  • 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 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 2021, Delta's high efficiency products saved customers an estimated 35.9 billion kWh of electricity and reduced carbon emissions by 19.01 million tons CO2e.

In addition, Delta pioneered the introduction of product power saving calculations into third-party certification in 2015. In 2021, Delta's products saved, in total, 2.41 billion kWh of electricity and reduced carbon emissions by approximately 1.21 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 2021. Please refer to Chapter 5.7.4 of the 2021 ESG Report for product power saving calculations.

In 2021, the energy savings of 11 types of products have been assured by ISAE 3000

  • Product Life-Cycle Assessment

    Product energy efficiency is approved by ISAE 3000​​


    Through product technology innovation, Delta promises to continuously improve product energy efficiency, actively develop renewable energy solutions, and introduce green designs at all stages of the product life cycle. This will reduce Delta's environmental impact and achieve responsible product manufacturing and consumption.

    Life-Cycle Assessment

    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.

    Strategies

    • All products comply with international safety standards or international environmental regulations (e.g., EU directives including RoHS, WEEE, REACH, and China RoHS)
    • Assist clients with green marketing and ensuring product labeling complies with relevant environmental labeling regulations, such as the Green Mark, energy labels, US Energy Star, and 80 PLUS.
    • Improve product energy efficiency and continue ISAE 3000 assurance approval to provide clients with product energy saving solutions​​​​​
