The parameter standard for exhaust gas: Nitrogen Oxides (Nox): 820, Sulphur Oxides (Sox): 805, Particulate Matter (PM): 246. 2.The sources of exhaust gas emission includes the exhaust gas emission from production and vehicles. The data is calculated based on the actual amount of emission and the Reporting guidance on Environmental KPIs published by HKEX. 3.The data refers to the actual amount of non-hazardous wastes generated. 4.The data refers to the actual amount of hazardous waste generated. 5.To achieve greater consistency between greenhouse gas accounting and operational accounting, and to ensure comprehensive coverage of relevant responsibilities and potential risks, the Group has adopted the operational control approach for greenhouse gas emission accounting. This method determines the accounting boundary based on the enterprise's control over the implementation of operational policies, thereby more accurately reflecting the enterprise's actual responsibility in carbon emission management. This approach supports the Group in strengthening its monitoring and management of greenhouse gas emissions and ensures that the related accounting results align with our sustainable development goals. The greenhouse gas categories covered include carbon dioxide, methane, and nitrous oxide. 6.Sources of Scope 1 – direct greenhouse gas emission includes the fuel combustion for stationary sources and vehicle, and the consumption of refrigerants, while the reduction of greenhouse gas comes from tree planting in the production base. The data is calculated based on the Chinese national standards GB/T32151.10 - 2015 Requirements of the greenhouse gas emissions accounting and reporting – Part 10: Chemical production enterprise and the Reporting guidance on Environmental KPIs published by the HKEX. The conversion factors used in the calculation of emissions from the combustion of fuels in stationary sources, vehicles, and refrigeration and air conditioning equipment are based on the “Guidelines for Greenhouse Gas Emissions Accounting and Reporting for Chemical Production Enterprises” and “Guidelines for Greenhouse Gas Emissions Accounting and Reporting for Land Transportation Enterprises” provided by the National Development and Reform Commission ("NDRC") as well as the Sixth Assessment Report provided by the Intergovernmental Panel on Climate Change (IPCC). 7.Sources of Scope 2 – indirect greenhouse gas emission of energy includes the greenhouse gas emission involved in purchased electricity. The data is calculated based on "2021Carbon Dioxide Emission Factor of Electricity" issued by the Ministry of Ecology and Environment of PRC and National Bureau of Statistics of China on 12th April 2024. The conversion factors used in the calculation are based on the Guidelines for Greenhouse Gas Emissions Accounting and Reporting for Enterprises, Power Generation Facilities (Revised in 2022). 8.Sources of Scope 3 –indirect greenhouse gas emissions generated from Category 1 (Purchased Goods and Services), Category 2 (Capital Goods), Category 4 (Upstream Transportation and Distribution), Category 5 (Waste Generated in Operations), Category 6 (Business Travel), and Category 9 (Downstream Transportation and Distribution). The emission factors used for calculating emissions were derived from the following sources: China Product Life Cycle Greenhouse Gas Emission Factors Database ( lca.cityghg.com) , the ecoinvent database, the U.S. Environmental Protection Agency's Supply Chain Greenhouse Gas Emission Factors, the UK Department for Energy Security and Net Zero's "Greenhouse Gas Reporting: Conversion Factors 2025," and the Carbon Emissions Calculator published by the International Civil Aviation Organization (ICAO). The increase in Scope 3 greenhouse gas emissions for the Year is primarily due to the expansion of reporting categories compared to the previous year, with more emission sources that were previously not included being brought into the calculation scope. Expanding the calculation boundary of Scope 3 helps to more clearly define the attribution of emission responsibilities across the upstream and downstream of the value chain, reflecting our commitment to our own environmental footprint and our transparent accountability. 9.The data refers to actual water consumption record. 10.The saved volume of purchased water is the amount of water saved through water reuse. 11.The data is based on the Group's actual usage records of packaging materials. 117 1 , 841 , 753 1 , 343 , 885 39 .07 4,673,615 4,131,396 4,131,125 99.14 Indicators 2025 2023 2024 The United Laboratories International Holdings Limited 2025 Environmental, Social and Governance Report
