As part of the official launch of the China Council for an Energy-Efficiency Economy (CCEEE) in Beijing, Christopher James spoke on engaging air and energy regulators to help China reach for blue skies. Energy efficiency is a highly-effective, low-cost air quality control resource, that jointly reduces PM 2.5, NOX, mercury, and greenhouse gases. Working together, China’s air and energy regulators can bring about dramatic change by strategically leveraging the benefits of energy efficiency in the various air quality plans being developed by China’s 113 key cities. Industrial energy efficiency, in particular, can play a key role as China strives to meet the ambient concentration requirements outlined in the State Council’s “Ten Measures” announcement by 2017.
