Clean Air Zones, Low and Zero Emission Zones are the subject of headlines and political debate in the UK, but our work with colleagues in Poland show that Clean Transportation Zones, as they are called there, are no less controversial. Our research suggests that part of that controversy is due not to the potential impacts and benefits of these policy interventions, but how they are defined, measured and implemented. In particular, we advocate for a more experimental and participatory approach that doesn’t expect immediate and exacting results and allows for more gradual and transformative change.
