Interview: Why climate change top G20 economic issue, UN expert

Climate change is closely linked to economic progress and G20 leaders need to address this important issue during the Brisbane summit, said Achim Steiner, executive director of the United Nations Environmental Program in a recent interview with Xinhua. "Climate change is relevant to the G20 because many of the decisions regarding infrastructure investment are dependent on economic policy choices. Building energy efficient and climate resilient cities will be a defining feature of their future utility, both to their residents and to the global community" he said.
