The Real (Sustainable) Superhighway?
Continuation of recent trends (middle of band) leads by 2100 to temperatures not reached since the Eocene (25-35 million years ago), when sea level was 20-30 m higher.

Sustainability is complex!
How do we measure sustainability?
Transport accounts for almost 40% of all UK exergy consumption
The consumption of exergy by air transport has increased by over 250% since 1970
Statistics are like a swimsuit:
what they reveal is suggestive, but what they conceal is vital
Road transport accounts for more than 70% of all transport exergy consumption
Road transport is more than fivetimes less efficient than rail transport
Transport accounts for more than 25% of all UK environmental impacts
Emissions from air transport have increased by more than 300% since 1970
Road transport accounts for more than 70% of all transport emissions
Road transport has 7½times greater impact on the environment than rail
What if we could travel by rail between
Edinburgh and Glasgow in 10 minutes
Dundee and Glasgow or Edinburgh in 20 minutes
Aberdeen and Edinburgh or Glasgow in 35 minutes
Edinburgh or Glasgow and London in 1½ hours?
Edinburgh and Glasgow would be a single city
Dundee would be a suburb of Gladinburgh or Edingow
The travel to work region of Aberdeen would encompass 4m people
Commuters could live in Gladinburgh and work in London
The City of Scotland would be the second largest in the UK and the fourth largest in Europe
It would have a tourist industry twice the size of London
It would have the second largest life sciences cluster in the UK
There would be a need for only one international airport
The UK centre of financial services might move to the City of Scotland
What if we could
step off a bus at every railway station in the City of Scotland
step off a train at the City of Scotland’s international airport
transfer freight directly from ships to trains?
reduce the amount of road traffic
increase our exports
reduce journey times
increase the number of tourists
reduce the amount of carbon emissions
made everyone pay the full cost of travel, including the cost of damage to the environment
made all public transport free
made it illegal to carry freight long-distance by road?
reduce carbon emissions at a stroke
need no new roads (or bridges!)
save enormous sums on road maintenance
reduce the need for petrol stations
make more friends?
If we always do what we always did, we’ll always get what we always got
The best way to create the future is to invent it
