Cities

You can search for articles and other publications, organizations, training courses, projects and programs relevant to different countries and cities by clicking on the list below.

You can also search for data and information on general demographics, transport, energy, air quality, and greenhouse gas emissions in our CitiesACT database. This database also allows you to compare air pollution levels in specific cities against established ambient air quality standards or with other cities. The CitiesACT database will be increasingly integrated into the Clean Air Portal.
