Can concern for air quality improvement increase the acceptability of climate change mitigation policies?

Air quality and climate change policies are finding new common grounds today as increasing social complexity requires better integration of separate knowledge domains. This chapter addresses the complex relationship between these two policy domains, their scientific background and the related acceptability issue, which varies substantially among countries and social groups and is influenced by social and cultural factors. The first section of this chapter describes the relationship between air quality and climate change policies. Indeed, global CO2 reduction objectives require complex adaptations of socio-economic behaviours that might not directly appear to be related to pollution reduction or to improvement the exposure of citizens to harmful pollutants. Recent studies, however, have confirmed that air pollution and its impacts are one of the main environmental concerns for citizens, even if relevant differences in public perception between countries still remain.
