Environmental and Resource Management

Management System

To stay close to the broader and macro environmental trends, CTCI has taken into account multi-faceted environmental aspects within its business objectives by introducing the ISO 14001:2015 Environmental Management System. To facilitate its effectiveness and help us identify risks comprehensively.

Energy

we regularly compile the performance statistics each year and report them to the President. The aim is to analyze the energy efficiency of operations by observing the changes and trends over the years. We then use the results to formulate and implement relevant policies, and use them as reference when setting carbon reduction and energy-saving targets in the future, gradually leading to the final achievement of low-carbon vision. CTCI will buy 27% renewable energy in 2023.
2025：45% renewable energy (Headquarters will use 85% renewable energy.)
2027：55% renewable energy (Headquarters will use 100% renewable energy.)
2032：91% renewable energy (Headquarters and domestic sites will use 100% renewable energy.)
2050：100% renewable energy (Headquarters and all sites)

Materials

All resources on Earth are limited. In each of our project, we always carry out precise calculations to understand the minimum amount of resources and their costs for a given construction project to prevent waste and unnecessary use of materials, so we can realize CTCI's highly effective resource management. During the material selection stage, we would carry out assessment with respect to environmentalfriendliness. The procurement of renewable materials helps us reduce resource consumption and environmental pollution. For the same reason, we support suppliers who carry out environmental management themselves and encourage them to develop and produce renewable materials. In addition, in determining which kind of building materials we should use, CTCI takes into account factors such as durability, maintainability, VOCs, hazardous substances, and radiation hazard. Furthermore, by using the newly-introduced life cycle cost analysis software (EEA), we can calculate energy consumption and the costs incurred within the entire life cycle.

Water Resources

Water consumption of the headquarters building in 2021 has reduced by 6.3% compared to that in 2020, reaching our preset reduction target.

Air Pollution

All CTCI staff on construction sites need to go through trainings on the requirements of Air Pollution Control Act before work commences, and must ensure that they fully understand air pollutants emitted need to meet standards.
▼ Preventive Measures against Air Pollution at Construction Sites

Soil and Groundwater

Before a construction work begins, we draw up sewage plans. This is followed by stringent environmental monitoring during construction to control the quality of effluent released from the construction sites. No waste materials or pollutants are allowed to be disposed of into water bodies or into designated distances from water bodies.

Waste

The general waste disposal method of the headquarters building is incineration. The amount of waste generated in 2021 is 56.3 metric tons, down 4.2 metric tons from a year earlier. Paper, metal, plastic, and food waste are all recycled. In response to the increasing amount of lunchbox waste during lunchtime, we launched the recycling of paper and plastic lunchboxes at lunch time. The most significant source of waste is construction waste. In principle, CTCI aims to minimize waste generation within construction sites and sets a reduction target to improve management and prevent waste of materials.

Prevention & Control of Noise

"In consideration of the health and safety of the operators and the construction quality, CTCI prioritizes the use of lownoise machinery, equipment, vehicles, and appliances. Highnoise operations are performed away from the construction sites whenever possible or to be performed by contractors. When circumstances demand the use of equipment classified as ""noise-prone"" by the government, we would always apply for permits before carrying out installation and operation work. Pile driving is conducted using noiseless methods when there are concerns about noise pollution, or is to be done at appropriate hours of the day. Nighttime construction would be avoided whenever possible. Drivers of vehicles outside construction sites need to follow instructions and are audited regarding the potential generation of noise by said vehicles.
They are required to drive on designated routes, in the designated time, with designated speed limits, and with noisereduction equipment installed."

Transportation

When selecting transportation contractors, CTCI prefers the ones who share our vision. We prefer those who have ISO 14001 Environmental Management Certification. To reduce the environmental impact from transportation, we use local equipment and materials whenever possible and procure locally to reduce transportation distance and conserve energy. We prioritize low-carbon and low-pollution forms of transportation. For example, energy-saving sea transportation is preferred over air transportation.

Biodiversity

CTCI's engineering design takes into account the potential negative impacts on local species, habitats and ecosystems. While implementing the project, we insist to select proper locations, circumvent important protected zones and special habitats, and avoid endangering local endemic and endangered species. We promise that, while conducting our project, we would reduce the interference to the ecosystem, conserve the environmental quality, and protect the ecological area and creatures. We shall regularly monitor the environmental factors such as noise, vibration, air, and drainage water at the construction site to ensure the maintenance of the original habitat of organisms. CTCI formulates response and pressure indicators to ensure the actual implementation progress in line with our commitment and extends this commitment, performance indicators, and objectives to suppliers at and above the first tier
