Green Products

Delta continues to enhance product energy efficiency and to develop integrated green energy products, energy-saving products and solutions, which help clients conserve more energy and achieve even higher cost-effective performance.



Energy Saving Benefits and the Avoided Emissions of Products

High-efficiency products saved clients 6.58 billion kWh of electricity in 2024

Delta continues to develop innovative energy-saving products and solutions to provide efficient and reliable energy-saving integrated solutions and services. We also continuously improve the energy efficiency of our products to help customers save more energy and achieve better cost-saving performance. Based on the shipment of power supplies, direct-current fans, uninterruptible power supplies, inverters (variable frequency drives), LED street lights, PV inverters, and EV DC chargers shipped between 2010 and 2024, Delta's high efficiency products saved customers an estimated 52 billion kWh of electricity and reduced carbon emissions by nearly 27.09 million metric tons CO2e.

In 2015, Delta was the first in the industry to introduce product energy-saving calculations into ISAE 3000 assurance. In 2023, Delta became the first in Taiwan to calculate avoided emissions and obtain ISAE 3000 assurance in accordance with the "Guidance on Avoided Emissions" published by the World Business Council for Sustainable Development (WBCSD) in 2023.

In 2024, Delta's products saved, in total, 6.58 billion kWh of electricity per year for customers and avoided emissions by approximately 15.23 million metric tons CO2e in the use phase. The twelve products included computer and networking power, ventilating fans, LED street lights, AC-DC adapters, EV DC chargers, LED high bay, UPS, TV power, LED drivers, inverters (variable frequency drive), traction motors, and on-board charging module. For more information, please refer to Appendix 7.5 Summary of Information Assured (IASE 3000, ISAE 3410).

*1 The reduced carbon emissions in 2024 were based on the electricity emission coefficient of 0.494 kg CO2e /kWh for Taiwan in 2023.

  • Product Carbon Footprint

    A number of products have obtained ISO 14067 certificate

    Life cycle assessment (LCA) is a systematic analysis method for environmental impact caused in each phase of input and output from the acquisition of raw materials, manufacturing and assembly, transportation and distribution, and use to final disposal. In order to reduce the impact of products on the environment, Delta has conducted full-scale LCA and Screening LCA on the environmental impact of respective products according to the international standards ISO 14040 and ISO 14044 in each phase, and has introduced green design.

    Since 2010, Delta has selected several representative products to perform product carbon footprint research based on the Life Cycle Assessment methodology in accordance with PAS 2050 and ISO 14067 standards. They included the carbon footprint inventory of notebook external power supply units (adapters), DC fans, PV inverters, high[1]efficiency rectifier modules, switching power supplies, and DC / DC modules for EV powertrains, for which third-party verification statements were obtained. By summarizing the results of several products' LCA, it shows that the environmental impact from the "use phase" of Delta's core products is currently most significant during their life cycle, while "acquisition of raw materials" comes in second.

    In 2022, the Supply Chain ESG Committee worked with all business groups to launch a comprehensive set of product carbon footprint projects. Each business group has established a working group to regularly report on their progress, including the parallel deployment of product carbon footprint calculations, examination of reduction practices for product life cycles, and case studies of green product design.

    Delta has a large variety of products, and for this reason, we calculate our carbon footprint in separate stages. We expanded the product categories included in the inventory to adapters, power chokes, stators, DC fans, LED high bay, wireless APs, electric vehicle charger IC-CPDs, digital projectors, and integrated low-voltage DC brushless vehicle motors in accordance with ISO 14067 Product Carbon Footprint Standards. We also obtained third-party verification statements. We organized in-person training programs and online courses in 2023 to help employees understand product carbon footprints as well as build up their ability to respond to customer requirements. We also compiled lessons learned from the carbon footprint inventory and shared inventory tools and resources through internal announcements to accelerate the internal product carbon footprint inventory.

    Delta released the “Delta Group’s Product Carbon Footprint Strategies” in 2022. We used the existing Delta Material Carbon Emission Database, established a product carbon footprint calculation methodology and introduced international carbon emission factor databases to create a platform of knowledge. We would analyze product carbon footprint hot spots and opportunities for carbon reduction, and use circular business models, green product design, product energy efficiency improvement, partnerships with low-carbon raw material suppliers, voluntary energy conservation and renewable electricity operation in plants, the setup of green logistics, waste management, and continuous engagement, and communication and encouragement for value chain partners to jointly accelerate product carbon footprint reduction actions.

Green Design

Delta has upheld the mission statement "To provide innovative, clean and energy-efficient solutions for a better tomorrow" and has incorporated the spirit of green product design and circular design into the life cycle of products in the development process. We continue to develop and innovate energy-efficient products and solutions to provide efficient and reliable integration solutions and services for energy conservation. Our strategy includes allocating R&D resources to minimize waste. We continue to provide training related to circular design, including principles such as changing from the source, using waste as a resource, maintaining high value utilization and thinking about circular pathways. We also introduce strategies such as circular designs, the selection of low-carbon materials, the provision of product usage rights, the extension of product life cycles, and the creation of residual product value. For example, we use post consumer recycled (PCR) PBT (Polybutylene Terephthalate) on fan blades and fan frames, use recycled copper in metal components, add recycled aluminum and PC recycled materials for products’ outer casings, use eco-friendly product packaging made entirely of paper, use lighting equipment that’s 90% recyclable, and more. The aim is to raise our resource utilization from the perspective of the product life cycle and reduce the environmental impacts when designing products and services, while also satisfying customer expectations.

Hazardous Substance Management

Delta established the Delta Environmental Hazardous Substance Management Policy and Regulations in 2002. Since then, Delta's product design to manufacturing process, including the components, process chemicals, jigs, and packaging materials that make up Delta's products, have all been included in the management system in order to achieve the most comprehensive management. Delta's responsibility and contribution as a global citizen is to insist on producing excellent products that meet green regulations and enhance performance.
