GHG Management and Decarbonization

巴黎協議.jpgGreenhouse Gas Management

In accordance with the Financial Supervisory Commission's (FSC) “Sustainable Development Action Plans for TWSE- and TPEx-Listed Companies,” enterprises are required to disclose the results of their greenhouse gas (GHG) inventories and reduction efforts, covering the entities within their consolidated financial statements.

Compal recognizes climate change as a significant challenge to business operations and a core concern for international supply chains. In 2025, Compal completed a comprehensive GHG inventory for all subsidiaries within its consolidated reporting scope, in compliance with ISO 14064-1: 2018. The results were verified by an independent third party, underscoring Compal's commitment to information transparency and sustainability responsibility.

 

Science Based Targets (SBT)
To support the Paris Agreement goal of limiting global warming to 1.5°C, the Company has established short-, medium-, and long-term decarbonization pathways aligned with its Science Based Targets (SBT). Progress is regularly monitored against these pathways, and the results are used to inform decarbonization measures, resource allocation, and the implementation of the Company's climate transition plan.For Scope 1 and Scope 2, 2019 serves as the base year. The Company annually monitors actual emissions against the established decarbonization pathway and annual reduction targets. For Scope 3, 2021 serves as the base year, with ongoing efforts to enhance value chain emissions data collection, calculation methodologies, and supply chain collaboration.

 
Greenhouse Gas Emissions 
To provide a comprehensive overview of the Company's greenhouse gas emissions management, this section discloses GHG emissions for both the standalone financial statements boundary and the consolidated financial statement boundary. All disclosed data have been verified by an independent third party. The standalone financial statements boundary primarily reflects emissions from the Company's parent company operating sites, while the consolidated financial statement boundary covers operating sites within the consolidated financial statement boundary over which the Company has operational control. The latter serves as the primary basis for tracking the Company's overall decarbonization pathway and conducting management reviews.

 

The 2025 GHG emissions results indicate that Scope 1 and Scope 2 emissions for both the Standalone Financial Statement Boundary and the Consolidated Financial Statement Boundary remain consistent with the phased decarbonization pathway established using 2019 as the base year. Overall emissions performance remains aligned with the Company's Science Based Targets (SBT) pathway and continues to progress toward its 2030 medium-term emissions reduction target. Based on market-based emissions, Scope 1 and Scope 2 emissions within the Consolidated Financial Statement Boundary decreased by 9.8% compared with the previous year, while emissions within the Standalone Financial Statement Boundary decreased by 33.5% year over year. These reductions were primarily driven by improvements in energy efficiency, the implementation of energy conservation projects, expanded use of renewable energy, and optimized renewable electricity allocation, all of which contributed to reducing GHG emissions from operating activities. The Company will continue to monitor emissions trends and incorporate energy consumption, renewable electricity allocation, production capacity changes, and the implementation of decarbonization projects into its annual management review to ensure continued progress toward its medium- and long-term emissions reduction targets. 

 

Investment in Energy-Saving Equipment

In 2025, the Company continued to advance energy-saving investments across its sites, combining improvements in management mechanisms with upgrades to key equipment to progressively enhance overall energy efficiency. 

In Vietnam, multiple energy-saving measures were completed in 2025, with a primary focus on strengthening energy management mechanisms, optimizing lighting systems, and introducing variable-frequency energy-efficient air-conditioning equipment. Total energy-saving investment expenditure for the year amounted to approximately NTD 14,158 thousand. These measures were completed and put into operation in 2025, forming an important foundation for overseas manufacturing sites to continuously reduce operational energy consumption and strengthen energy management capabilities.

Taipei Headquarters Chiller Replacement Project: To enhance the operational reliability and energy efficiency of the air-conditioning system, Compal plans to replace two 350 RT chillers at its Taipei headquarters, together with the associated turnkey works. Project planning, benefit assessment, and budget allocation were completed in 2025, with equipment replacement and construction scheduled for 2026. The total investment in equipment and related works is approximately NT$9.52 million. Upon completion, the project is expected to save approximately 280,000 kWh of electricity annually and reduce GHG emissions by approximately 118 tCO₂e per year. In addition to delivering energy-saving and carbon-reduction benefits, the project is expected to reduce the risk of unplanned downtime caused by aging equipment and improve the operational reliability of the air-conditioning system.

Overall, the Company is building on the energy-saving investment achievements completed in 2025 and  aligned with the planned replacement of key infrastructure replacement in 2026. Through a phased, site-specific energy investment strategy, the Company continues to advance energy management refinement, supporting its medium- to long-term carbon reduction and operational efficiency improvement objectives.
