Key Strategies

We are committed to an environmentally sustainable developments in energy reduction, water conservation, waste management, and green advocacy amongst our staff, business partners and customers. Our ABC&I framework guides us in adopting green practices at all levels in the organisation.



Environmental Sustainability Committee

 The Environmental Sustainability Committee (ESC) was formed to support the organisation’s sustainability objectives.



Energy Committee

SMRT’s Energy Committee has played a significant role in sustaining our environment and cultivating ‘green’ values across the entire SMRT network. Made up of a team of energy managers and Licensed Electrical Workers (LEW) since 2014, it has rolled out a series of energy saving initiatives such as upgrading of the propulsion system in our first-generation trains to the more energy efficient Permanent Magnet Synchronous Motor, upgrading of station escalators with energy saving features and introducing the first 1MW Photovoltaic system in Bishan Depot. With the transition to the New Rail Financing Framework since October 2016, the Energy Committee has been working with LTA to innovate and incorporate more energy-saving features into assets and renewal projects.

The committee takes pride in educating staff and raising awareness on the importance of conservation, curtailment and responsible use of energy within the organisation as they would allow every staff to play a part in this collective effort to build a cleaner and a greener sustainable transport system. 

Water Committee
The Water Committee has played an important role in supporting SMRT’s environmental sustainability journey. Since its inception in 2016, the water committee has embraced the 3'Rs' approach to Reduce, Reuse and Recycle. A series of water conservation projects and initiatives such as the upgrading of our Train and Bus wash plants, adopting district cooling at CBD stations, rainwater harvesting at Tuas Depot, and working with PUB to connect NEWater piping were realised.

Through collaborations with PUB and various social enterprises, the Water Committee continues to innovate and incorporate water saving initiatives in our business operation.

Waste Committee

Like the Water Committee, the Waste Committee embraces the 3'Rs' approach to reduce and managing waste. 

SMRT has engaged several key licensed contractors to ensure proper collection, transport, processing, recycling and disposal of waste materials. In 2021, approximately 1610 tonnes of scrapped metal products were sent for recycling.

The committee strongly encourages every staff in SMRT to play an active role in adopting environmentally-friendly practices so that we can support the government and community in our drive to become a Zero Waste Nation.

Green Committee
The Green Committee’s objective is to promote SMRT as a responsible steward of the environment. It amplifies the other committees’ messages and initiatives through internal and external platforms and builds awareness on SMRT’s environmental sustainability efforts through staff engagement as well as community engagement and partnership.
