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 over 3 billion kWh of electricity every year

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, directcurrent fans, uninterruptible power supplies, inverters (variable frequency drives), LED street lights, PV inverters, and EV DC chargers shipped between 2010 and 2023, Delta's high efficiency products saved customers an estimated 45.5 billion kWh of electricity and reduced carbon emissions by nearly 23.84 million metric tons CO2e *1.

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 Ten Types of Products Assured by ISAE 3000 in 2023 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 2023, Delta's products saved, in total, 5.65 billion kWh of electricity per year and avoided emissions by approximately 13.78 million metric tons CO2e in use phase. The ten 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, and inverters (variable frequency drive). The revenue from sales accounted for 24.6% of Delta's total revenue. For more information, please refer to Appendix 7.5 Summary of Information Assured (ISAE 3000).

*1 The reduced carbon emissions in 2023 was based on the electricity emission coefficient of 0.495 kg CO2e/kWh for Taiwan in 2022

  • Product Carbon Footprint

    A number of products have obtained ISO 14067 verification

    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 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 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-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. Delta has a large variety of products, and for this reason, we calculate our carbon footprint in separate stages.

    In 2022, the Supply Chain ESG Committee assembled business group for the comprehensive product carbon footprint system project and published the "Delta Group’s Product Carbon Footprint Strategies". 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. 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. We used the existing Delta Material Carbon Emission Database and would establish a product carbon footprint calculation methodology and introduce 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, 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, 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 programs for circular design, including the principles of making changes at the source, using waste as resources, maintaining high-value use, and considering pathways for the circular economy. We introduce strategies for circular design, choosing low-carbon materials, providing product access, extending product life, and creating product residual value to design products or services from a product life cycle perspective and increase the efficiency of resource consumption and reduce environmental impacts.

Hazardous Substance Management

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