Environmental Impact Assessment
Singapore takes a systematic approach to evaluating the environmental impact of development projects, with study findings on potential impact and mitigation measures carefully considered before a project is allowed to proceed.
Last updated 1 July 2026
Singapore adopts a systematic framework to determine and mitigate the potential impact of any new development on the environment. In general, development projects are required to undergo a thorough evaluation process that addresses the development’s potential impact on traffic, public health, heritage, and the environment.
In addition, development projects close to sensitive nature areas are subject to greater scrutiny and may be required to carry out more detailed environmental studies. The findings of all environmental studies are carefully considered in the planning evaluation process in order to determine the extent of potential impact and the adequacy of proposed mitigation measures, before a project is allowed to proceed.
Environmental considerations are an important part of the planning evaluation process.
Planning approvals are granted to development proposals only when they have met the requirements imposed by regulatory agencies. For example, development proposals are expected to meet existing regulatory standards such as the National Environment Agency’s Environmental Protection & Management Act and Environmental Public Health Act, the Public Utilities Board’s Sewerage and Drainage Act in relation to noise, water, air pollution, and the National Parks Board's Wildlife Act for wildlife-related measures.
Beyond this, proposed development projects near sensitive areas, such as Nature Reserves, Nature Areas, marine and coastal areas, other areas of significant biodiversity or with potential trans-boundary impact, are subject to greater scrutiny.
For such projects, technical agencies (such as the National Parks Board, National Environment Agency, Maritime and Port Authority of Singapore, and Singapore Food Agency) are consulted more extensively to determine if a more thorough environmental study is required. Developers may wish to factor in additional time and resources for such projects.
Environmental study findings are carefully considered by the technical agencies in consultation with community stakeholders, including the extent of potential impact and the adequacy of the proposed mitigation measures. These reports are publicly available online, unless there are specific reasons to maintain confidentiality like security considerations.
Views and feedback from nature and community stakeholders will be sought on the findings. The Ministry of National Development/Urban Redevelopment Authority will assess the development project against its potential impact, before granting planning approval for the project to proceed. The developer is required to ensure mitigation measures and monitoring plans are in place to minimise any environmental impact before the commencement of any works.
