AYER Holdings GHG Accounting and Carbon Stock Assessment
SuSciCo supported AYER Holdings Berhad in quantifying greenhouse gas emissions across its property development and plantation operations.
The engagement included an organisational GHG inventory covering operational emissions, complex Scope 1 sources and selected Scope 3 categories. A separate assessment quantified carbon stocks within oil palm and durian plantations and secondary forest located on reserved land.
Areas of Support
Emissions from Operational Processes
The Scope 1 assessment included emission sources requiring more detailed quantification than standard electricity and fuel calculations.
These included:
- Refrigerant gas leakage from cooling and air-conditioning systems
- Fuel combustion from company-controlled operations
- Emissions associated with plantation and land-management processes
SuSciCo applied appropriate emission factors, documented assumptions and maintained clear calculation records for each material source.
Selected Scope 3 Emissions
SuSciCo quantified:
- Category 1: Purchased goods and services
- Category 5: Waste generated in operations
- Category 6: Business travel
- Category 7: Employee commuting
The categories were assessed using available operational, purchasing, waste, travel and employee-related data and reported separately from direct operational emissions.
Carbon Stock Assessment
SuSciCo separately quantified estimated carbon stocks associated with:
- Oil palm plantations
- Durian plantations
- Secondary forest within reserved land
The assessment provided the Group with structured information on carbon stored within plantation biomass and retained forest areas.
Carbon stocks represent carbon stored at a point in time. They were not deducted from the organisational GHG inventory, presented as avoided emissions or treated as carbon offsets.
Project Value
The engagement provided AYER Holdings with a more structured and documented basis for:
- Reporting organisational greenhouse gas emissions
- Understanding emissions from complex operational processes
- Quantifying selected value-chain emissions
- Assessing carbon stored within plantation and forest biomass
- Supporting future sustainability and climate-related disclosures
The project demonstrates SuSciCo’s capability to manage GHG accounting for diversified operations where refrigerants, plantation processes, land management and biological carbon stocks require distinct technical treatment.
Need Support with Complex GHG Accounting?
SuSciCo supports Malaysian companies with organisational GHG inventories, complex Scope 1 calculations, selected Scope 3 quantification and carbon stock assessments for plantation and forest areas.
What Scope 3 emissions did SuSciCo quantify for AYER Holdings?
SuSciCo quantified Scope 3 Categories 1, 5, 6 and 7, covering purchased goods and services, waste generated in operations, business travel and employee commuting.
What Scope 1 emissions did SuSciCo quantify for AYER Holdings?
SuSciCo quantified direct emissions from company-controlled operations, including fuel combustion, refrigerant gas leakage, and emissions associated with plantation and land-management activities.
These sources required distinct calculation approaches, emission factors and supporting assumptions to reflect the Group’s mixed property development and plantation operations.
