How do Higher Congestion Charges at Traffic Peaks Reduce Pollution?

Variable Congestion Charges May Yield More Stable Air Quality and Improved Health(Science News, Dec. 14, 2012)

Also discussed here: Variable congestion charges may yield more stable air quality and improved health(University of Gothenburg,  Dec. 14, 2012)

And here: Synergies and Trade-offs between Climate and Local Air Pollution: Policies in Sweden(Jorge Bonilla, Jessica Coria, Thomas Sterner, Working Paper in Economics #529,  Goteborg University, Apr. 30, 2012)

Today we review a report from Goteborg, the second Swedish city to implement congestion charging,  that examines the impact of these charges on pollution levels by  time of day and time of year. It found that pollution was worse in the morning and in the spring.  This provides a good basis for having charges that change according to the resulting level of pollution, not necessarily to traffic volume which is usually the linkage made for dynamic charging.
