This chapter examines the environmental law system of Singapore, with particular emphasis on the role of an effective environmental management system (EMS) in the city-state’s successful management of the environment. The EMS of Singapore consists of an administrative framework, comprehensive land use planning, and the implementation and enforcement of effective pollution control laws. Before analysing the central features of the EMS, the chapter provides an overview of Singapore’s legal system and sources of law. It then considers the structure and substance of environmental law as it applies to pollution control (air pollution, pollution from stationary sources/industries, pollution from vehicles, emissions from other sources), water pollution and water management, waste management, contaminated sites, noise, nature conservation, and climate change. The discussion concludes with an assessment of the administrative framework for environmental management, focusing on the role of government agencies and strategies for land use planning, including judicious siting of industries.
