Notes:
₁ Emissions data covers entities that produce GHGs from the combustion of fossil fuels consumed in our Energy business’ assets. It excludes emissions from anaerobic wastewater treatment plants, and maintenance and servicing equipment. Only CO2, CH4 and N2O emissions are included in the calculation of direct GHG emissions. Global warming potential factors used are from the UN 2006 Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report for 2016 data, and the IPCC Fifth Assessment Report for 2017 and 2018 data. A 100-year time horizon is applied. Commentary on our performance may be found on page 2 of the 2018 Environmental Performance Data and Commentary
₂ Emissions data for 2016 is presented using an operational approach, while emissions data for 2017 and 2018 are presented using an equity approach. Data by equity share can be found on page 3 of the 2018 Environmental Performance Data and Commentary
₃ Data for waste generated excludes waste that is collected and incinerated for our customers. Commentary on our performance can be found on page 5 of the 2018 Environmental Performance Data and Commentary
₄ A significant spill is defined as that which resulted in a fine equal to or above S$50,000
₅ Health and safety data reflects group-wide performance. Data covers both assets in operation and under construction. A detailed breakdown of health and safety data is available on pages 3 to 8 of the 2018 Social Performance and Data Commentary
₆ Data covers employees and contractors as well as members of the public. Details of fatalities are reported on page 1 of the 2018 Social Performance Data and Commentary
₇ The accident severity rate excludes fatalities. The accident severity rate including fatalities is reported on pages 4 and 5 of the 2018 Social Performance and Commentary report
₈ Data covers both voluntary and involuntary turnover of permanent employees of Sembcorp and our subsidiaries, excluding Sembcorp Marine
₉ Data covers permanent and contract employees
10 Data from 2017 onwards covers assets under construction

Notes:

Please refer to Reporting Framework and Scope for details on our scope. 

¹ Emissions data covers entities that produce GHG from the combustion of fossil fuels consumed in our Utilities business’ assets. It excludes emissions from anaerobic wastewater treatment plants, and maintenance and servicing equipment. Only CO₂ , CH₄ and N₂O emissions are included in the calculation of direct GHG emissions. Global warming potential factors used are from the IPCC Fourth Assessment Report for 2015 and 2016 data, and the IPCC Fifth Assessment Report for 2017 data. The time horizon applied is a 100-year time horizon. Commentary on our performance may be found on page 2 of the 2017 Environmental Performance Data and Commentary.
² Data presented here is calculated using an operational consolidation approach. Data by equity share can be found on page 2 of the 2017 Environmental Performance Data and Commentary.
³ The GHG emissions intensity figure for 2015 has been estimated. A small proportion of data on energy attributed to steam production in 2015 was not available and was estimated based on data from 2016.
⁴ Data for waste generated excludes waste that is collected and incinerated for our customers. Commentary on our performance may be found on page 4 of the 2017 Environmental Performance Data and Commentary.
⁵ Health and safety data reflects group-wide performance within the reporting scope stated for each respective year. Data covers both assets in operation and under construction. A detailed breakdown of health and safety data is available on pages 5 to 9 of the 2017 Social Performance Data and Commentary.
⁶ Data covers employees and contractors as well as members of the public. Details of fatalities are reported on page 2 of the 2017 Social Performance Data and Commentary.
⁷ The lost time injury rate covers fatalities of employees and contractors only.
⁸ The accident severity rate excludes fatalities. The accident severity rate including fatalities is reported on pages 8 and 9 of the 2017 Social Performance Data and Commentary. 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.
⁹ Data covers both voluntary and involuntary turnover of permanent employees of Sembcorp and its subsidiaries, excluding Sembcorp Marine.
¹⁰ Data covers permanent and contract employees.
¹¹ Data from 2017 covers assets under construction.
^r Indicates restated figure. Details can be found on page 9 of the 2017 Performance Data and Commentary.
^e Indicates data is based on management’s best estimates; we look to further refine the accuracy and consistency of the data.
