Energy Management

Energy management and energy conservation performance

We established the Delta Energy Online (EnOL) management system to provide real-time energy consumption and load analysis through methods such as energy planning, efficiency, consumption analysis, and equipment management. The EnOL system optimizes equipment operations, enhances power consumption efficiency, and serves as the basis for evaluating energy saving improvements. Delta's energy consumption at global operation sites in 2024 included electricity and fossil fuels (e.g., natural gas, diesel, gasoline, and liquid petroleum) and externally purchased heat. The total energy consumption was 892,407 MWh, with electricity accounting for 92%. The total energy use increased by 10.6% compared to 2023, chiefly due to the expansion of the factory, increase of production lines and output, which has led to increase the use of electricity. Fossil fuels are mainly used to power emergency power generators, lawn mowers, forklifts, company vehicles, as well as boilers in living areas (including dormitories and cafeterias).

Saved 55,277 MWh of electricity and reduced carbon by around 37,577 metric tons in 2024

In 2011, Delta established a cross functional energy management committee, and an Energy-Saving Technology Team was further organized within the committee. Over the years, the team regularly audited the energy consumption result to find more opportunities and it has implemented various energy conservation and improvement measures for public facilities. These audits serve as checkpoints, allowing Delta to evaluate its progress in reducing energy consumption. By coordinating firsthand experience with energy conservation from internal and external consultants, the team is able to implement these practices at global operation sites. We started implementing the internal carbon pricing mechanism in 2021 and encouraged global operation sites to apply for investment as well as implement energy-saving and carbon reduction projects (e.g., replacing the water ring vacuum pumps at the Wujiang Plant, introducing magnetic suspension chillers at the Dongguan Plant, replacing old chillers at the Pingjhen Plant, and introducing the high-efficiency chillers at the Thailand Plants. These projects were expanded across production plants to strengthen energy and resource management and applied to innovative low-carbon developments as well as innovative energy conservation and carbon reduction technologies.

From 2011 to 2024, Delta's global operation sites have continued to implement energy conservation and carbon reduction measures. The Company put 457 energy conservation projects into practice in 2024 and saved approximately 55,277 thousand kWh of electricity, equivalent to approximately 37,577 metric tons CO₂e. Delta implemented a total of 3,693 energy conservation projects from 2011 to 2024 with an estimated 459,106 thousand kWh of electricity saved, equivalent to a reduction of 350,640 metric tons CO₂e.

Water Resource Management

Saved 47 megaliters of water

Delta is keenly aware of the connections between water safety and the welfare of people and industries. The issues have been extended from the environment to human rights and economic development. Among the 17 Sustainable Development Goals of the United Nations, SDG 6 "Clean Water and Sanitation" aims to ensure availability and sustainable management of water and sanitation for all. Delta's Board of Directors passed the Water Resource Policy in 2024 to enhance the resilience of water management amid climate change and increase Delta's capacity for flexible adjustments in face of severe pressure on water resources in the future. Delta will also continue to conduct water risk identification and adaptation management for global operation sites and Tier 1 suppliers, while developing innovative energy-saving and water-saving products and solutions.

Establishing Risk Assessment Mechanisms

Water is an indispensable resource in the global economy. Delta continues to strengthen operation management and risk identification to achieve sustainable cooperation with partners in the value chain and conduct in-depth analyses of the risks of supply chain interruptions caused by droughts derived from climate change. Delta uses the Aqueduct Water Risk Atlas developed by the World Resources Institute (WRI) to identify the risks to Delta's supply chain and global operation sites. We scored each risk based on the risk elements, such as WRI risk, water consumption, procurement amount, and production value, and the comprehensive final results were used as the basis for Delta's internal decision making. We formulated corresponding measures to ensure adequate response capabilities, make adjustments before risks arise, and implement sustainable management of water resources. Delta shall continue to use the assessment methodology for high-risk plants and plan suitable measures for adaptation.

To raise awareness of water consumption reduction, Delta provides training courses on water efficiency management and water conservation to our employees periodically. In 2024, Delta launched the "Water Efficiency Management" training course on Delta's internal online learning Academy system to explain water management trends as well as share water conservation case studies in plants and buildings in order to cultivate employees' water-related knowledge and develop self-assessment and improvement abilities. More than 100 people participated in the course.

Water Consumption Review

Delta conducts comprehensive water use assessments to identify opportunities for water efficiency improvement. These assessments analyze water consumption and identify areas where water-saving measures can be implemented. The sources of water for Delta's global operation sites consist mostly of tap water (96.6%), which is mainly used in cooling towers, restaurants, and daily general sanitation for cleaning bathrooms. In 2024, Delta's total water withdrawal for global operation sites was 4,192.7 ML (including groundwater 17.2 ML and rainwater 125.5 ML). Water consumption was 1,010.8 ML and water discharge was 3,181.9 ML (91.1% domestic sewage and 8.9% process wastewater). Total water recycled was 505.1 ML and recycled water usage rate was 11%. Global operation sites implemented a total of 12 water conservation solutions in 2024, including: recycling and reuse of discharged water, low-concentration washing water for machine wastewater separation and recovery, replacement of cooling water tower packing, and equipment adjustment and improvement, saving a total of 47 ML of water consumption.

Resource Management

Reduced 450 metric tons of waste

Delta established the "Water Conservation and Waste Reduction Management Committee" in 2016. To promote sustainable resource use and proper waste management, the Committee analyzed waste sources and types, identifying key areas that could be integrated into projects to improve waste management performance, and combined internal and external resources to explore the potential for waste reuse. The scope of the Group’s waste management will be expanded by 2050, with a goal of a 100% waste diversion rate for global operation sites. Delta will continue to improve the diversion rate of waste through reduction, reuse, and recycling to reduce environmental impact, pursue sustainable use of resources and prevent the depletion of Earth's resources.

The data on Delta's waste production are entered in the internal ESG data platform at regular intervals and placed under the centralized management of the system. We also retain the weighing records and government report data for reference. The management units track the vehicles of the institutions responsible for disposal and perform audits from time to time.

Statistically, the total weight of waste at global operation sites processed by qualified disposal institutions was approximately 57,969 metric tons in 2024, of which, non-hazardous waste accounted for 53,929 metric tons (93%), and hazardous waste accounted for 4,040 metric tons (7%).

International Certification and Implementation

The UL 2799 Zero Waste to Landfill Validation was introduced starting from 2019, and the number of certified plants has increased every year. As of 2024, overall production plants have obtained UL 2799 certification, including six plants having platinum certification, the highest level. The goal is to achieve a 100% waste diversion rate for overall production plants by 2025.

Value Chain Waste Reduction Results

Delta's waste reduction starts with its own improvements and it collaborates with the value chain to facilitate effective use of waste and reduce the production of waste in operations, including packaging material recycling, reduction of use in processes, and reuse of cartons, pallets, and trailers to attain reuse and reduction. The total amount of waste generated in value chain activities of Delta's global operation sites totaled 232,485 metric tons. The total amount of all waste converted was 231,509 metric tons and the diversion rate*1 was 99.6%. The revenue from waste recycling totaled 27 MUSD.

Delta continued to promote waste reduction and circular economy measures, and a total of 19 projects were implemented in global operations in 2024, including: improvements to fan heat flow to molds, improvements to material carriers, the reuse of pallets, and more. Total waste reduction amounted to 464 metric tons of waste and saved approximately 0.33 MUSD.
