Environmental Protection Policy
The group is committed to advancing environmental policies and establishing relevant plans, goals, and management practices. We actively train and promote advanced environmental protection technologies. Our production bases, including Dongguan Wieson, Jiangsu Wieson in mainland China, and Wieson Technologies in Taiwan, have all obtained ISO 14001 Environmental Management System certification (Note). Through the implementation of these systems, we aim to build employees' environmental protection awareness and behaviors, achieve environmental protection results, conserve energy, reduce emissions, and lessen the environmental burden to ensure sustainable business practices. We are dedicated to protecting the Earth through green production and healthy living.
Our environmental protection policy includes: resource development, rational utilization, strict compliance with laws and regulations, pollution prevention, integrated management, environmental protection, and continuous improvement. All Wieson employees are actively engaged in protecting the environment and are committed to controlling and eliminating the use of restricted substances.
In the future, we will continue to promote ISO 14001 and stay updated on environmental protection regulations, revising our operational procedures and taking timely actions as needed. We will also actively promote legal knowledge, provide training on environmental protection regulations to employees, and enhance their awareness of environmental protection, ensuring compliance with relevant regulations and integrating them into daily life.

Raw Material Usage
Our connectors and wireless products primarily serve the 3C consumer electronics sector. From R&D and design to procurement and production, environmental safety and product reliability are our top priorities. We select materials from reputable manufacturers to ensure product compliance.
In 2023, our group's production bases procured raw materials, with the exception of some plastics, which were directly sourced. All other components were purchased from suppliers within the supply chain system.

Greenhouse Gas Emissions
Extreme climate anomalies caused by global warming have significantly impacted and threatened human living conditions. Countries worldwide are increasingly addressing carbon emissions issues, with specific goals outlined in agreements such as the Kyoto Protocol, the Paris Agreement, and the recent Glasgow Climate Pact and COP 27 resolutions. Nations have implemented policies to achieve net-zero emissions. Our company recognizes the urgency of climate risk management and has progressively initiated various greenhouse gas management efforts to ensure a sustainable future for the planet.
Our energy use primarily includes power for production and office operations, with energy mainly sourced from purchased electricity. To reduce greenhouse gas emissions, we began conducting greenhouse gas inventories in 2021. Relevant departments and personnel have undergone training, and we have set carbon reduction targets, monitored progress, and overseen efforts to reduce energy consumption, improve energy efficiency, and minimize environmental impact. We are committed to making significant efforts to combat climate change.
In 2023, to promote sustainable development and meet international standards, we engaged an external ESG consulting team. They worked with our ESG teams in Taiwan, Dongguan, and Jiangsu to conduct a carbon inventory and complete third-party verification. We prepared a greenhouse gas inventory report, which provides insight into our greenhouse gas emissions, responsibilities, and risks. This process also allowed us to identify the most cost-effective reduction opportunities, enhance energy and material efficiency, and develop new products and services to reduce greenhouse gas emissions from our customers and suppliers.
At our Jiangsu Wieson production base, solar power systems were installed on the factory rooftop in 2022 as per customer requirements, with electricity generation starting from October 1 of the same year. For the period from January 1 to December 31, 2023, the total power generated was 1,222,278 kWh, with 1,087,178 kWh used on-site and the remaining 135,100 kWh fed into the grid. Through this mutually beneficial cooperation with customers, Jiangsu Wieson reduced its emissions by 605.341 tons of CO2 equivalent in 2023.
At our Dongguan Wieson production base, solar power systems were similarly installed on the factory rooftop in 2022 to meet customer requirements, with electricity generation starting from January 2023. For the period from January 1 to December 31, 2023, the total power generated was 1,127,484 kWh, with 1,050,124 kWh used on-site and the remaining 77,360 kWh fed into the grid. This collaboration with customers resulted in a reduction of 623.984 tons of CO2 equivalent emissions for Dongguan Wieson in 2023.
