    Delta is dedicated to fulfilling its business mission "To provide innovative, clean and energy-efficient solutions for a better tomorrow." While developing its business, it attaches importance to symbiosis on Earth. Delta aligns its energy conservation strategy with its business development and extends its relevant experience to all parts of the world in line with global sustainable development goals:

    • Implement sustainable production: Set reduction targets to reduce the impact of plants and products on the environment
    • Promote the development of renewable energy: Actively develop renewable energy solutions and increase the ratio of renewable energy use
    • Respond to climate change: Identify climate change risks, enhance competencies to adapt to climate risks, and mitigate possible climate risks
    • Promote the concept of green buildings: Apply Delta's energy-saving solutions to green buildings
  • Delta’s smart and energy-saving LED lighting
    In 2022, Delta’s production sites in Dongguan and Wujiang obtained UL2799 Platinum certification by attaining a 100% diversion rate for waste.
    Delta Electronics’ Americas headquarters became the first LEED Zero Energy-certified green building in Fremont, CA.

Energy Management

Saved 41,126 MWh of electricity and reduced carbon by around 31,687 metric tons in 2022

Delta has long advocated and implemented environmental protection and energy conservation. All new plants and offices need to incorporate green building designs, and multiple energy-saving projects are actively promoted within the plants, offices, and data centers as it continues to achieve its goals and set new milestones in energy conservation.

  • From 2011 to 2022, each primary production plant has continued to implement energy conservation and carbon reduction measures (see the table below). The company put 309 energy conservation projects into practice in 2022 and saved approximately 41,126 MWh of electricity, equivalent to approximately 31,687 tons CO2e. Delta implemented a total of 2,826 energy saving projects from 2011 to 2022 with an estimated 355,330 MW of electricity saved, equivalent to a reduction of 276,766 tons CO2e.

Water Resource Management

Saved 108.8 megaliters of water

Delta has long been committed to improving water resources management measures and pursuing maximum water efficiency for its plants. In addition to prioritizing the use of water-saving equipment and devices, Delta strives to increase the water recycling rate, reduce waste water, and implement awareness-raising activities. Delta is committed to reducing its overall water intensity by an additional 10% by 2025, using 2020 as the base year.

  • Water Productivity Intensity at Plants: In 2022, the WPI of the overall production plants was 366 metric tons/million USD, a decrease of 21.3% compared with 2020.
  • Water Consumption Intensity at Buildings: In 2022, the WCI of seven buildings was 16.9 metric tons/Capita, a decrease of 23% compared with 2020.

Establishing Risk Assessment Mechanisms

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 risks of droughts derived from climate change. Delta uses the Aqueduct Water Risk Atlas developed by the World Resources Institute (WRI) to identify the risks of Delta's supply chain and global operation sites. We scored each risk based on the risk elements and the 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.

Water Consumption Review

A total of 37 new solutions for production sites and buildings have been implemented in 2022, including: rain water retention and reuse , condensate recycling, outlet pressure control, and equipment adjustment and improvement, saving a total of 108.8 ML of water consumption.

Waste Management

Reduced 1,480 metric tons of waste

Delta actively strengthens waste management measures, implements reductions from the source, increases the rate of resource reuse, and promotes closed-loop recycling to maximize resource utilization. Delta pledges 100% waste diversion rate by 2025.

  • In 2022, Delta's production sites in Dongguan and Wujiang obtained UL 2799 Platinum certification by attaining a 100% conversion rate for waste.
  • Delta continues to promote waste reduction measures, and a total of 61 waste reduction projects were implemented at overall production plants and buildings in 2022, including: recycling of packaging materials, adjustments of parameters to reduce the use of solvents, and sludge moisture content reduction, which resulted in a total of 1,480 metric tons of waste production savings.
  • Waste reduction reduced processing expenses by approximately 0.4 MUSD and the income from waste recycling totaled 16.193 MUSD.

KPI


  • Waste Diversion Rate

    Waste diversion rate = (reuse + reduce + recycle + thermal technologies + anaerobic digestion + biofuel + composting) / total mass discarded material

  • International Certification and Implementation

    Delta introduced UL 2799 zero waste landfill certification at Delta's Dongguan plant in 2019 and we have continued to improve waste monitoring, recycling, and reduction. We worked with suppliers on projects to gradually increase the resource recycling rate and expand the implementation to plants across the globe. In 2021, Delta's production sites in Dongguan and Wujiang obtained UL 2799 Platinum certification by attaining a 100% conversion rate for waste. We shall continue to pursue the goal of zero waste landfill for all Delta operations.

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. Delta plants have quantified value chain collaboration and overall effectiveness. The total amount of waste generated was 69,064 tons, and the total amount of all waste diverted was 68,403 tons, with a diversion rate* of 99%.

*Waste diversion rate = reuse + reduction + recycling + waste energy recovery + anaerobic digestion + biofuel + composting) / total weight of waste generated; of which, the percentage of waste energy recovery must be less than 10%.

Implementing Waste Management

Statistically, the total weight of waste at overall production plants processed by qualified disposal institutions was approximately 49,272 tons in 2022, of which, non-hazardous waste accounted for 45,352 metric tons (92%), and hazardous waste accounted for 3,919 metric tons (8%).
