In response to the crucial environmental issues such as global energy crisis and the urgency of reducing greenhouse gas emissions, CWTC strives to promote the evaluation of production line machines. By doing so, we hope it can help to reduce the consumption of energy resources as well as to discuss and improve the energy efficiency of the factory’s utility system. Each year, we will set energy saving goals and implementation plans by integrating the proposals for the measurement of energy saving, tracking the result process regularly and controlling the implementation results.

In line with the government encouragement of renewable energy use, we have installed additional solar panels with a capacity of approximately 98 kWp in the Kaohsiung plant in 2020, which helps CWTC to fulfil its responsibility as a global citizen and a corporation.


First category

Direct green house gas emissions

*Mainly come from generators, refrigerator, air conditioners, vehicles, stackers, etc.
*Gas emissions count for approximately 8%
*Main gases are CO2、CH4、HFCs The target reduction in 2021 is 5%.

Second category

Indirect green house gas emissions

*Mainly come from outsourced power
*Gas emissions count for approximately 92%
*The target intensity of greenhouse gas energy in 2021 is to increase by 5%.

Third category

Other indirect green house gas emissions

*Mainly come from outsourcing transpiration, employee commuting, waste disposal, etc.
*Our current goal for this category is to run the investigation regulary.


CWTC is located in the Nanzi Processing Zone. Water that CWTC uses is entirely from the Taiwan Water Supply company so it will not affect the head-water point. Because of the limited water resources we have in Taiwan, the company implements water resource recovery facilities that pass the cooling tower wastewater through the filtration system to improve water efficiency as well as to reduce water consumption.

Furthermore, the water that the overseas plants use comes directly from the local water company. In line with water saving and recycling policy, the Suzhou plant prioritized the installation of a reclaimed water system that can recycle and reuse the production water with a certain water quality in the production line. The system is mainly for processes that require large water consumption such as washing and electroplating. By recovering secondary water and then processing it, the overall internal water cycle of the company can reach a certain standard, thereby reducing the supply of raw water and achieving the goal of water conservation. In view of the water-saving benefits that has brought to the Suzhou plant, we are currently planning to install the reclaimed water system in each plant.



The responsibility of the waste management officer in CWTC is to manage the waste disposal by dividing into three different categories including “general industrial waste”, “hazardous industrial wastes”, and “resource recovery”. Then, follow the waste classification guideline and the storage principle as well as entrust legal waste removal treatment. Since some waste has the value of recycling and reuse, we delegate legal institutions to reprocess the products to eliminate pollutants and waste. By doing so, we can reduce the costs of production and protect the environment.

CWTC upholds the concept of "giving back to the society", and deeply understands "the limited natural resources" and "the importance of environmental protection". As a result, we promise to protect the environment in all aspects of business operations, products, and services.

  1. We use raw materials and clean the production chain to reduce pollution and the impact of product supply to the environment.
  2. We comply with relevant environmental protection laws and regulations and other environmental responsibilities that the subsidiary companies should follow as well.
  3. Through environmental goal setting, regular audits, and management reviews, CWTC improves continuously and enhance the environmental performance.
  4. CWTC adopts the risk control technology to reduce the risk of harm to stakeholders effectively and continuously strengthen the interactive relationship with contractors, suppliers, etc.
  5. CWTC is able to protect natural resources through effective use and waste reduction programs.
  6. We reduce and prevent the impact of harmful substances, wastewater, and exhaust gas on the environment to protect employees and the environment.
  7. We raise the product quality to reduce the waste volume.
