The largest city in New Zealand, Auckland is home to roughly 1.5 million
people -- one third of New Zealand's population. Here we assemble a
bottom-up inventory of Auckland's fossil fuel carbon dioxide emissions
from a variety of data sources. We use these emissions estimates in
combination with the UrbanVPRM land surface model to estimate the net
carbon balance of the region. This work is part of the larger
CarbonWatch NZ project, which aims to produce estimates of New Zealand's
net carbon balance quickly enough to assess and refine ongoing national
efforts to reach carbon neutrality.
