Research

Cities are where many of the sources and impacts of the climate and air pollution crises are concentrated – but, in Europe, they’re also where momentum and innovations are growing the most. 


We produce rankings and analysis on the best design and implementation of these policies. In doing so, we strive to shift the narrative away from acceptance of the dominance of the car in our urban spaces, to a vision of the healthier, safer cities of the future.
