Solar Systems on Construction Site: As an early member of Singapore's Green & Gracious Builder Scheme, CSCEC has long adhered to high standards of energy efficiency, waste reduction, and water conservation. The company integrates renewable solar solutions into construction sites to lower carbon emissions, such as solar-powered CCTV systems and rooftop PV systems for temporary site facilities.

At the Riviera Station and Tunnel Project, the rooftop solar system generates 130 MWh annually, reducing carbon emissions by about 50,000 kg per year.

Battery Energy Storage Systems (BESS): CSCEC has deployed BESS at multiple project sites. These systems significantly reduce onsite noise levels and cut carbon emissions during construction by lowering diesel consumption.
