Ralph has worked on climate change mitigation – ways to cut carbon emissions – since 1988, in the context of cities, transport, housing and urban planning. He’s also worked on environmental management and economics. He stepped down in 2021 after 16 years as Director of Environmental Studies at VUW. His current projects include the carbon footprint of public housing; and how to transition our cities to zero carbon.
Ralph's significant recent research studies include:
- The PHUR programme, addressing the outcomes of public housing provision for urban regeneration and wellbeing (current study, funded by MBIE’s Endeavour Fund).
- A research commission from the OECD on transitioning cities to zero carbon.
- The ACTIVE project addressing the impact of investment in walking and cycling infrastructure on encouraging active travel, and reducing car use (papers include a cost-benefit study; and a paper on overall intervention study results).
