Decarbonising Urban Mobility with Land Use and Transport Policies

The Case of Auckland, New Zealand

image of Decarbonising Urban Mobility with Land Use and Transport Policies

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.


Data and model calibration in the Auckland case study

This chapter provides a navigation of the various data sources and presents the model calibration. The first section describes the data sources, which include a travel survey conducted in New Zealand, geo-spatial data, New Zealand fleet registration data and Google API data on travel times. The chapter describes and visualises how land use and travel survey data are combined to create a stylised representation of residential and employment locations in Auckland. The second section, provides detail on the calibration of the model including the way households spend their income and allocate their time, as well as their travel behaviour and its elasticity to price and income changes. These values are important as they provide evidence of the adaptation of MOLES to Auckland and a link to the general empirical regularities reported in the literature.
