10. Responsible Action may not equal Sustainability

11. Sustainability - Meeting the needs of people living on Earth while nurturing and restoring the planet’s life support systems - Board on Sustainable Development, 1999

12. What is it that we want to sustain? For whom? For how long?

14. What should be sustained? Environmental scientists: Earth systems Ecologists: Ecological systems Economists: Earth products (ores, minerals) Humanists: Human systems

15. What does the chemical industry want to sustain? The right to operate Feedstocks Suppliers (process equipment, catalysts, etc.) Customers

16. Sustainability Challenge #1 Everything is connected to everything else, so sustainability is a group project

18. Sustainability Challenge #2 In most cases, the limits we are approaching remain uncertain

19. Lake Powell, CO before and after drought

20. Sustainability Challenge #3 Notwithstanding our difficulties in determining limits, there are increasing signs that our society and the planet is approaching limits

21. Limits to Feedstocks: Crude Oil Price, $/bbl

22. Limits to Emissions: Melting Glaciers

31. Computing Resource Stock in Use: Copper in Cities

32. Quantifying stock per capita Step 1: Determine content of major reservoirs Typical auto – 21 kg Cu Typical house – 200 kg Cu

33. Quantifying stock per capita Step 2: Multiply by the number of units in the reservoirs

34. Copper Stock per capita 170 kg Cu35 kg Cu North AmericaBeijing

35. Copper Stock and Copper Need 170 kg Cu North AmericaBeijing Global need 1.7 Pg Cu

36. Limits to Materials: Copper Stock and Copper Supply 170 kg Cu35 kg Cu North AmericaBeijing Global need Global resource 1.7 Pg Cu 1.6 Pg Cu

37. Final Thoughts “Responsible” action is a good thing Sustainability demands a broader perspective, and probably more effort, than responsible action The quantification of sustainability is a work in progress
