Since 2007, the Taiwan Headquarters has adhered to ISO 14064-1 standards to conduct organizational greenhouse gas inventories and has passed third-party verification. It calculates seven categories of greenhouse gases and has progressively expanded the organizational boundaries of the inventory. By 2024, the entire group scope has been fully incorporated, conducting organizational greenhouse gas verification in accordance with the GHG Protocol. In response to SBTi, a carbon reduction target pathway has been established, with the base year reset to 2023.
In accordance with MERRY 's greenhouse gas inventory advancement and the planned timeline for science-based reduction targets, the total greenhouse gas emissions for the entire group for 2022 and 2023 are expected to be finalized by the end of 2024, with the baseline year to be reset.

Greenhouse Gas Inventory (Scope 3; Categories 3~6)
Since 2020, MERRY has conducted Scope 3 (Categories 3 to 6) greenhouse gas inventories in accordance with the ISO 14064-1:2018 standard. Beginning in 2024, inventories and verifications are carried out following the GHG Protocol, covering a total of 15 Scope 3 emission categories. The organizational boundary includes the entire group, and third-party verification has been completed by SGS. MERRY 's total emissions in 2024 amounted to 204,020.5976 tons of CO2e. Aside from newly added inventory items, the primary cause of the increase is sales growth. Among them, emissions from Category 3-1 Purchased Goods and Services represent a relatively high proportion; future efforts will continue in collaboration with the supply chain to reduce carbon emissions.
