The perception of air pollution and noise in urban environments: A subjective indicator across European countries.

Although urbanization has been a fundamental feature of economic development, increasingly important concerns about environmental quality have led to a wide-ranging debate about the concept of urban sustainability. In this paper, we examine how living in urban areas affects people's perceptions of two specific aspects of environmental quality, namely, air pollution and noise. Specifically, for every country, we develop an indicator that is based on these perceptions.
