Greenhouse Gas (GHG) Management

Since 2022, STARLUX Airlines has conducted greenhouse gas inventories and continuously enhanced data quality and management mechanisms. According to inventory results, Scope 1 and Scope 2 emission intensity in 2025 decreased by 26% compared with 2022, demonstrating the effectiveness of our carbon reduction efforts. Considering our operational growth and continuous fleet expansion, STARLUX Airlines has adopted the 2024 Scope 1 and Scope 2 emission intensity of 27.61 metric tons of CO₂e per million NTD revenue as the baseline value to ensure the representativeness and comparability of our carbon reduction targets. We have established a short- to medium-term target to reduce emission intensity by 1% annually.

In addition, STARLUX Airlines has committed to adopting the Science Based Targets initiative (SBTi) in 2026 and plans to recalibrate the baseline year in 2028 to align our carbon reduction targets with SBTi requirements, ensuring the implementation of reduction pathways across different emission scopes. We have set a milestone target to reduce Scope 1 and Scope 2 emission intensity by 5% by 2030 compared with 2024, while continuously reviewing and adjusting our reduction pathways based on operational development to align with our goal of achieving net-zero emissions by 2050.

To further implement our carbon reduction strategies, STARLUX Airlines plans to gradually increase the use of Sustainable Aviation Fuel (SAF), targeting an average SAF blending ratio of 2% by 2027 and increasing it to 5% by 2030. Meanwhile, we have established an annual electricity consumption reduction target of 1% compared with the previous year and will continue to improve energy efficiency. Regarding Scope 3 emissions management, STARLUX Airlines will progressively require suppliers to disclose their electricity-related greenhouse gas emissions data, strengthening the foundation of supply chain carbon management and providing a basis for future Scope 3 reduction strategies and target setting.

In 2024, STARLUX Airlines completed its first greenhouse gas inventory for fiscal year 2023 in accordance with ISO 14064-1:2018 and obtained external third-party verification for the first time in May 2024. We further expanded the inventory boundary to include overseas branches and operational sites in Japan, North America, Indonesia, Hong Kong, Thailand, Malaysia, the Philippines, Vietnam, Singapore, and Macau, covering 10 overseas locations, and obtained third-party verification for these inventories. Going forward, STARLUX Airlines will continue to conduct annual greenhouse gas inventories and strengthen our corporate carbon management practices.

STARLUX Airlines’ total greenhouse gas emissions in 2025 amounted to 1,371,612.91 tCO₂e. Category 1: Direct GHG emissions accounted for 98.65% of total emissions, primarily arising from aircraft operations. Category 2: Indirect GHG emissions from imported energy accounted for 0.62%, mainly resulting from electricity consumption at our operational sites. Category 3: Indirect GHG emissions from transportation and Category 4: Indirect GHG emissions from products used by the organization accounted for 0.91% of total emissions. Our carbon emissions increased by 38.35% compared with the previous year, mainly due to continued fleet expansion and increased flight operations. Going forward, STARLUX Airlines will continue to monitor progress toward our short-, medium-, and long-term carbon reduction targets through regular greenhouse gas inventories and contribute to global climate action.

• Inventory Scope Expansion: From 2022 to 2023, the GHG inventory covered the Taiwan headquarters and its main operational sites. In 2024, the scope expanded to include global operational sites, including newly added offices in Taiwan and 10 overseas subsidiaries and their operational locations. 

• GHG Types: The inventory covers seven greenhouse gases: Carbon Dioxide (CO₂), Methane (CH₄), Nitrous Oxide (N₂O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulfur Hexafluoride (SF₆), and Nitrogen Trifluoride (NF₃).

• Inventory Methodology: The operational control approach was used for the GHG inventory.

• Emission Factors: Emission factors are referenced from the Ministry of Environment’s 2024 announcement of GHG emission factors and the Product Carbon Footprint Information Platform.

• Historical Verification: In 2023, in accordance with the CORSIA program, STARLUX completed the 2022 aviation fuel verification. In 2024, following ISO 14064-1:2018, the 2023 GHG inventory was completed. Therefore, 2022 GHG data only covered CORSIA aviation fuel verification and preliminary estimates of non-CORSIA aircraft fuel and purchased electricity at operational sites.

• Scope 3–6 Coverage (2024): Includes upstream emissions from purchased energy in the value chain, employee commuting, business travel, and other sources of GHG emissions.
