Mostly vehicles
10 million passenger EVs on the road today, along with more
than 500,000 e-buses, almost 400,000 electric delivery vans
and trucks and 184 million electric mopeds, scooters and
bikes. Growth rate 40% per year
13. Dramatic movements … `
• Most international vehicle manufacturers now producing or launching
lines of electric vehicles
• Costs sharply declining
• Growing number of countries
moving to set phase-out date for
sale of traditional vehicles
• UK set to announce tomorrow -
(20 Nov) bringing forward its ICE
phase-out date from 2040 to 2030

15. Shared Micromobility Trips Grew by 62%
in 2019
The number of micromobility trips grew
62% from 2018 to 2019 due to the large
increase in scooter trips. Shared
micromobility refers to small fleets of
fully or partially human-powered vehicles
including bikes, e-bikes, and e-scooters.
Trips on scooters more than doubled from
2018 to 2019 while bike trips increased by 3%
and e-bike trips increased 54%. Data collection
by the National Association of City
Transportation Officials (NACTO) began in 2010
and included only bike trips until 2018.
Note: Data includes systems with
over 150 bikes or scooters and
includes only data reported by
large cities. Data does not include
private or closed campus systems
like those operating on university
campuses. For more detail, see
the source report.

19. The ‘Dark Matter of macroeconomic growth’
• Macro-economic research points to two key areas of economic growth
in addition to resource & capital accumulation:
– Improving efficiency of many economic actors and structures throughout the
economic system
– Infrastructure, innovation and education
• ie. First and Third Domain processes are recognised as important for
macroeconomic development. Yet these remain
– largely absent in global (or national) modelling
– poorly charted in policy

Policy pillars
“The EU 3-targets
approach is
madness.. “
“Other policies such
as feed-in tariffs,
industry regulation
and subsidies, are
far less economically
preferable than
carbon pricing to
reduce emissions… “
(OECD, 2013)
I beg to differ …
Ideal policy comprises a package …
Key is to match the best instrument to the
respective domain of decision-making

24. Covid
• A huge macroeconomic shock
• A dramatic episode of ‘Schumpeterian Destruction’
• – can it be made a creative one?
• Keys will be:
– A clear and compelling narrative of the opportunities (and the risks)
– International financial cooperation (eg. underwriting)
– Synthesis between financial and energy/transport policies – Central Banks
need to care about how the money is used
– Links between the lending, infrastructure contracts, and environmental
revenue opportunities to underwrite 10-20 year payments
(eg. carbon pricing, road pricing)
25. 25
Sector policy still crucial to accelerating decarbonisation
`To overcome obstacles in international diffusion
‒ Country risk particularly in some developing countries create high cost of capital
‒ Some State-Owned Enterprises particularly in Asia still funding coal and sometimes impeding
renewables
‒ Challenges may be exacerbated by aftermath of Covid (impact on debt and attention to sectoral
reform)
To reform power market structures appropriate to ‘free to run’, variable output power sources
To provide the infrastructure of interconnection and electric vehicle charging
To help incumbent industries adjust
To promote both efficient use, and electrification of carbon-intensive end-uses

“.. Then took the other, as just as fair,
And having perhaps the better claim,
Oh, I kept the first for another day!
Yet knowing how way leads on to
way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and
I—
I took the one less traveled by,
And that has made all the difference.”
Robert Frost
