Through compiling the Sustainability Report, we review the sustainability performance of DSD throughout the year, and elaborate on our efforts and commitment to stakeholders and the general public.
Reporting Scope and Boundary
GRI G4 Guidelines emphasise ‘materiality’ of the aspects, and encourage organisations to report the key information with which the stakeholders are most concerned. Since 2013-14, we have carried out relevant stakeholder engagement exercises when compiling our Sustainability Reports. We will invite stakeholder groups in stages, with reference to their characters, to explore their concerns about DSD’s work. This year, we strengthened the ties with the following two stakeholder groups, and collected and analysed their views through focus group meetings and surveys.
During the process, stakeholders were asked to evaluate the relative importance of various aspects regarding DSD’s sustainability issues and performance. After analysing the results from the stakeholder engagement exercise, the list of Material Aspects identified were submitted to DSD’s senior management and Taskforce on Sustainability Reporting for final review and endorsement. 
The Material Aspects and the corresponding Boundaries covered in the Report are listed as follows: 
|Category||Material Aspect ||Boundaries |
|Operations of DSD||Operations of Our Major Consultants and Contractors|
|Effluents and Waste Treatment||✔||✔|
|Use of Materials||✔|
|Water Resources Management||✔|
|Indirect Economic Impacts||✔|
|Social||Results of Survey Measuring Customer Satisfaction||✔|
|Occupational Safety and Health||✔|
The Report covers the Material Aspects arising from offices and facilities operated by DSD, as well as those from the operations of our major consultants and contractors.  DSD has made every effort to ensure the accuracy of the data and information provided herein, however we rely on relevant parties to provide part of such data and information that we do not have direct control.
