Novo Nordic - one of the world's largest producers of diabetes care products - recently made a partnership with the biggest Danish energy supplier DONG Energy. Novo Nordic will buy "green energy” from DONG Energy and in this way contribute to the build-up of Danish wind energy. It has redefined itself as a “cleantech” company - working to help its customers save electricity and, at the same time, develop new CO2 reducing technologies. And the Director of Danfoss recently convened a meeting for world business leaders in Copenhagen in order to establish a “Copenhagen Climate Council.”
