Speaking to CCTV English, Carnegie-Tsinghua’s Wang Tao discussed the importance of electric vehicles and renewable energy sources in curbing the problem of air pollution as well as the longer term problem of climate change. Wang emphasized that any policy seeking to boost use of electric vehicles must take note of travel demands. While electric vehicles can play a major role in curbing emissions, increasing the number of electric vehicles on the roads too quickly would lead to traffic congestion and higher emissions levels overall, he warned. Wang added that authorities must create more incentives to offset the high cost of purchasing an electric vehicle and build the infrastructure necessary to their use. He concluded by saying that more efforts to develop renewable energy sources were required in order to combat both air pollution and the long-term problem of climate change.
