Sustainable Resource Management
Responsible Material Use and Green Procurement
Development and management of buildings involves an extensive use of materials and waste generation. Hence, we set clear guidelines and specifications on the procurement of materials and construction management to reduce the overall impact of our projects across their life-cycle. We also acknowledge that the use of virgin materials can impact the environment and human health. By specifying the use of sustainable and non-toxic building materials in our developments, we can deliver environmental, social, and business benefits.
Beyond adopting good practices in our operations, CDL has had a set of green procurement specifications to promote responsible sourcing along our supply chain since 2008. The guidelines encourage the use of eco-friendly and recycled materials, in alignment with our corporate environmental, health and safety (EHS) Policy. An example is the use of non-toxic materials like low volatile organic compounds paint. All our builders, suppliers and vendors of new development projects are required to comply with these guidelines.

|Cement||73,231 tonnes||Cement||90,648 tonnes|
|Steel||26,254 tonnes||Steel||36,709 tonnes|
|Granite or marble tiles||6,881 tonnes||Timber||5,418 tonnes|
For new projects starting from 2016, we have set a target for 35% of our building materials to be derived from recycled content, low-carbon sources or those certified by recognised environmental organisations.
For the Singapore Sustainability Academy, which started construction in 2016, at least 80% of the structure was built with Cross Laminated Timber (CLT) and Glued Laminated Timber (Glulam). CLT in particular is harvested from sustainably managed forests. Both CLT and Glulam used in the construction of the Academy were verified by the Nature’s BarcodeTM system as coming from responsible sources. The system entails scientific tests like DNA analysis to minimise the risk that the wood materials are derived from illegal logging activities.
