Low Emission Zones (LEZs) are tools that cities are using more and more in addition to Traffic Demand Management strategies to help address issues like congestion, air quality and road safety. The newly launched “Opportunity of Low Emission Zones” publication stemming from the Taming Traffic” report provides an important framework for cities as they consider implementing Low Emission Zones. 

This webinar aims to inspire cities to develop healthier urban spaces through LEZs and TDM tactics to promote climate and equity. It will discuss good practices around promoting LEZ’s, as well as identify possible problems that municipalities may face and solutions presented in the case of Medellin, Colombia, and Beijing and Jinan, China.

We will also be releasing the Portuguese translation of the report in addition to the versions in English and Chinese.

This event will feature live interpretations in Spanish and Portuguese.
