Every June and December are the Group’s environmental protection promotion months, aiming to educate employees on various energy-saving and carbon reduction policies. The Group also sets annual energy-saving targets to manage each production base, tracks emission reduction achievements, and publicly discloses them on the Company’s website. The Group conducts ISO 14064-1 greenhouse gas inventory and commissions SGS and BSI for third-party assurance. Due to changes in operational activities following the lift of pandemic restrictions, the baseline year has been adjusted.

Before DFMAfter DFM
Before DFM: The product is assembled by welding 8 steel plate components, requiring a total of 8 sets of molds. It weighs approximately 7.6 tons and uses 8 stamping machines (4 of 300 tons and 4 of 600 tons). Annually, 3,000 pieces are produced, consuming 142,200 kWh. The annual electricity usage results in 102.67 tons of CO2e emissions, and the molds contribute 18.772 tons of CO2e emissions.
After DFM: The product is assembled by welding 4 steel plate components, requiring a total of 4 sets of molds. It weighs approximately 5.35 tons and uses 4 stamping machines (3 of 300 tons and 1 of 600 tons). Annually, 3,000 pieces are produced, consuming 85,050 kWh of electricity. The annual electricity usage results in 61.42 tons of CO2e emissions, and the molds contribute 13.214 tons of CO2e. Each year, 57,150 kWh of electricity can be saved, equivalent to 41.25 tons of CO2e, and mold emissions can be reduced by 5.558 tons of CO2e.
Before DFMAfter DFM
DBefore DFM: The design drawing requires multiple angles, such as R25.4, R38.1, and R19.5, utilizing a total of 3 sets of molds with a weight of approximately 1.5 tons. 2 stamping machines of 110 tons each are also required. Annually, 14,400 pieces are produced, consuming 4,050 kWh of electricity. The parts require four stages of processing to be completed. The annual electricity usage results in 2.92 tons of CO2e emissions, and the molds contribute 3.705 tons of CO2e emissions.



After DFM: We recommend that customers standardize the use of R31.75 bending, which requires only one set of molds weighing approximately 0.6 tons and one 110-ton stamping machine. Annually, 14,400 pieces are produced, consuming 2,025 kWh of electricity. The parts only need three stages of processing, resulting in emitting 1.46 tons of CO2e, and the molds contributing 1.482 tons of CO2e. This change saves 2,025 kWh annually, equivalent to 1.46 tons of CO2e, and reduce mold emissions by 2.223 tons of CO2e.
