Carbon Emission Management 305-1 to 5

In recent years, the global greenhouse effect has caused ozone layer depletion and extreme climate conditions. Cameo Communications actively responses to global issues and government policies by conducting greenhouse gas inventory and establishing inventories for the Tainan factory. Cameo Communications categorizes greenhouse gases by emission source into direct and indirect emissions. Direct emissions are generated from refrigerants used in factory utility equipment, carbon dioxide fire extinguishers, vehicle fuel, and power generation equipment. Indirect greenhouse gas emissions come from purchased electricity, all purchased from Taiwan Power Company, as well as upstream indirect emissions from electricity。

To reduce greenhouse gas emissions or increase greenhouse gas removal for sustainable management and fulfilling social responsibility, Cameo Communications has planned energy-saving and carbon reduction measures since the Tainan factory began operations in 2021. Compared with the base year 2021, carbon emissions decreased by 145.101 metric tons CO2e in 2022. In 2023, the Company mainly focused on carbon information disclosure and reporting, reducing carbon emissions to 649.186 metric tons CO2e compared with the base year2021, achieving year-over-year reductions in carbon dioxide emissions. In 2024, as the Hsinchu office was added, the base year is reset as 2024. The Company will continue planning related energy-saving and carbon reduction measures to respond to customer requirements and global carbon reduction issues。

Cameo Communications’ product lines in general is relatively simple. The Company does not emit ozone-depleting substances (ODS), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOC), or other harmful gasses, thereby reducing its impact on the planet。

Water And Wastewater 303-1 to 5

Current status of water resources

According to ESI (Environment Sustainable Index) statistics, Taiwan is among the world’s top 18 water-scarce countries. Additionally, scenario analysis done using the Aqueduct tools from the World Resources Institute (WRI) shows that in 2030, the region where Cameo Communications is located faces a 10-20% risk of water shortage. Although there is no immediate obvious water shortage risk, to respond to Taiwan’s water conservation initiatives, the Company actively cooperates with various water resource management measures. In 2024, water withdrawal was 20.71 million liters, water discharge was 16.57 million liters, and water consumption was 4.14 million liters。

The water source of Cameo Communications’ Tainan factory is tap water supplied by Taiwan Water Corporation, primarily used for general domestic wastewater and production purposes, including process water, product cleaning, air conditioning cooling systems, and waste gas and wastewater treatment。

To conserve water resources, all restrooms in the factory are equipped with water-saving toilets. Replacement of related water equipment prioritizes water-saving designs. The Company continuously evaluates water conservation measures such as recovering discharge water for use in air pollution control equipment scrubbing towers, recovering pure water waste for cooling tower use, recycling process wastewater, and developing low water consumption production technologies, continuing to contribute to sustainable development。


Wastewater management

Cameo Communications has very strict control requirements for wastewater. The factory conducts water quality tests on the discharged domestic wastewater twice a week. The Tainan Industrial Park Wastewater Treatment Plant dispatches personnel twice a month to sample and test the quality of the treated domestic wastewater discharge (SS, COD, pH value, etc.) to ensure that the discharged water does not exceed emission standards。

Note: Wastewater discharge volume refers to domestic sewage。

Waste treatment

For waste output, Cameo Communications adheres to the principles of waste recycling and maximum utilization, minimizing output as much as possible. Waste treatment focuses primarily on resource recycling and reuse, with final disposal as a secondary option. Control measures require proper waste sorting to avoid random disposal of waste that causes treatment problems. Additionally, there is waste source control where waste generated in manufacturing processes is categorized by nature: waste paper, waste plastic trays, and waste plastic, waste plastic cable ties, waste PE films, scrap iron, scrap aluminum, scrap hardware, waste hardware mixed wires, etc., implementing classified recycling. In 2024, hazardous waste weight was 6.74 metric tons. The Company also advocates reducing paper waste from paperwork, printing general documents on both sides when possible or using blank sides of discarded documents。

Currently, the Tainan factory’s commissioned waste treatment methods include small amounts of chemical treatment, incineration, physical disposal, and reuse. All cooperating waste collection vendors are legally licensed collection institutions。

The waste generated by the Company includes general industrial waste (incineration treatment) and hazardous industrial waste (incineration treatment and physical treatment)。

Waste solvent drums (C-0301 solid) and waste solvents (C-0301 liquid) generated from manufacturing processes from steel plate cleaning to wave soldering furnace procedures, PCB circuit board scraps (E-0217) generated from automatic cutting to component placement/insertion, and non-process generated waste wood mixture (R-0701), are all commissioned to qualified licensed vendors for collection and disposal. The total weight of scrapped products and electronic waste was 162.88 metric tons, in which a weight of 156.14 metric tons was recycled and reused, achieving a 96% recycling rate。

Environmental Compliance and Control

To prevent and mitigate environmental impacts generated from business operations, Cameo Communications employs dedicated environmental protection personnel in accordance with legal requirements. In 2018, the Company implemented the ISO 14001:2015 Environmental Management System, adopting the PDCA (Plan-Do-Check-Act) operational cycle to ensure continuous improvement of environmental performance。

The Company makes every effort to address deficiencies identified during inspections by competent authorities, demonstrating full commitment to corrective actions and compliance with all applicable environmental regulations. Relevant improvement objectives are established, and the effectiveness of corrective measures is reviewed regularly to ensure ongoing compliance。
