The idea of the label is that showing the financial impact of environmental solutions will help sell the concept of clean and renewable energy to governments and potential financial backers. It's led by Dr Bertrand Piccard, the first person to fly around the world in a solar-powered aircraft. > 'When we consider climate change and consumption, it's not only our comfort, our growth, our lifestyle that is the reason for that,' said Dr Piccard. 'It's the fact that the technologies that we use are wasting half of the energy that is produced. Half of the pollution is only due to the losses, to the waste and the inefficiencies of the systems that are in use today.'
