Energy Management

In response to the global development trend of climate governance, Nuvoton Technology has extended its carbon reduction goals and issues from the environmental protection aspect in the past to the industrial and energy transitions. Nuvoton Technology introduced the ISO50001 energy management system in 2022, which is scheduled for verification in 2023. Through the establishment of the PDCA (Plan-Do-Check-Action) mechanism and establishment of related standards and methods, the Company strives to improve energy use efficiency, elevating its energy performance to the optimal level. Through the promotion of energy management policies and target plans, it aims to achieve reductions in energy use and costs as well as greenhouse gas emissions, so as to fulfill the goals of sustainable business and environmental friendliness.

The energy conservation and carbon reduction projects promoted by Nuvoton Technology in 2022 mainly focused on the installation of renewable solar energy and fluorinated gases (F-gases) reduction equipment to the processes. It is projected to complete 8% of the contracted capacity of renewable energy in 2023 (Projected investment 50 million NT dollars, 880,000 degree produced annually). The installation of first fluorinated gases reduction equipment completed at 2022, which is expected to reach a 20% reduction of fluorinated gases in the processes upon its official operation, with increasing reduction amount forward-looking.

Energy Conservation & Carbon Reduction Management

Nuvoton Technology mainly focuses on IC design and sales and foundry services. The source of energy used at present is primarily purchased electricity, accounting for about 97.2% of the total energy consumption, followed by gas (natural gas and liquefied petroleum gas), for about 2.8%, and fuel oils (diesel and motor gasoline), for less than 0.1%. The electricity is all purchased from Taiwan Power Company, without any use of renewable energy like geothermal energy, wind energy, solar energy, hydropower, or biomass energy. In 2022, according to the inventory of the actual electricity use, the electricity consumption was 72,294,038 kWh, which is equivalent to 260,258.54 gigajoules (GJ), dropped by 2.5% compared with the level of previous year. The total energy consumption was 267,811 GJ with an energy intensity of 13.72 GJ per million NTD, decreased by 27% from the previous year.

Greenhouse Gas (GHG) Management

To capture the status of GHG-related activities on the Company and stipulate the reduction targets and priorities, Nuvoton Technology has established the GHG inventory mechanism in alignment with ISO 14064-1 and the Guidelines for Greenhouse Gas Inventories of the Environmental Protection Administration, the Executive Yuan since 2009. The GHG emissions from the plants are inventoried regularly each year. Also, year 2010 is set as the base year for GHG emissions (Scope 1 and 2). To improve the credibility of the GHG inventory information and reports, as well as strengthen the data quality of GHG inventory, all the annual GHG inventory materials (Scope 1 and 2) are verified by a third-party verification body in accordance with ISO 14064-1 since 2009 to obtain the Verification Statement. Since 20201, scope 3 has been included in self-inventory and cerification process.
