BBC: China is the world’s largest and fastest-growing source of carbon emissions. To reduce its carbon footprint, the country is working hard to develop renewable energy sources and replant its forests, according to Xie Zhenhua, China’s senior climate negotiator. The subject is one of many being discussed this week at the United Nations Framework Convention on Climate Change in Bonn, Germany. Although Xie said China leads the world in installed capacity of wind, solar, and bioenergy, its economic development has been taking precedence over environmental considerations. While China’s scientists have yet to set a date for capping the country’s carbon emissions, Xie said they hope to have a plan in place before next year’s climate change conference in Paris, which will center on establishing a global climate treaty.
