5.2 Resource Sustainability Management

5.2.1 Resource Sustainability Management

Our water is mainly from water companies without using groundwater or other water sources. The water in each office building and service site is only used by employees and some clients, without significant negative impact on the water source. The used domestic sewage is discharged from the sewers and treated through the sewers. In 2023, the scope of the inventory was expanded to cover the entire company, with 2023 as the baseline year. The targets are 1% reduction in 2024 and 2% reduction by 2030. In 2023, water consumption per capita decreased by 3.46% compared to 2022.

5.2.2 Waste Management

The waste in PSC’s building mainly comes from domestic waste. To be friendly to the environment, we have continued to reduce waste and implement a waste classification system for recycling for many years and classify waste as general waste, recyclables, and kitchen waste. Employees sort their waste by themselves in the centralized waste temporary storage area, and the building property management company will put it together. General waste will be transported to an incineration plant by a qualified waste transport company, and the recyclable resources will be handled by recyclers. Confidential documents are destroyed depending on each unit’ retention period in compliance with the principle of security and confidentiality to prevent the leakage of client data.

The head office building began to weigh the waste in 2020 to strengthen waste management, and we added significant indirect emissions in addition to the existing direct emissions and indirect emissions in alignment with ISO 14064-1:2018 Greenhouse Gas Emission Inventory. In 2023, the verification scope was expanded to include branches and subsidiaries in Taiwan, achieving 100% inventory coverage. Waste reduction targets were set with 2023 as the baseline year, aiming for 1% reduction by 2024 and 2% reduction by 2030.

In 2023, sustainable environmental education-related advocacy amounted to 33,888 times, totaling 2,824 hours.。

5.2.3 Circular Economy

PSC promotes the concept of a circular economy by opting for leasing instead of purchasing, which reduces the environmental impact of products and waste, including company vehicles and office equipment. Office machines are set to energy-saving modes, and initiatives such as double-sided printing, paperless meetings, and multi-page printing are encouraged to reduce carbon emissions from printing. Company vehicles are gradually being replaced with hybrid vehicles based on lease terms. In 2023, hybrid vehicles accounted for 61.5% of the fleet, with the goal of reaching 75% by 2025 and 90% by 2030.

To reduce environmental impact, PSC aligns with government environmental protection policies in promoting green office practices. In addition to reducing the use of plastic and waste, promoting paperless meetings, and reducing paper usage, the Company also encourages the use of eco-friendly cups and utensils, disposal of tissues in toilets, and green consumption to foster environmental awareness among employees in their daily routines. Starting in November 2023, we began using reusable containers for meeting lunches, actively reducing the use of disposable tableware.
