Management Performance

  • In 2020, the Group’s energy-saving and carbon-reduction actions reduced a total of 467.8 metric tons of CO2e
  • In 2020, the overall waste volume from the Group was reduced by 22.8% compared to the previous year
  • In 2020, the Group’s electricity consumption per unit of effluent treatment was reduced by 12.5% compared to the previous year
  • In 2020, the Group’s sludge reduction totaled 1,024.4 metric tons

CHC Group Greenhouse Gas Emission, Waste, Water Consumption by year

Note: Greenhouse gas emission amount has been certified by SGS Taiwan in 2019 and 2020. The greenhouse gas emission accounted for 55% and 52% of total emission in 2019 and 2020 respectively as stated in ISO 14064-1:2018 certification.

Management Strategies and Actions

CHC regularly reviews electricity consumption and greenhouse gas emissions, understands the trend and efficiency of operating energy use, is committed to reduction plans and equipped with flexible management strategies, and continues to work hard against global warming. The Group’s greenhouse gas emissions are caused by indirect emissions from outsourcing power purchases, mainly originating from the effluent treatment and reclaimed water plants of the Environmental Project Development Business (HDEC). Therefore, the company uses electricity consumption per ton of effluent treatment as a quantitative management indicator, and the evaluation indicator is based on the wastewater treatment plant in operation. Using 2019 as the base year (the indicator evaluation benchmark value is 0.32), CHC set the goal of reducing electricity consumption per ton of effluent treatment by 5% in 2023.

Measures taken to achieve the Goal:

1. Energy optimization evaluation of high-energy-consuming equipment
Inventory check and review the usage efficiency of high-power equipment in each operating site, evaluate equipment upgrade requirements or develop energy-saving operation plans, as well as draw up the corresponding replacement and maintenance plans.

2. Adjust, update, or install automatic control facilities
Automatic control systems such as time switches and smart controllers for facilities and equipment in the operating field have been installed for timely and flexible regulation in order to improve the energy utilization efficiency of the operating sites.

3. Plan and flexibly adjust the frequency and mode of equipment operation
Adjust the operation mode and frequency of the equipment in accordance with the equipment upgrade plan and changes in the surrounding conditions such as temperature and humidity. For example:
Suspend the operation of the water recovery pump at night, control the fluid level for wet wells, adjust the operating frequency of aeration equipment, etc.

4. Evaluation, implementation, and introduction of smart energy management system
Plan and build an energy management platform for each operating site, and use the smart monitoring system to automatically record, summarize, and analyze energy usage and trends to effectively control and track the energy management performance.

Achievements:

In 2020, the company completed a group-wide energy use inventory and analysis study report. The CEO convened several meetings with all members of the ESG Committee to discuss the Group’s energy management plan for the coming years, and at the same time discussed and established the above-mentioned quantitative management goals, which will be implemented and tracked continually. The actual value of the company’s management evaluation index in 2020 was 0.33 due to the pollution of influent water, which increased the workload effluent treatment and energy consumed. In this regard, CHC actively cooperates with the law enforcement actions of the competent authority and continues to monitor the influent water and to enhance efficiency of water treatment.

Environmental Education

Fengshan Water Resource Center

The landscape planning of the Fengshan Water Resource Center operated by the Group integrates with the surrounding wetland park and river corridor to create a place where water resources, environment, and ecological education can flourish together. It is the first educational park in Taiwan with reclaimed water as the main theme. In order to promote the importance of water resources conservation, a "Water Science and Technology Education Hall" has been set up in the park, which combines sound and lighting technology to introduce a 3D, parent-child interactive activity and a VR reality experience, allowing the public to experience the preciousness of every drop of water. In 2020, the Water Science and Technology Education Hall introduced various diversified environmental educational activities such as AIoT Experience Camps, Water Mommy storytelling series, Soaking in the Hot Summer, Frozen 2 movie appreciation, Memory of Fengshan, Travel to Japan in Nature, and so on. Through guided tours of the local culture and water culture of various countries, visitors get to explore the rich world brought about by water resources in an entertaining way. Through volunteer activities and visits to the reclaimed water plants and the Water Science and Technology Education Hall, the public learns about the current status, technology, and trend of water treatment. A total of 6 Water Science and Technology Education Hall environmental education experience activities were held throughout the year. A total of 28.5 hours of manpower were invested, and a total of 205 people participated. A total of 32 visits of guided activities for environmental education were completed throughout the year with 156 hours of manpower invested, and served a total of 886 people.

Tamsui Water Resource Center

Adhering to the core spirit of "Living with the Environment" and "Integration with Nature", the Group has established an educational institution advocating environmental protection and sustainable heritage within Tamsui Water Resource Center. The purpose is to promote the attitude of coexisting with the environment and allow the public to experience the importance of environmental conservation in order to take action to cherish the environment and resources. Tamsui Water Resource Center applied for environmental education facilities in 2020 and passed the certification in July 2021. Tamsui Water Resource Center continues to hold courses, train commentators, regularly adjust the course design plan according to the trend of environmental protection technology, actively convey correct and innovative concepts to participants, and strive to practice the spirit and ideals of the "hands-on environmental education". In 2020, there was a total of 3 self-organized environmental education experience activities conducted, along with 22.5 hours of manpower invested, and served a total of 70 participants. A total of 18 environmental education visits and guided activities were conducted, with 58 hours of manpower invested, and a total of 618 people were served.
