New technology and new politics needed to defeat global warming 

“New technologies hold great promise for tackling climate change, but they need to be complemented by new political frameworks”, said Eileen Claussen, President, Pew Center on Global Climate Change. Claussen proposed that "the world needs a much more flexible framework, a framework that will be able to accommodate countries that are very different”. Lars G Josefsson, President and Chief Executive, Vattenfall, responded, "business is ready and has the know-how."  Josefsson cautioned, however, that government policies need to create market incentives as energy efficiency is ultimately an economic decision.
