Sustainability Be effective, not nice Keith Clarke

2

This is about...... YOU as a professional, i.e. designer of built environment 3

NOT ABOUT YOUR LIFESTYLE 4

You may choose 1. Cycle 2. Eat meat once a week 3. Wash clothes at 30 °c 4. Recycle 5. Invest in green funds 6. Limit flying... ....and...and.... 5

THIS IS ABOUT WHAT YOU WILL DESIGN 6

Sustainability • Basic – WWF ‘One World’ • Triple bottom line • CSR – Corporate Social Responsibility 7

Sustainability • Leftish • Fairness • Simpler lives ? • Vaguely anti-International Corporation • Widely used to improve ‘image’ 8

Sustainability • Fundamentally correct • Has not succeeded as a movement 9

Two game-changers 1. Population 2. Climate change 10

Climate change is real • Stern Report • Inconvenient Truth • IPCC Reports • Royal Society 12

Copenhagen Accord below 2 degrees Celsius a comprehensive adaptation programme including international support.

UNCERTAINTY CONSEQUENCES 24

2° c ± appears inevitable 25

Can we create economic growth not fuelled by fossil fuel ? 26

40 years changed the world 27

10 years introduce CO 2 E significant design constraint 28

10 years introduce CO 2 E significant design constraint 29

Ignore bankers i t’s engineering that matters 30

How do you become effective ? (you can still be nice) 31

Don’t boil the ocean 32

Do comparators 33

Be prepared to be wrong 34

Thank you 35
