ClairCity is an innovative project involving thousands of people across Europe

The project enables 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 is a four year project (2016-2020) working directly with citizens and local authorities in six countries around Europe.

We have 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), Aveiro (Portugal), Liguria (Italy), Ljubljana (Slovenia) and Sosnowiec (Poland). All of our partner cities are working to improve their air quality. Access all our reports here.

What are we doing?

ClairCity has been examining our collective behaviour and practices to better understand air pollution and carbon emissions.

We’ve been using cutting-edge modelling to understand what happens in cities and to offer a range of citizen-generated future city scenarios for reducing air pollution and carbon emissions.

We’ve also been exploring the policy and governance landscape to better understand how this impacts on citizens now and potentially in the future.

Read more about our plans

Citizen viewpoints about how to solve these problems are critical for democratic and practical reasons – we have to live alongside one another and to find agreement on actions and policies if they are to be effective. That is why our fun resources, from our game to our app and our schools activities, have been developed with this in mind. We have been creative in how we engage citizens with the process, encouraging them to have their say.

Solutions will be different for each city. As such, we are developing policy and advocacy packs that are relevant to each partner cities. Our approach can be replicated by other cities and our findings can positively influence policy development for air quality globally  – so please use our resources and share them far and wide.

The Team

ClairCity is made up of academic and professionals from all areas, contributing to our cause using their knowledge and passion. Our team hail from countries around the EU include 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.
