Greenhouse Gas Inventory (GHG Scope 1 and Scope 2)
In 2025, LITEON’s greenhouse gas emissions were verified in accordance with ISO 14064-1:2018. Direct greenhouse gas emissions (Scope 1) and energy indirect greenhouse gas emissions (Scope 2) from LITEON’s major operating sites amounted to 106,742.2111 metric tons CO2e on a market-based basis. This represented a decrease of 2,290.5835 metric tons CO2e, or 2.10%, compared with 2024, and a reduction of 41,845.3742 metric tons CO2e, or 28.16%, compared with the 2023 Science Based Targets baseline year.
In 2025, greenhouse gas emissions intensity was 0.68 metric tons CO2e per NTD million of revenue, representing a decrease of approximately 21.8% compared with 2024 and 66.7% compared with the 2014 baseline year. LITEON exceeded its original target of reducing carbon intensity by 39.3% by 2025 compared with the 2014 baseline year, as well as the 2025 target under the 555 Carbon Reduction Plan.
Under LITEON’s Science Based Targets 1.5°C short-term pathway, the 2025 target was an 11.76% reduction in absolute Scope 1 and Scope 2 emissions compared with the 2023 baseline year. This target was achieved. LITEON is committed to reducing absolute Scope 1 and Scope 2 greenhouse gas emissions by 58.8% by 2033 from the 2023 baseline year and achieving net-zero emissions by 2050.

Greenhouse Gas Value Chain Inventory (GHG Scope 3)
To maximize value creation across LITEON’s value chain and identify key climate mitigation opportunities, LITEON extends carbon management beyond its own operations to value chain partners. The Scope 3 greenhouse gas inventory is conducted in accordance with ISO 14064-1:2018 and the GHG Protocol and is subject to third-party verification and disclosure.
For the 2025 Scope 3 inventory, LITEON conducted a materiality assessment based on emission volume, reduction potential, and quantification methodology. The disclosed categories cover purchased goods and services, fuel- and energy-related activities, upstream and downstream transportation, waste generated in operations, business travel, employee commuting, use of sold products, and downstream leased assets.
LITEON has established a Science Based Targets short-term reduction target for Scope 3 emissions, using the use-phase emissions of power products in 2023 as the baseline. The Company aims to reduce the average use-phase carbon intensity of power products by 63.8% by 2034. In 2025, product-use carbon emissions intensity reached 0.0834 metric tons CO2e per unit, representing a 15% reduction compared with the 2023 baseline year.
