. A third scenario of new afforestation on UC pastoral land was also evaluated.

The results show that UC can achieve carbon neutrality. This can be facilitated at least cost using the forest at Mt Barker if the Corsican pine forest is retained and the additional eligible area entered into the ETS. However, for UC to maintain its status as net carbon neutral using forestry offsets, additional planting will be required. There are numerous programmes that UC could consider implementing to achieve this. If action is taken urgently, the estimated offset requirement of 6,525 tonnes annually can be met from 2030.
