Dunedin's emissions profile
To explore how much Ōtepoti Dunedin needs to reduce emissions by to become a Zero Carbon city, a ‘baseline year’ has been used – the year against which progress is measured. For Ōtepoti Dunedin, the baseline year is 2018/19.
In the 2018/19 year, activities in the city generated 1,697,0002 tCO2e gross emissions, and forests absorbed 361,300 tCO2e. The DCC measured the city’s emissions again in 2021/22, and gross emissions had reduced by 9% despite the population having increased over the same period. In 2021/22, about half of Ōtepoti Dunedin’s emissions came from agriculture (46%), followed by transport (34%), stationary energy use (12%), waste (6%), and industrial processes and product use (IPPU) (2%).
