In this transcribed 19 minute TEDTalk by Jason Clay of WWF-US from TEDGlobal 2010, now over seven years ago, the strategy Jason outlines – of addressing the 15 key commodities that cause the most environmental damage by targeting the 300-500 big brands that control 70% of the trade in each commodity – still makes great sense.  Excerpted from transcript:

“So what brings the different entities to the table? It’s risk and demand. For the big companies, it’s reputational risk, but more importantly, they don’t care what the price of commodities is. If they don’t have commodities, they don’t have a business. They care about availability, so the big risk for them is not having product at all.”
