Climate Adaptation
Implement Climate-related Financial Disclosure (TCFD) Framework

Under the impact of climate change, the world is increasingly facing severe climate disasters with affected regions and populations expanding gradually. Therefore, how to limit global warming to within 1.5˚C by the end of this century and take proactive actions is a common challenge for everyone. In response to international trends and stakeholders' concerns, SOLAR adopted the concepts and framework of the Task Force on Climate-related Financial Disclosures (TCFD) in 2022. By incorporating governance, strategy, risk management, and setting metrics and targets, SOLAR gradually assessed and clarified the risks and opportunities associated with climate change. Furthermore, SOLAR presented corresponding management measures to enhance our operational resilience.

Energy Management

In 2020, SOLAR began to introduce ISO 50001 energy management system at Guangxin Building in Solar Park. Due to the urgency and necessity of energy saving, in 2022, SOLAR expanded the sites of implementation of ISO 50001 energy management system, including three manufacturing sites in Taiwan (TTIP Plant, Solar Park, ESTP Plant), and we received reasonable assurance from SGS (impartial third-party). By systematically inventorying significant energy-consuming equipment, setting goals, proposing multiple energy saving action plans, reducing energy consumptions, and improving the efficiency in energy usage, SOLAR aims to achieve the goal of energy saving.

● SOLAR’s energy saving goal:
The annual amount of energy saving ≥1%

Effective Use of Energy

Efficient use of energy is essential to mitigate the impact of climate change, as the use of energy generates carbon dioxide and causes the greenhouse effect. Recognizing that energy management is a crucial part of business operations, SOLAR actively engages in energy saving initiatives, including the construction of solar energy facilities, the use of renewable energy and the continuous introduction of various energy-saving technologies and facilities.

SOLAR has established the Energy Management Committee, with the President serving as the Chairperson. The committee should hold quarterly meetings to regularly review compliance with regulations, track the progress of energy-saving action plans, and assess the effectiveness of project implementation. Furthermore, SOLAR takes a proactive approach to equipment procurement and design, conducting reviews to ensure the use of energy-efficient power components and controlling the energy consumption standards of newly acquired equipments. We also conduct energy audits to assess the energy consumption of current equipments, identify significant energy-consuming equipments, and review energy-saving improvement plans to achieve energy management objectives.

Use of Renewable Energy

SOLAR regards increasing the use of renewable energy as an important development strategy to reduce greenhouse gas emissions and continues to expand our solar photovoltaic system in our plant areas to promote renewable energy. We hadve installed solar panels with a peak power of 513.06 kWp on the roofs of Solar Park and ESTP Plant. Our PV system generated 385,308 kWh of power in 2022 and reduced 196 tonnes of carbon dioxide emissions. Furthermore, we installed solar panels with a peak power of 97.98 kWp at the motorcycle parking shed of TTIP Plant by the end of 2022. Since they did not start generating electricity in 2022, they were not included in the scope of this statistical analysis.
  • In 2023, SOLAR has made a new investment in solar photovoltaic systems, with the investment amount exceeding NT$25 million.
  • ISO 50001 Certificate

Greenhouse Gas Inventory and Management

SOLAR’s GHG emissions mainly come from purchased power and stationary combustion, which account for 96% of total emissions. In 2022, our GHG emissions under Scope 1 and Scope 2 amounted to 41,930 tonnes of CO2e, showing a year-over-year rise of 4.6%. Our GHG emissions under Scope 3 amounted to 208,105 tonnes of CO2e. Our data received reasonable assurance from BSI (impartial third-party) in 2023, as stated in the verification opinion statement.

Water Resources Management

Water is an indispensable substance to human survival. It is also an important lifeline to business operations. The lack of water resources has gradually become an important issue. SOLAR values water recourses management. We properly manage water intake and discharge of wastewater. In 2022, our water intake and wastewater discharge respectively reached 562.858 million liters and 307.343 million liters, with total water consumption of 255.515 million liters. In order to meet the discharge standards for ammonia nitrogen in wastewater in 2022, SOLAR made parameter adjustments in the existing wastewater facilities and treatment processes. As a result, there was a significant increase in water intake and discharge. To deal with this issue, we have initiated the planning and construction of the new wastewater treatment system. Our goal is to improve the effectiveness of water resource management in the future.

Waste Management

We have waste management system in place for treating the waste generated by three plants. In 2022, 7,060.99 tonnes of waste were generated, of which 4,289.67 tonnes (60.75%) were recycled and reused. Among the non-hazardous waste, the total volume of solid waste was 4,322.91 tonnes, of which 1,972.38 tonnes were recycled and reused, and 147.98 tonnes were incinerated with energy recovery.


Pollutant Emission Management

SOLAR conducts regular inspections of pollutant emissions in various processes, with all test results significantly below regulatory standards and achieving environmental performance goals.

Hazardous Substance Management

SOLAR ensures that our products adhere to international standards such as RoHS, REACH, SONY GP SS-00259, and others, while also meeting customer requirements. We have established procedures for managing prohibited and restricted hazardous substances to implement Hazardous Substances Free (HSF) management. From design to production, we rigorously control our processes to provide products that meet both regulatory and customer demands. Additionally, we fulfill customer requests by submitting relevant hazardous substance investigation forms and declarations, regularly updating third-party notarized testing reports, and achieving a 100% compliance rate.

ISO 14067 Carbon Footprint of Products

SOLAR puts very much emphasis on issues related to climate change and the development of products to mitigate it. Therefore, SOLAR continues to conduct carbon footprint inventory and verification of our products. Since 2022, SOLAR has obtained carbon footprint data for at least eight key products in order to identify the hot spots of carbon emissions within the organization, and then they will serve as the bases of improvement in carbon reduction.

The carbon footprint of the following products has been obtained:
