Singapore’s Coastal Protection Bill: a shift in ESG regulation from disclosure to concrete legal obligations

For many corporate clients, ESG regulation in Singapore has historically been associated primarily with sustainability reporting and climate-related disclosure. For instance, listed issuers are subject to mandatory climate reporting requirements under the SGX Rules.

The recently introduced Coastal Protection and Other Amendments Bill (passed by Parliament on 6 March 2026) signals an important shift in the ESG regulatory landscape in Singapore. The Bill moves climate-related obligations beyond disclosure and into the realm of direct operational compliance obligations.

While this Bill is expected to primarily affect private coastal landowners including shipyards, ports, and businesses in the oil and gas and manufacturing sectors (especially in Tuas, Pioneer, Jurong Island, Senoko), it also reflects a broader ESG regulatory trend that businesses beyond these sectors, particularly those with dedicated ESG, risk or compliance functions, should monitor closely.

Background and purpose

The Bill was introduced by the Ministry of Sustainability and the Environment (MSE), for the purpose of safeguarding Singapore’s coastline against rising sea levels and extreme weather events, by establishing clear responsibilities of landowners for coastal protection and ensuring compliance with coastal protection standards. 

This move was in part informed by the results of Singapore’s Third National Climate Change Study published in 2024, which found that the mean sea level is expected to rise by up to 1.15 metres by 2100.

Key Features of the Coastal Protection and Other Amendments Bill

In recognition of Singapore’s particular vulnerability to the threat of sea level rise, the Bill seeks to do the following:

• Impose obligations on landowners and long-term lessees of prescribed coastal segments to implement coastal protection measures for their land plots.
• Require landowners and long-term lessees to inspect, monitor, maintain and repair their coastal protection measures.
• Centralise regulatory control of coastal protection measures under the Public Utilities Board (PUB), whose approval is required for any works affecting coastal protection measures.
• Provide for PUB’s powers of enforcement to enable it to carry out its coastal protection functions, including emergency powers of entry to protect against coastal flooding.
• Create penalties for actions that affect the coastal protection measures, and for failures to comply with a written notice from PUB. Offences created by the Bill can attract fines of up to S$200,000 and imprisonment of up to two years.

The Government has indicated that affected parties will be given at least 10 years’ advance notice to implement coastal protection measures.

In parallel with the new legislation, PUB is expected to release a Coastal Protection Code of Practice (COP) that landowners and long-term lessees are expected to comply with. This COP will specify a set of common design standards and Operation and Maintenance requirements to guide the design, construction, operation, and maintenance of coastal protection infrastructure.

PUB is also working on a new Flood-Resilient Developments (FRD) guidebook to complement the COP for coastal protection. This guidebook will contain guidelines and case studies that can help landowners decide how to enhance the flood resilience of their land and premises.

Commentary

Given the scale and complexity of the obligations introduced under the Bill, companies with coastal assets would be well advised to assess potential impacts early, and consider how to integrate compliance with operational capabilities.

At a broader level, the Bill reflects a significant evolution in ESG regulation in Singapore. Climate resilience is no longer only a matter for sustainability reporting teams and annual reports, but is a core legal and operational issue that requires long term infrastructure planning and capital allocation.

With this Bill, the Government has clearly demonstrated its willingness to impose climate-related regulatory obligations on companies even where compliance could entail significant infrastructure investment. In this regard, early and constructive engagement with regulators can allow companies to benefit from regulatory guidance and technical advice in developing their internal compliance strategies.
