Sasol Climate Change Report 2022 - Book - Page 62
INTRODUCTION
RISKS AND OPPORTUNITIES
APPENDIX
1
Purchased goods and
services
Upstream emissions from the
production of products
purchased or acquired.
2
Fuel-and-energy-related
activities
Emissions from the production
of fuels and energy purchased
and consumed that are not
included in scope 1 or 2.
4
Upstream transportation
and distribution
Emissions from transportation
and distribution activities
through the value chain,
where Sasol appoints
transporters.
5
DATA AND ASSURANCE
GOVERNANCE
Sasol’s scope 3 emission categories
Activity data
Volume of purchased goods and services obtained from internal business data management systems.
Emission factors
Cradle-to-gate emission factors obtained from data sources, such as GaBi, DEFRA and Sasol’s Lifecycle Inventory Database, based mainly on primary data.
Methodology and assumptions1
Cradle-to-gate emissions, including transport and indirect emissions were used together with appropriate emission factors. A weighted product carbon
footprint was calculated where country specific emission factors were available.
Value-chain engagement
Continued supplier engagement programme to improve accuracy of emission factors.
Changes to data 2022
Emissions reduced overall, primarily due to the use of more accurate emission factors for crude oil sourcing.
Capital goods
Upstream emissions from the
production of capital goods
purchased or acquired.

OUR FUTURE SASOL STRATEGY
Waste generated
in operations
Emissions from third-party
disposal and treatment of
waste generated for owned
or controlled operations.
Although this category is not yet actively reported, we worked to identify a relevant reporting mechanism for inclusion of these emissions in the future.
All segments of Sasol’s global procurement related to the sourcing of capital equipment, such as turnkey projects, machinery and fabricated equipment would be analysed based on the monetary
purchasing volume in the reporting year.
Activity data
Quantities of fuel and energy purchased, obtained from internal business data management systems.
Emission factors
Cradle-to-gate emission factors were obtained from the GaBi database and conversion factors from DEFRA. Transmission and distribution loss factors were
sourced from literature sources, if not already embedded in sourced data.
Methodology and assumptions
Cradle-to-gate emission factors were used together with emissions from extraction, production and transportation of fossil fuels for power and steam
generation.
Value-chain engagement
Continued supplier engagement programme to improve accuracy of emission factors.
Changes to data 2022
Overall increase in emissions from 2021 due to higher steam demand for Sasol Energy and higher gas purchases at our European operations.
Activity data
Quantities and types of goods procured, obtained from internal business data management systems.
Emission factors
Derived from various sources, depending on transportation mode, including DEFRA, GaBi and the European Chemical Industry Council’s studies, to name a few.
Methodology and assumptions
Analysis focused on road, rail, pipeline and marine shipping. GHG emissions were used together with the appropriate emission factors and quantities of
products used per mode of transport.
Value-chain engagement
Focused on road operators in South Africa and marine operators in Europe and North America.
Changes to data 2022
Decrease in emissions due to more accurate activity data sourcing as a result of continuous improvements.
Activity data
Quantities of hazardous and non-hazardous waste generated by Sasol obtained from internal business data management systems.
Emission factors
Default emission factors were obtained from the GaBi database and DEFRA.
Methodology and assumptions
Hazardous and non-hazardous waste emissions were used together with the applicable average emission factor.
Value-chain engagement
Continued supplier engagement programme on waste registers.
Changes to data 2022
Increase in emissions from higher volumes of non-hazardous waste.
1. GWP values refer to the time horizon of 100 years, sourced from IPCC, AR5, 2013.
Most material categories are those with emissions of more than 1 Mt CO2e
