Why is change needed?
Inefficiency
• Energy use per capita for road transport is 20% above OECD average
• High proportion of private car use
• High energy use per tonne-km in freight
• Depressing productivity
Emissions
• Particulate emissions
• GHG emissions from road transport

Drivers of change in transport – global factors
1. What is happening globally that might shape NZ’s future transport?
2. How NZ could respond to / take advantage of these opportunities?

Research process
Delphi: An iterative, multi-stage process, bringing together expert opinions on complex topics
Panel of invited experts: (all international but 3)
Academia (n=18), industry (n=3), government (n=4), consultancy (n=3), NGO (n=1), other (n=1).
Fields of expertise included: renewable energy, transport policy, demand modelling, material technology, freight, transport economics, behaviour

Next step ... NZ Delphi
How might NZ respond to these circumstances? What could NZ’s future transport system look like?
