What were the biggest sustainability trends of 2012?

Bridgett Luther, President, Cradle to Cradle Products Innovation Institute:

Proctor and Gamble stepped up with their 100% renewable pledge -- and I think they are really trying to make good on that pledge. The California EPA finally got their cap-and-trade program up and going. Walmart announces the Sustainability Index in China.

 

 

Terry Yosie, President and CEO, World Environment Center:

The beginning of successful efforts to scale sustainability to a global level. Efforts by Unilever and Nestle in engaging farmers and consumers, Coca-Cola in developing a global stakeholder strategy for water management and IBM's Smarter Planet initiatives are hardwiring sustainability into their core business strategies at global scale. There is much to be learned, but these companies are taking sustainability to a new level.

Mark Lee, Executive Director, SustainAbility:

Rio+20, warts and all. Doha's invisibility. Unilever/the ubiquitous Paul Polmon.

 

 

Peter Madden, Chief Executive, Forum for the Future:

The rate of Artic summer ice melt. Lack of action at the big summits: Rio and Doha. Not having climate deniers in the White House.
