Abstract: Studies on management responsibility for the urban environment have usually focused on structures, institutions and agencies. In terms of structure, urban environmental management is described as administrative and legal structures. From institutions point of view, urban environmental management is based on bureaucracy and the executing department. However, regarding agency, urban environmental management is focused on the responsibility of the residents or community referring to the aspects of their humanitarian acts and social union. Sustainable urban environmental management is often discussed in public and academic discourses concerning structural and institutional roles. The role of the community is usually neglected as it is considered as complicated and subjective. Therefore, this study aims to examine the extent to which the sustainable urban environmental management can be realized, based on the role and responsibility of the city residents. Accordingly, this study intends to uncover the roles of residents and community in managing sustainable urban environment based on the survey, consisting of test and questionnaire, conducted on the residents in the Selayang Municipal Council, in Selangor, Malaysia. The sample of the study involves 167 residents of the Selayang Municipal Council areas which were randomly selected as respondents. The result shows that residents are indeed capable of playing their roles as the agents of managing a sustainable urban environment, due to their abilities and knowledge on the importance of improving the environment. It is recommended that the government and the Selayang Municipal Council authority take approaches which are congruent with the cultural values of the ethnic groups.
