Environment
Climate change and energy management are vital for PHIHONG's sustainable development. We analyze, control, and reduce greenhouse gas emissions annually by 4.2%, striving for net zero emissions by 2050 to actively combat climate change.

PHIHONG is practicing green design and has implemented this policy throughout its main production facilities. While developing high efficiency and high-power density power supply products, we are strengthening the management through regional power usage monitoring systems in the manufacturing process.

Note: Phihong’s manufacturing focus has gradually shifted production to Vietnam over the past 2 years. The third factory in Vietnam commenced operations in 2022, leading to a significant increase in energy consumption. Taiwan serves as the research and development operation center and does not have production lines, therefore it is not included in the energy consumption calculations.

Note 1: The heat value and emission coefficient for Taiwan are sourced from the Ministry of Economic Affairs Energy Bureau’s “2019 Electricity Coefficient” published on July 20, 2020. The heat value for purchased electricity is 860 kcal/kWh.
Note 2: The heat value and emission coefficient for China are sourced from the Ministry of Ecology and Environment of China’s “2019 Regional Grid Baseline Emission Factor.” The conversion coefficient for the Southern Region grid is 0.8042 metric tons CO2e/MWh. The emission coefficient for gasoline, diesel, and natural gas is derived from the original IPCC coefficients multiplied by the fuel heat value. The fuel heat values are sourced from the National Standard of the People’s Republic of China GB/T2589-2008 “General Rules for Calculation of Comprehensive Energy Consumption.” Gasoline has a heat value of 14,110 kcal/L, diesel has a heat value of 10,200 kcal/kg, and natural gas has a heat value of 8,500 kcal/m3.
Note 3: The heat value and emission coefficient for Vietnam are sourced from the IPCC National Greenhouse Gas Inventory Guidelines (2006) for purchased electricity. The coefficients for gasoline and diesel are sourced from the Cross Sector Tool, with gasoline having a heat value of 0.0447 GJ/kg and diesel having a heat value of 0.0455 GJ/kg.
