67 Environmental, Social and Governance Report 2022 ABOUT THIS REPORT ESG Data Summary 4. The intensity calculations for grid purchased electricity, greenhouse gas emissions, water and waste are based on base building consumption for operating assets under our direct control (except for commercial buildings that report waste data on whole building basis) divided by the total GFA of directly managed properties, which include the areas occupied by tenants. Calculated intensity for grid purchased electricity, greenhouse gas emissions, water and waste has increased in 2022 due to the mix of commercial and logistics assets in the portfolio as compared to 2021’s logistics portfolio. 5. The emission factors used in the calculations are sourced from the national governments of Australia, India, South Korea, Singapore, Malaysia, Indonesia, UK, US, and New Zealand. For properties held in remaining countries, we used emission factors from the Institute of Global Environmental Strategies (China), International Energy Agency (Japan), individual local utility companies (Hong Kong) and Carbon Footprint (EU). All selected emission factors are based on the guidance set out by the GHG Protocol. 6. Certified / rated sustainable buildings and Certified / rated “high” sustainable buildings include completed assets that are directly managed by the Group, including single tenanted assets and master leases as at 31 December 2022. This excludes assets disposed during the reporting period. 7. The total rooftop solar power is generated from approximately 85 MW of installed capacity that were completed and fully operational as at 31 December 2022. Australia and India are working towards implementing a system to measure, track and collect solar power generation data from the various rooftop solar systems of varying capabilities, which are controlled by different parties. 8. In China, the landlord has operational control over common areas within certain assets (e.g., logistics parks) even if they are fully leased out to the tenants, i.e., single tenanted or master leases. Thus, the common areas data for both electricity and water are included for these assets. 9. In India, the development assets (i.e., logistics parks) with completed plots or blocks that are operational are included in the data summary. Thus, the landlord consumption data of these completed plots or blocks within these assets are included for reporting. The reported GFA for the sustainable building certifications and ratings, as well as GFA for the directly managed properties reporting the data, cover the entire logistics parks, including plots or blocks which are not yet completed. 10. In South Korea, the landlord has operational control over common areas although the utility bills for electricity and water use are borne by the tenants. For Osan, the grid purchased electricity of the common areas is an estimation by applying a percentage factor on the total GFA of the asset due to the unavailability of the split in GFA between common areas and tenancy spaces. This percentage factor may change year-on-year depending on various factors, such as occupancy. 11. Under ESR Singapore, the portfolio represents the combined ESR-LOGOS REIT’s portfolio of assets following the merger of ESR REIT (ESR Singapore) and ARA-LOGOS Logistics Trust in 1H 2022. 12. The 2021 figures exclude ARA and LOGOS entities, which were only officially acquired in January 2022. In terms of the reporting scope for 2022, the ARA and LOGOS entities include the environmental data for the full calendar year. There is no re-statement of the 2021 figures and no change to the methodologies in the data collection and disclosure in 2022, as compared to 2021. 13. For year-on-year comparison with 2021, directly managed properties which the Group has operational control and have two years of like-for-like data were identified. Based on our analysis, the total number of properties across the Group with two years of like-for-like data for grid purchased electricity and water is 287 and 250 respectively. There was a 2% decrease in grid purchased electricity consumption but a 2% increase in water use, with no material fluctuations noted across the markets. The total number of properties across the Group (excluding LOGOS) with two years of like-for-like data for waste is 177. There was a 2% decrease in waste generation, being not material variance. 14 There is unavailable waste data for LOGOS to perform the like-for-like comparison as the data is incomplete and not tracked.
