ClairCity is an innovative project involving thousands of people across Europe

The project enabled us all to decide the best local options for a future with clean air and lower carbon emissions. This is our story!


ClairCity is funded by the European Union.

About us

ClairCity was a four year project (2016-2020) that worked directly with citizens and local authorities in six countries around Europe.

We had 16 partner organisations involved in the project, including 6 cities, each of which face different issues and causes of air pollution: Amsterdam (The Netherland), Bristol (UK), the Aveiro Region (Portugal), the Liguria Region (Italy), Ljubljana (Slovenia) and Sosnowiec (Poland). All of our partner cities are working to improve their air quality. Access all our reports here.

The ClairCity process

ClairCity engaged citizens across Europe to better understand their environmental behaviours in their local contexts. The project was curious to know how they travelled, how they heated their homes and their future aspirations. Were citizens interested in adopting greener lifestyles? And if so, how would this affect carbon emissions and air pollution by 2030 and 2050? Importantly, would their involvement in decision making processes accelerate the transition to a clean air, zero carbon futures?

The engagement process consisted of three parts. First, establish a baseline of behaviours in each of partner cities and regions and explore the policy and governance landscape to understand how this impacts on citizens behaviours. Second, engage citizens in various creative ways and use cutting-edge modelling to understand what happens to air quality and carbon emissions when their suggestions are incorporated into decision making. Third, feed back this knowledge to policy makers, citizens and influential organisations in each city and region.

The project produced a series of webinars on the ClairCity method. You can read more about the modelling approach in this blog, or watch our modelling webinar here. To explore our engagement tools and techniques then click below, or watch our webinar on the topic:

Citizen engagement tools and techniques

To learn the lessons for policy, we have a webinar on this topic also. And finally, to hear from local perspectives, we hosted a session with community organisations pushing for policy change and citizen involvement in Bristol.


The Team

ClairCity was made up of academic and professionals from all areas, contributing to the cause using their knowledge and passion. The team hailed from countries around the EU including the UK, Norway. the Netherlands, and Hungary.

All of our activities help us to collect resident's views, understand the unique problems cities faces, and inform the cities we work with on what they can do to improve the lives of residents.
