The third and final workshop in our Shared Mobility series with CoMoUK

1. Professor Greg Marsden
Institute for Transport Studies
University of Leeds

2. Carbon Realities
• Whole life emissions that
matter
• BEV2030 is ~ 50% ICEV
2012*
• 150,000 mile vehicle life
• Size of fleet matters hugely
• If fleet grows to 40m then
emission savings all BEV by
2030 are around 25%
*The exact figures can be
debated but not the problem

3. Massive opportunities
Max = 14% Max = 8%

5. Crunch time
• There is not a world with 37-40.5million cars where shared mobility has worked
• There is not a world with 37-40.5million cars where the carbon trajectory was
close to being met
• Embodied emissions
• Growth before greening
• Infrastructure demands
• Inefficiency
• What does it take to deliver a credible, widespread alternative to the individual
car ownership model?

space
Equity of
access

10. Choice of mode for the trip

11. Current scale – car clubs
Circa 550,000 members in the UK (pre-
Covid)

12. Market potential – car clubs
London
• 650,000 households able to give up a car; 260,000 fewer
privately owned cars
Scotland
• 634,000 households able to give up a car; 192,000 fewer
privately owned cars
Roughly this was on the back of doubling the size of the car club
fleet.

13. Future scale – car clubs
• Germany is already at c. 2 million car sharing users
• Adjusting for population size gives a UK equivalent total of c. 1.5 million users (so we are 1
million adrift currently)
• Using c. 550,000 members and c. 5,300 cars as a base, and a multiple of 50 members per
car (much higher in London – 94) we get to needing 20,000 car club cars to reach where
Germany is now.
• In 10 years' time we need to have gone much further – the CTD finding of 55% traffic
growth in more individualised growth scenario vs 5% in a more shared scenario

14. What would the UK look like?
• Sharing options in the mainstream in any sizeable settlement (say over 50,000
population);
• Mobility hub networks well established in majority of major conurbations plus
some rural areas;
• Equity mitigations framework;
• Government's transport spending, assessment, framework setting, market
incentivisation etc. all re-prioritised through GHG lens
• Reduce/reuse/recycle: reduce transport demand; reuse what we have already as
efficiently as possible/accept but reform the role of cars
