In the growing field of urban political ecology, so far not much attention has been paid to air-quality and related policies. In this paper I examine the recent far-reaching air-pollution policies in India's capital, as well as the role of environmental nongovernmental organizations and judicial activism, in view of their implications for different groups of the urban population. I analyze these policies in the wider context of Delhi's ongoing strive for 'city beautification' and for changing (environmental) governmentalities, and reveal a marked middle-class bias in the environmental and judicial activisms practised, which also contributes to the refining of the boundary between public and private environments. Furthermore, it is argued that air quality with its complex sociospatial patterns plays a significant part in the coproduction of urban 'socioenvironments' that needs to be addressed in political-ecological studies.
