For over a decade, CDL has been advocating environmental sustainability in Singapore’s built environment. We make it our business to take concerted efforts towards preventing pollution on the environment and striving to apply environmentally-friendly practices in our operations.

As part of the ISO 14001 framework, CDL identifies significant environmental aspects for our business operations that can potentially have critical negative environmental impacts. The risk level of environmental aspect is determined using a risk assessment technique consisting of the likelihood of the occurrence, severity of the impact and control measures.

Additionally, our Environmental, Health and Safety (EHS) Policy sets the strategic direction for all employees to take practical efforts to ensure effective EHS management so as to create a "Safe and Green" culture, continually striving to conserve resources and prevent pollution.

CDL actively evaluates the key significant environmental aspects at our work sites, investment buildings and corporate office. From our assessment, energy use, water use, waste generation, carbon emissions and safety management are our most significant environmental aspects. We also cover other aspects such as noise, biodiversity, paper use and waste paper recycling.

Significant environmental aspects are identified and measured by respective business divisions and include key data from Projects Division, Property & Facilities Management Division, Corporate Management and Operations.

(1) National Climate Change Secretariat -Singapore vulnerabilities to climate change (March 2008). (2)''Net zero'' or carbon neutralise refers to achieving net zero carbon emissions by balancing a measured amount of carbon released with an equivalent amount offset.

In 2011, we have reduced CDL's total carbon intensity emissions as measured in tonnes CO2/m2 by 7% from baseline year 2007. In other words, we produced less carbon per leased square metre of area. Since 2009, CDL voluntarily reduced our annual carbon emissions to "net zero"(2) for 11 Tampines Concourse, the first CarbonNeutral(r) development in Singapore and Asia Pacific, and our Corporate Office operations including our data centre.
