BILL CLINTON

"I'm pleased that the Dutch Postcode Lottery has launched the Green Challenge to encourage entrepreneurs to develop new ways to fight one of the most pressing issues of our time: climate change. The Green Challenge does just that by providing an incentive for these entrepreneurs to apply their expertise and innovation to move us into a clean-energy future. Additionally, I am grateful for the Postcode Lottery's commitment to fighting climate change and the support it has given my Foundation's work to reduce greenhouse gas emissions around the world."

"The fundamental problem is an entrepreneurial, disorganised, undercapitalised opportunity competing against a highly organised, overcapitalised, old-energy economy that has still many, many people in its grip."
