Apple CEO Tim Cook is joining the CEO Council for Sustainable Urbanization, a group formed by the Paulson Institute and the China Center for International Economic Exchanges in order to divert the environmental impact of China's urban growth. "Apple is committed to running our global operations on 100 percent renewable energy and we're working hard to reduce emissions throughout our global supply chain," Cook said in prepared statement from the Paulson Institute. "We look forward to participating in the CEO Council's effort to advance China's green transformation and hope to do our part in helping China reach its climate goals."
