Abstract: Purpose - – The authors aim to investigate the ability of a New Zealand university to rely on the CO2sequestered in the trees on campus to mitigate the CO2emissions caused by operations. Design/methodology/approach - – The authors count and measure the trees on the university's 68 hectare main campus, ignoring smaller trees that sequester very little CO2. Findings - – The authors estimate that the 4,139 trees the authors count contain 5,809 tonnes of CO2. The authors further estimate the additional CO2sequestration over the next ten years to be 253 tonnes per year. The university's annual CO2emissions were 4,086 tonnes in 2011. More than 70 per cent of this amount relates to overseas travel. Therefore, CO2sequestration in trees promises to mitigate only about 6 per cent of total emissions over the next ten years. Practical implications - – This suggests that other initiatives will be needed if the university is serious about reducing its greenhouse gas emissions impact. An obvious avenue appears to be to reduce overseas travel, e.g. by finding different ways for academic staff to network and obtain feedback on their research. Other universities and other organisations starting to investigate their environmental impact are likely to similarly find that CO2sequestration in trees can only provide limited mitigation opportunities. Originality/value - – The authors contribute to the ongoing debate around carbon emissions, exploring avenues to mitigate CO2emissions.
