SUSTAINABILITY PERFORMANCE AGAINST OUR FOCUS AREAS
DATA AND ASSURANCE
PERFORMANCE DATA (CONTINUED)
Footnotes
1.
Employee numbers refers to employees that are assigned to approved Sasol
organisational structure Staff Establishment positions, including permanent and
non-permanent structures (project positions, non-permanent employee positions)
as well as individuals that exist outside of formally approved Sasol organisational
structures. These actual headcount figures are not tracked by Group Organisational
Design (OD).
2. The Recordable Case Rate (RCR) is a measure for reporting work-related injuries.
The RCR is the number of fatalities, lost workdays cases, restricted work injuries
and medical treatment cases for every 200 000 employee hours worked. Exposure
hours are defined as the total number of hours the employees or service providers
have spent in the work environment defined to be Sasol premises where the employee
or service provider is potentially exposed to harm, while engaged in work activities.
3. A fire, explosion or release (FER) incident is registered as ‘major’ when it meets any
of the following criteria: (i) it has a FER severity index score of 40 and greater;
(ii) it results in on-site fatality or multiple hospitalisation cases, or off-site injury; or
(iii) it results in direct financial loss greater than US$1 000 000. A FER incident is
registered as ‘significant’ when it meets any of the following criteria: (i) it has a FER
severity index score of 26 and greater but less than 40; (ii) it results in a lost workday
case (LWDC) or more serious injury; (iii) it results in direct financial loss greater than
US$100 000; or (iv) it causes a release in excess of the relevant threshold quantity
for that chemical as defined by the Centre for Chemical and Process Safety (CCPS).
4. Illnesses are recorded as work-related as a precautionary measure. The various
evaluation authorities may subsequently classify them as not work-related, in which
instance they are removed from the records. In addition, service provider illnesses have
been recorded. Reversible and irreversible occupational diseases are now separated
and additional reporting categories have been included to enable a comprehensive
disease overview required for continuous improvement and a proactive approach in
occupational health management.
5. Investment in employee learning excludes the compulsory 1% skills levy.
6. Black employees refers to African, Coloured and Indian people – for the purposes of
South African employment equity considerations.
7. Production – external sales – The boundaries of this figure only include a product that
is destined for sale to Sasol customers, and does not include a product utilised or sold
between the Sasol Group of companies. A decrease in production was noted for 2022
due to significant coal supply shortages resulting from adverse weather conditions
and operational challenges
8. Greenhouse gas (GHG) emissions have been calculated and reported in accordance
with the GHG Protocol (www.ghgprotocol.org) and the Intergovernmental Panel on
Climate Change (IPCC) 2006 Guidelines. In our GHG measurements, we have included
100% of the emissions for the following joint ventures (JVs): Natref in South Africa
and Gas Sourcing and Operations in Mozambique. Data for those JVs where we do not
have a significant influence or operational control is not included. An external
assurance provider has once again independently verified our direct and indirect
emissions levels. Our GHG emission intensity (tons CO2e per ton of product –
external sales) decreased to 3,69 in 2021 from 3,90 in 2020, due to an increase
in the production – meant for external sale.
9. The increase in direct scope 1 carbon dioxide equivalent emissions from Mozambique
is attributed to the inclusion of methane reporting in 2022. The 2019, 2020 and 2021,
Scope 1 Emissions for Mozambique have been restated to include additional data
in 2022.
10. The sum of greenhouse gas emissions from methane, nitrous oxides and carbon
dioxide (Scope 1 only) are expressed as CO2 equivalence emitted and reported as
direct scope 1 CO2e. Our 2022 Direct Scope 1 CO2 equivalent greenhouse gas emissions
for the Energy Business are significantly lower than 2021 and is attributed to reduced
production rates.
11. The Energy Business scope 2 emissions over the past year has increased in comparison
to 2021 due to the increased purchases of electricity well as the increased grid emission
factor from Eskom.
12. Secunda emissions are presented in a regional view which includes the Secunda
Operations site as well as smaller operations located in Secunda. Scope 2 emissions
for Secunda Operations have been re-baselined due to the Air Separation Unit (ASU)
divestment in 2021.
13. The sum of greenhouse gas emissions from methane, nitrous oxides and carbon
dioxide (Scope 1 and scope 2) are expressed as CO2 equivalence emitted and reported
as total greenhouse gas (CO2 equivalent). Although Sasol Energy Business scope 2
emissions increased in 2022 (see note 12), the total scope 1 and 2 GHG emissions
decreased in 2022 and is attributed to reduced production rates.
14. GHG intensity CO2e/ton of product meant for external sale.
15. The definition of GHG intensity underwent extensive internal review in 2022 and
“total production” was decided on as a replacement of product meant for external
sale. This revised intensity provides insight into the total emissions per ton of
product produced irrespective of the final destination of these products. This provides
a more representative view of site intensity irrespective of the nature of the operation.
The total production values utilised for this calculation is based on operational
management control and is in line with Sasol’s SD data reporting philosophy which
excludes subsidiaries and joint ventures at which Sasol has no management control.
Prior to 2022, Sasol reported GHG intensity based on total GHG (CO2 equivalent)
per ton of product meant for external sale. Using product meant for external sale
provides insight into the amount of emissions per ton of saleable product, which may
not be representative for upstream OMEs such as Sasol Mining and Gas, Sourcing
and Operations (Mozambique), which primarily provide feedstock to other Sasol
operating entities.
16. Due to continuous improvements on the calculation methodology for the determination/
quantification on our Secunda Operations stack emissions, such as ensuring dynamic
variables are utilised when converting to mass flow, the Secunda Operations have
been able to improve the accuracy of emissions monitoring and reporting. Due to this
there has been a restatement of data for PMs, NOx and SO2 under SO for the time
period 2019 onwards.
17. At the Secunda Operations, due to limited stack access, ongoing required
maintenance, repairs and calibration have been limited at the west main stack.
The performance figures for this stack, indicating the emissions, reflect conservative
figures based on a predictive modelling tool which considers previous measurements
and various operating parameters. This predictive modelling tool has been technically
verified and is well aligned with historic online data. Maintenance and repair activities
will be completed once the conditions in the stack are safe. In parallel new factory
calibrated analysers have been obtained and installation and commissioning are
nearing completion.
18. For reporting purposes, we use the applicable definitions of regulatory authorities.
In situations with insufficient guidance from legislation, the definitions of hazardous
waste are reported if it is (i) removed from the premises for disposal and/or treatment,
or (ii) disposed of on-site (eg by landfill). These figures exclude coarse ash from waste
is materials left over from manufacturing or consumption, which may be reused or
recycled. Hazardous and non-hazardous waste gasification and fly ash from boilers.
Non-hazardous waste is waste which requires disposal on a general waste landfill site.
19. Energy use: all energy use data are calculated at the standard measurement unit in
gigajoules (GJ) to ensure standard calculation in the Group.
20. Data from operating entities impacted by divestments during the reporting year are
excluded with effect from the date of divestment, except when target setting is
impacted. As per the GHG Protocol, determination of GHG emissions have been
restated from 2017, our baseline GHG target year, to account for the divested units.
While GHG data has been corrected for divestments from 2017, data for electricity
purchased from non-renewable sources does not officially as yet exclude the
divested units for 2019, 2020 and 2021. For scope 2 emission correlation with
electricity purchased from non renewable sources, data excluding the ASU’s are
12 368 thousand GJ (2021); 11 242 thousand GJ (2020) and 11 411 thousand GJ (2019).
An official restatement and assurance of previous energy data will considered for
future reporting.

21. Reporting of electricity purchased from renewable sources from Eurasia commenced
in 2022. Prior to 2022, all electricity purchased was accounted for as “electricity
purchased” irrespective of the source.
22. Reporting of steam purchased from both renewable and non-renewable sources
commenced in 2022. Prior to 2022, all steam purchased was accounted for in
“Other energy use”.
23. Feedstock to electricity (self-generated) decreased as a result of feedstock (gas)
being diverted from power production to the process.
24. Stationary fuel use accounted for under “mobile fuel use” at Americas prior to 2022.
25. Material use: all material data are calculated at the standard measurement unit of
kilotons (kt) to enable calculation of input material across the group.
26. River water consumption (Americas) decreased to 0 in 2022 due to the divestment
of 50% of the Lake Charles Chemical Complex in 2021.
27. Desalinated water (Americas) was reported in 2021 and 2022 due to the divestment
of 50% of the Lake Charles Chemical Complex in 2021. The desalinated water figure
replaces the previously reported river water for Americas.
28. Managing land use and biodiversity: we do not have operations in areas that have
been declared biodiversity hotspots (areas identified as being critical or endangered
eco‑regions). However, we do have interests in areas of potential sensitivity,
particularly as part of some of our upstream exploration and extraction activities.
In accordance with our environmental management practices, the protection of
biodiversity issues is addressed formally in new projects through environmental
impact assessments (EIAs) and in existing projects through environmental
management plans and/or programmes (EMPs). We are also working to assess the
biodiversity of the habitats in land currently owned, leased or managed throughout
the Group.
29. This value previously did not include the area of subsidence as per the latest LiDAR
survey conducted, and was restated in 2022.
30. Legal compliance: No fines or penalties were incurred above the materiality threshold
for the period. The figure includes significant fines and penalties for non-compliance
with all applicable international, regional, national and local laws and regulations
associated with safety, health and environmental issues. Payments include fines due
to non-compliance with laws, regulations and permits, compensation payments and
regular proactive payments made as a result of non-compliance with regulations where
there is a potential for any enforcement action. The payments do not include levies, or
costs for lawyers and product liabilities. For more information on competition matters,
please refer to the Annual Financial Statements.
