The Real (Sustainable) Superhighway?

1. The Real (Sustainable) Superhighway?

2. What’s Sustainability? Sustainability Enviro- Economic Environmental Socio- Environmental Economic Social Socio- Economic Sustainability

3. 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. A2 B1 Why is environmental sustainability important? Source: Professor John Holdren, Harvard University

9. Sustainability is complex!

10. Health Warning! • My (not so) secret weapon is ignorance • Accuracy has been sacrificed on the altar of simplicity

11. How do we measure sustainability? • Exergy is the part of energy that is useful to society • It is calculated from a knowledge of the chemical composition of compounds • Can be used to measure both resource consumption and the environmental impacts of emissions • Can add together the effects of different pollutants

12. Transport accounts for almost 40% of all UK exergy consumption

13. The consumption of exergy by air transport has increased by over 250% since 1970

14. Statistics are like a swimsuit: what they reveal is suggestive, but what they conceal is vital

15. Road transport accounts for more than 70% of all transport exergy consumption

16. Road transport is more than fivetimes less efficient than rail transport

17. Transport accounts for more than 25% of all UK environmental impacts

18. Emissions from air transport have increased by more than 300% since 1970

19. Road transport accounts for more than 70% of all transport emissions

20. Road transport has 7½times greater impact on the environment than rail

21. 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? Connectivity the economic and social key?

22. 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 Connectivity the economic key?

23. 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 Connectivity the economic key?

24. Biting the Chinese Bullet

26. 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? Connectivity the economic and environmental key?

27. We would reduce the amount of road traffic increase our exports reduce journey times increase the number of tourists reduce the amount of carbon emissions Connectivity the economic and environmental key?

28. What ifwe: 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? Transport, the environmental key?

29. We would: 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? Transport the environmental key?

30. If we always do what we always did, we’ll always get what we always got
