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 Efficiency of Products

High-efficiency products saved clients over 30 billion kWh of electricity every year

Based on the shipment of power supplies, direct-current fans, uninterruptible power supplies, variable-frequency drives, LED lamps, electrical ballasts, PV inverters, and direct-current EV chargers from mainland China, Taiwan, and Thailand between 2010 and 2022, Delta's high efficiency products saved customers an estimated 39.9 billion kWh of electricity and reduced carbon emissions by 21.05 million tons CO2e.

In addition, Delta pioneered the introduction of product power saving calculations into third-party certification in 2015. In 2022, Delta's products saved, in total, 4.02 billion kWh of electricity and reduced carbon emissions by approximately 2.046 million tons CO2. In 2015, Delta was the first in the industry to introduce product energy-saving calculations into ISAE 3000 assurance. Since then, Delta has added product items each year and accomplished assurance of ISAE 3000 product energy conservation for 11 products by 2022. Please refer to Chapter 5.6.4 and Appendix 7.4 Summary of Information Assured (ISAE3000) of the 2022 ESG Report for product power saving calculations.

In 2022, the energy savings of 11 types of products have been assured by ISAE 3000

Product Carbon Footprint

A number of products have obtained ISO 14067 certificate

Product Life-cycle Assessment (LCA) is a method of systematically analyzing the various product life-cycle stages that may have an environmental impact, such as raw material acquisition, manufacturing and assembly, sales and transportation, use, and final disposal. To reduce the impact of its products on the environment, Delta has implemented a full-scale LCA and a screening LCA for products in accordance with the international ISO 14040/44 standard, while introducing green design at each stage.

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. This included the carbon footprint inventory of notebook external power supply units (adapters), DC fans, PV inverters, high-efficiency rectifier modules, switching power supply, and DC/DC modules for EV powertrain, for which third-party certificates were obtained. By summarizing the results of several products' LCA, it shows that the environmental impacts from the "use phase" of Delta's core products is currently most significant during their actual life cycle, while "acquisition of raw materials" comes in second.

Delta has a large variety of products, and for this reason, we calculate our product carbon footprint in separate phases. In 2022, the Supply Chain ESG Committee assembled a business group for the comprehensive product carbon footprint system project and published the Delta Group’s Product Carbon Footprint Strategies.

We expanded the types of products including an adapter, power choke, stator, DC fan, LED high bay lights, wireless AP, electric vehicle charger IC-CPD, digital projector, and integrated low-voltage DC brushless vehicle motor for the carbon footprint calculation and verified in accordance with ISO 14067. We adopt the existing Delta Material Carbon Emission Database and established a product carbon footprint calculation mechanism as well as international carbon emission factor databases to create a platform of knowledge. We analyze product carbon footprint hot spots and opportunities for carbon reduction, and will use circular business models, product green design, partnerships with low-carbon raw material suppliers, energy conservation and renewable power operation in plants, 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 prioritizes green design and circular design throughout the product life cycle from the design of source products to the final disposal. We continue to develop and innovate energy-efficient products and solutions to provide efficient and reliable integration solutions and services for energy conservation. 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 smart materials, providing product access, extending product life, and creating product residual value to design products or services from a product life cycle perspective and reduce resource consumption and environmental impacts.

Green Design Strategies

  • Reduce the impact on the environment at each stage of the product life cycle (such as: raw material stage: local procurement of materials; manufacturing stage: in-plant energy conservation projects and use of renewable electricity; transportation and distribution stage: adoption of green packaging design; usage stage: enhancing the energy efficiency of products; final disposal stage: use of recyclable packaging and raw materials)
  • All products comply with international safety standards or international environmental protection regulations (such as: EU RoHS, WEEE, REACH, and China's electronic information product pollution control management measures, etc.)
  • Assist customers with green marketing needs, and product labels comply with relevant information on environmental labels (such as: Taiwan Green Mark, Taiwan Energy Label, US Energy Star ENERGY STAR, 80 PLUS Certification, etc.)
  • Continuously improve product energy efficiency and receive ISAE 3000 assurance to provide clients with product energy saving solutions.

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.
