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.
