Environmental Sustainability

Sembcorp Marine is committed to mitigating its business impact on the environment and the community. The Group aims to further enhance its service and product offering with optimal use of resources, and with minimal impact to the environment and the community.

At Sembcorp Marine, we are actively managing the risks and opportunities brought about by climate change, ocean ecosystem degradation and resource availability. We reduce emissions by operating more efficiently and increasing the proportion of renewable energy in our total energy use. With two of our largest yards ISO 14001-certified, our environmental management goes beyond compliance with applicable laws, regulations and standards.

By focusing on three key areas in our environmental programme, namely Climate, Earth and Ocean, we are constantly exploring new ways to improve our practices and minimise the environmental impact of our operations.

Sembcorp Marine, together with our sustainability partner Carbon Care Asia, has jointly developed a methodology to quantify our indirect carbon emission savings. This methodology provides a quantifiable assessment of the carbon dioxide equivalent (CO2e) savings attributable to our low-carbon energy solutions, including LNG-battery hybrid tug boats and battery-powered vessels.


Sembcorp Marine is committed to reducing the impact of its business on the environment. The Group’s Environmental Policy guides the monitoring, management and reduction of operational impact on the environment. It addresses group-wide leadership and accountability, communication, legislative and regulatory documentation, risk and change management as well as performance review of environment-related topics.

The yards adopt individualised environmental management systems adapted to the respective locations and managed by committees consisting of HSE personnel, business excellence champions and management representatives from the Group’s operations. These EMS are compliant with strict national regulations such as the National Environment Agency’s Environment Protection and Management Act and Hazardous Waste (Control of Export, Import and Transit) Act, as well as the Maritime and Port Authority of Singapore’s Prevention of Pollution of the Sea Act. All of its yards undergo regular external and internal audits as part of ISO 14001 Environment Management, ISO 9001 Quality Management or ISO 45001 Occupational Health and Safety Management certifications.

All employees, contractors, customers and shipyard occupiers are expected to comply with the associated policies and practices.

Our Environmental Framework

The key environmental areas of concerns include energy use, materials usage and waste management, water resource management, and air quality management. In these areas, the yards aim to:

  • Manage consumption of direct and indirect sources of energy used in the operations
  • Use raw materials such as steel efficiently and reduce different types of waste
  • Encourage recycling for materials including copper slag, steel scrap and paper
  • Optimise water consumption through the use of reclaimed water and other water-saving devices
  • Reduce emissions of greenhouse gases

The Group’s environmental performance can be found in the Environmental chapter of our latest sustainability report here.

Sembcorp Marine proactively manages its consumption of energy emission of greenhouse gas from operations.

Trained energy managers track and monitor the consumption of electricity and fuels. They also implement policies to increase energy efficiency and reduce wastage in the yards.

The Group actively sources for methods to accelerate adoption of environmentally-friendlier sources of energy and reduce reliance on carbon-based fuels. More information can be found below in the Green Future section of the page.


Sembcorp Marine recognises water as a valuable resource and is committed to managing it responsibly.

Water Efficiency Managers at the yards monitor and audit water withdrawal, consumption, discharge and efficiency programmes. Water consumption is mapped across the yards and reclaimed water is used as much as possible in the yards to reduce the stress on potable water from national resources.


Sembcorp Marine practices a policy of not procuring materials, parts, equipment or products containing harmful substances, including asbestos and ozone-depleting compounds such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halon. The Group avoids the entry of conflict minerals into its supply chain by not procuring tin, tantalum, tungsten, gold and other raw materials originating from conflict-affected or high-risk areas.

Marine and offshore superstructures require substantial amounts of raw materials and semi-manufactured parts to construct and repair. The Group is committed to managing this through a range of platforms and initiatives. Automation and increased precision as a result of new technology have resulted in more accurate and efficient material management in the Group’s facilities. Continuous efforts are made to ensure a culture of waste minimisation.

To encourage a culture of sustainability and responsible use of resources, Sembcorp Marine has rolled out an E4Rs (Eliminate, Reduce, Reuse, Recycle and Recover) programme to manage waste and by-products. Various platforms and initiatives ensure all waste is managed responsibly. The Group requires all disposals to be required to be carried out by nationally-certified waste processing companies.



The Group’s new-generation Tuas Boulevard Yard is designed with environmentally friendly and innovative features, in line with the Group’s commitment to environmental sustainability. To maximise energy efficiency, facilities in this yard are arranged to reduce the need for diesel and are fitted with environmentally-friendly lighting, utilities and power systems. A land-based energy management system enables the optimisation of energy management and conservation.

To integrate renewable energy resources into its energy mix and further reduce greenhouse gas emission, Sembcorp Marine installed an extensive solar harvesting farm at the new yard. Jointly developed with one of Singapore’s leading energy providers, the 4.5 megawatt-peak rooftop solar panels will enable the yard to replace part of its electricity consumption with renewable solar power. A digitalised system equipped with storage functions and energy sensors will further enhance the capacity management of the yard’s electricity network. An estimated reduction of 2,500 tonnes of carbon emission at peak load is expected per year. Read more here.



Besides encouraging recycling and resource conservation among our employees, Sembcorp Marine continues to be actively involved in various green programmes targeted at different stakeholders.

To foster a green mindset among the young generation, Sembcorp Marine organises the annual Green Wave Environmental Care Competition for Schools. Sembcorp Marine has also supported the National Environment Agency-Mediacorp Semakau Run organised in support of several beneficiaries including the Singapore Environment Council and the Nature Society (Singapore).
