Note:
  1. In 2021, 2022: the calculation scope of electricity usage covers Weikeng parent company’s operating bases: Taipei Neihu Head Office, Neihu Tanmei Warehouse Center, Taoyuan Housheng Warehouse Center and Central and Southern Liaison Offices (Hsinchu, Taichung and Kaohsiung)
    In 2023, the calculation scope of electricity usage added Weikeng parent company’s Hong Kong Shatin warehouse and, China Shenzhen Futian sublet warehouse.
  2. The calculation scope of gasoline and diesel consumption from 2021 to 2023 is only based on the operating bases of Weikeng’s parent company in Taiwan.
  3. Information source: Electricity usage is based on the sum of the data listed in the monthly electricity bills of each operating base, but the electricity bill for December 2023 has not yet been sent and collected on the publication date, so the electricity usage in December 2022 is used for that month.; gasoline and diesel are mainly based on actual consumption.
  4. Calorific value conversion coefficients of various energy sources: 1 kWh of electricity = 3,600 KJ; 1 L of gasoline = 32,635.2 KJ (7,800 kcal); 1 L of diesel = 35,145.6 KJ (8,400 kcal).
  5. 1 gigajoule (GJ) = 109 joules (J).
  6. The individual sales revenue has been changed to " NT$ Million" to align with the climate-related information disclosure requirements for listing on the Taiwan Stock Exchange. Concurrently, adjustments have been made to the information from 2021 to 2022 accordingly.

Greenhouse Gas Organizational Inventory

Weikeng Scope 1 energy consumption for Year 2023 includes gasoline and diesel, refrigerant replenishment, water and fertilizer (septic tanks), and firefighting activities (CO2 fire extinguishers) with an emission volume of 95.91 tons of CO2e. The main Scope 2 energy consumption for year 2023 was purchased electricity with an emission volume of 373.44 tons of CO2e. Scope 3 (Category 3 + Category 4) emissions are 998.01 metric tons of CO2e.The total emission volume was 1467.36 tons of CO2e (Scope 1 +Scope 2 +Scope 3((Category 3 + Category 4)), and greenhouse gas emission intensity was 0.0443 tons of CO2e/NT$ Million, an increase of 1,095.92 tons of CO2e in total emission volume, and an increase of 295.05% in greenhouse gas emission intensity from 2022. The reason for the increase is due to the expansion of the Company's inventory boundaries to Hong Kong Shatin warehouse and Shenzhen Futian sublet warehouse, and the addition of Scope 1 (Category 1) emission sources and also the addition of Scope 3 (Category 3~4).

Note:
  1. Greenhouse gas inventory adopts the operation control method and no GHG emissions base year has yet been established. Greenhouse gas data has not been externally verified by a third party and is only calculated by the Company's own inventory.
  2. The scope of the greenhouse gas inventory in 2021 and 2022 covers the operating bases of Weikeng’s parent company in Taiwan: Taipei Neihu Head Office, Neihu Tanmei Warehouse Center, Taoyuan Housheng Warehouse Center and Central and Southern Liaison Offices (Hsinchu, Taichung and Kaohsiung); The scope of greenhouse gas inventory in 2023 has been expanded to the Hong Kong and China warehouses of Weikeng's parent company: Hong Kong's Shatin warehouse and Shenzhen Futian sublet warehouse.
  3. In 2021, 2022: The types of greenhouse gases that were inventoried include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
    In 2023: The types of greenhouse gases that were inventoried include Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3)
  4. In 2021, 2022: Scope 1 includes petrol and diesel, which are mainly used in official vehicles and trucks.
    In 2023: Scope 1 includes (1) petrol and diesel, which are mainly used in official vehicles and trucks(2) Refrigerant supplement (3) Water and fertilizer (septic tank)(4) Firefighting activities (CO2 fire extinguisher)
  5. Scope 2 mainly includes purchased electricity.
    • (1)Weikeng’s parent company in Taiwan region: citing the electricity carbon emission coefficient announced by the Energy Administration, Ministry of Economic Affairs, who updated the electricity carbon emission coefficient quoted in 2022 to 0.495 kg CO2e/kWh; the 2023 electricity carbon emission coefficient has not yet been announced, so the 2022 carbon emission coefficient (0.495 kg CO2e/kWh) will continue to be used for the calculation in 2023;
    • (2)Hong Kong: citing the electricity carbon emission coefficient 0.39 kg CO2e/kWh announced by CLP Power Hong Kong per 2022 report;
    • (3)China: citing the electricity carbon emission coefficient 0. 0.5703tCO2/MWh announced by the Ministry of Ecology and Environment of the People’s Republic of China.)
  6. The new Scope 3 (Category 3 + Category 4) been added in inventory activity data in 2023 is as follows:
    Category 3:
    • Upstream transportation and distribution (packaging materials)
    • Downstream transportation and distribution
    • Employee commuting
    • Business travel
    Category 4:
    • Purchased goods (packaging materials)
    • Indirect emissions from purchased energy - purchased electricity
    • Indirect emissions from purchased energy - transportation
  7. Category 5~6 are not included in the inventory because the operational activity data are not significant indirect emission sources.
  8. The GWP values of 6th IPCC report (2021) were cited.
  9. Greenhouse Gas Emissions in the Last Two Years (The conversion coefficients used are sourced from the latest Greenhouse Gas Emission Coefficient Management Table 6.0.4 version published by the Ministry of Environmental, Executive Yuan, International Energy Agency, Table 3.10 from Chapter 3 Book 3 of 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Guidelines to Account for and Report on Greenhouse Gas Emissions and Removals for Buildings in Hong Kong 2010, Hong Kong SME Carbon Audit Toolkit, 2022 CLP Power Hong Kong Report, Ministry of Ecology and Environment of the People’s Republic of China)
  10. The individual sales revenue has been changed to " NT$ Million" to align with the climate-related information disclosure requirements for listing on the Taiwan Stock Exchange. Concurrently, adjustments have been made to the information from 2021 to 2022 accordingly.
