1 Direct (Scope 1) GHG emissions data covers entities that produce GHGs from fossil fuel combustion in our Energy, Water, Waste Management and Urban businesses. The data excludes emissions from our anaerobic wastewater treatment plants and maintenance and servicing equipment

2 Energy indirect (Scope 2) GHG emissions include location-based data for all our Energy, Water, Waste Management and Urban businesses. In Singapore, our operations purchase energy from our own assets; to avoid double counting, the emissions resulting from these have been accounted for under Scope 1 GHG emissions

3 Indirect (Scope 3) GHG emissions include our fuel and energy-related activities (Category 3) and use of sold products (Category 11), which are most relevant and material to our business

4 GHG emissions intensity refers to the Group’s total GHG direct emissions (Scope 1) from its activities, indirect emissions (Scope 2) from its energy consumption and biogenic emissions from bioenergy feedstocks, divided by total energy generated and purchased, as calculated using an equity share approach for all operations in accordance with the GHG Protocol

5 Our gross installed renewable energy capacity includes wind, solar and energy storage. It refers to 100% of the tested gross capacity of the plant at commercial operation date or after major upgrades, and assumes 100% ownership of the facility

6 Water withdrawal includes all water we extract from the sea, surface, ground or third-party sources such as wastewater from customers or treated water from water utilities

7 Net water consumption is defined as water consumed by our own sites and administrative offices

8 Data for waste generated excludes waste that is collected for incineration by our Waste Management business

9 Health and safety data covers both assets in operation and under construction

10 Data covers employees and contractors as well as members of the public

11 Lost time injury rate is defined as the number of fatalities and lost work day cases per million man-hours worked. It includes high consequence work-related injuries, which refer to injuries that result in permanent disability and / or injuries that require long-term follow-up such as physiotherapy treatment and where the individual is not expected to recover fully to pre-injury health status within six months

12 In 2021, we streamlined our reporting to replace accident severity rate with total recordable injury rate. Total recordable injury rate is defined as the number of fatalities, lost work day cases, medical treatment cases, and restricted work cases per million man-hours worked

13 Data covers both permanent and contract employees

14 Data covers both voluntary and involuntary turnover

Notes:
1 Emissions data covers entities that produce GHGs from the combustion of fossil fuels consumed by our Energy business’ assets. It excludes emissions from our anaerobic wastewater treatment plants, chemical waste and maintenance and servicing equipment. Emission factors used are from the IPCC Guidelines for National Greenhouse Gas Inventories for 2006. Only CO2, CH4 and N2O emissions are included in the calculation of direct GHG emissions. Global warming potential factors used are from the IPCC Fifth Assessment Report. A 100-year time horizon is applied. Commentary on our performance may be found on page 2 of the 2019 Environmental Performance Data and Commentary
2 Water withdrawal includes all water we extract from the sea, surface, ground or third party sources such as wastewater from customers or treated water from water utilities. The calculation methodology for water withdrawal and discharge was updated to align to the GRI 303: Water and Effluents 2018 Standard. Commentary on our performance may be found on page 6 of the 2019 Environmental Performance Data and Commentary
3 Net water consumption is defined as water consumed by our own sites and administrative offices. Commentary on our performance may be found on page 7 of the 2019 Environmental Performance Data and Commentary
4 Data for waste generated excludes waste that is collected and incinerated for our customers. Commentary on our performance may be found on page 8 of the 2019 Environmental Performance Data and Commentary
5 A significant spill refers to an accidental release of a hazardous substance which results in severe and / or persistent environmental damage, and is classified as having major or massive impact in our Group HSSE Hazard Identification and Risk Management Standard. Significant spills are reported upon occurrence of the incident
6 Health and safety data covers both assets in operation and under construction. A detailed breakdown of health and safety data is available on pages 11 to 19 of the 2019 Social Performance and Data Commentary
7 Data covers employees and contractors as well as members of the public. Details of fatalities are reported on pages 16 to 19 of the 2019 Social Performance and Data Commentary
8 The lost time injury rate is defined as the number of fatalities and lost work day cases per million man-hours worked. It includes high-consequence work-related injuries, which refer to injuries that result in permanent disability and / or injuries that require long term follow up such as physiotherapy treatment and where the individual is not expected to recover fully to pre-injury health status within six months. Details on lost time injury rates is available on pages 16 to 18 of the 2019 Social Performance and Data Commentary
9 The accident severity rate is defined as the number of lost work days per million man-hours worked. We record lost time due to one fatality as 6,000 lost work days, in line with guidelines by the US National Institute for Occupational Safety and Health. Details on accident severity rates is available on pages 16 to 18 of the 2019 Social Performance and Data Commentary
10 Data covers both voluntary and involuntary turnover of permanent employees
11 Data covers permanent and contract employees
r Indicates restated figure. Adjustments were made to 2017 and 2018 renewable energy generation capacity figures for conversion of capacity in Singapore from MWp to MW. Accident severity rate was revised to include fatalities. Details can be found on page 10 of the 2019 Environmental Performance and Data Commentary
e Indicates data based on management’s best estimates; we have since refined the accuracy and consistency of the data

Our key sustainability data is independently assured by PricewaterhouseCoopers LLP. The assurance report can be found on pages 37 to 40 in the 2019 Performance and Data Commentary

Changes in reported data could occur arising from areas such as changes in material sustainability issues, boundaries or information, including the design, definitions and use of disclosures in the report. Upon such occurrences, current disclosures are presented alongside the appropriate restated comparative or historic data.
