April 29, 2014 Decreased Congestion in Beijing Undermines Air-Pollution Efforts Beijing's recent attempt to reduce air pollution by requiring drivers to take their cars off the road one day a week has had the effect of reducing congestion and raising speeds, which has led to increases in emissions of particulates, according to a team led by Cong Sun of Tsinghua University in China. As a consequence, there has been little or even a negative impact on air quality, which may help explain why Beijing has faced increasingly serious air pollution since imposing the one-day-a-week driving restrictions, the researchers say.

FEATURED PRODUCT Six Simple Rules: How to Manage Complexity without Getting Complicated HBS Press Book Does your organization manage complexity by making things more complicated? If so, you are not alone. According to The Boston Consulting Group's fascinating Complexity Index, business complexity has increased sixfold during the past sixty years. Clearly it's time for leaders to stop trying to manage complexity with their traditional tools and instead better leverage employees' intelligence. This book shows you how and explains the implications for designing and leading organizations. The way to manage complexity, the authors argue, is neither with the hard solutions of another era nor with the soft solutions that often follow in their wake. Based on social sciences (notably economics, game theory, and organizational sociology) and The Boston Consulting Group's work with more than five hundred companies in more than forty countries and in various industries, authors Yves Morieux and Peter Tollman recommend six simple rules to manage complexity without getting complicated. Morieux and Tollman give managers a much-needed tool to reinvigorate people in the face of seemingly endless complexity. Buy Now
