The report presents an in-depth analysis of various policies that aim to reduce the
greenhouse gas emissions of urban transport. Decarbonising transport lies at the core
of efforts to mitigate climate change and has close links to urban sustainability
and housing affordability. The report identifies the drivers of rising emissions in
the urban transport sector and offers pathways to reduce them through a combination
of transport and land use policies. The analysis yields a holistic welfare evaluation
of these policies, assessing them according to their environmental effectiveness,
their economic efficiency and their impact on fiscal balance and housing affordability.
The report concludes that significant reductions in emissions from urban transport
can be achieved through a careful alignment of transport policies designed to promote
the use of public transit and electric vehicles, and land use policies, which foster
a more compact urban form. The study is based on the case of Auckland, New Zealand
but the lessons drawn are relevant for institutions and governments working on issues
relating to urban sustainability, transport, housing and climate change mitigation.
