Sustainability

The Company implemented the ISO 14001 Environmental Management System in 2014, the ISO 50001 Energy Management System in 2016, and the ISO 46001 Water Management System in 2023, and has obtained third-party certification for all three. The 2025 ISO 14064-1 greenhouse gas inventory has been verified by a third party. All companies included in Chailease Holding’s consolidated financial statements have received verification/assurance from the British Standards Institution. Since the implementation of ISO 14064-1 in 2020, the scope has gradually expanded from Taiwan to China and other overseas regions, and now includes shared offices and URiDE short-term rental stations.

Chailease Holding’s Taiwan-based subsidiaries adhere to three key pillars—environmental sustainability, energy management, and water resource management. Through a planned and systematic management framework, the Company integrates the efforts of all the organizational units, set short-, medium-, and long-term environmental sustainability goals, and implements rigorous monitoring and tracking to continuously reduce the environmental impact of its operations, demonstrating a proactive commitment to aligning with international standards for environmental sustainability. The initial target is to reduce electricity consumption at the headquarters building by 20% by 2020, using 2015 as the baseline year. Due to the early achievement of our targets for upgrading energy-efficient lighting and other equipment, we have revised our goals to use 2020 as the baseline year. We aim to reduce electricity consumption by 2%, water consumption by 3%, and waste volume by 2% annually, as well as cut paper usage for photocopying by approximately 5%, with the goal of implementing reduction measures on a year-by-year basis. By adopting a planned and systematic PDCA management model and adhering to continuous improvement within the management system, we have successfully achieved tangible benefits from these improvements.

Carbon Emission

Chailease Holding has long conformed to official greenhouse gas reduction targets. By keeping an organization-wide GHG inventory, we can not only track our carbon emissions, but also formulate a GHG emissions reduction plan. Moreover, we submitted the SBTi commitment in 2024. As of the end of 2025, the relevant targets have completed the submission process. Subsequently, after the reporting period (January 2026), they were approved by the Science Based Targets (SBT) reviewThe emission base year is 2023, with a target to reduce greenhouse gas (GHG) emissions by 42% by 2030.


The fire extinguishers in the Taiwan headquarters building are all 10P-ABC dry powder fire extinguishers, and the sea dragon fire extinguishers containing chlorides and bromides that will affect the earth's ozone layer are not used. The main unit of the air conditioner used on the floor adopts the type of refrigerant R22; the water dispenser adopts R134a and R600a environmentally friendly refrigerants.

Environmental Protection Efforts in Taiwan


Waste and Wastewater

To promote environmental protection and reduce waste, all offices in Taiwan and overseas have implemented a system where employees sort waste and recyclables, which is then verified in detail by local property management staff. The weight of the waste and recyclables is measured and recorded using scales, and the materials are subsequently collected by government-licensed waste disposal companies. In 2025, Chailease Holding generated a total of 568.06 metric tons of waste. Of this total, approximately 101.23 metric tons were generated in Taiwan, with17.70 metric tons recycled and 83.53 metric tons (including food waste) not recycled. The total carbon emissions from the incineration of non-recycled waste amounted to29.31 metric tons of CO2e.

The headquarters’ water supply comes entirely from the Taipei Water Department; no groundwater or water from other natural bodies of water or organizations is used. The water is intended solely for employee use, and the resulting domestic wastewater is discharged directly into the sewer system. At overseas subsidiaries, wastewater is discharged directly into the building’s underground sewer pipes and then released into rivers and the ocean; therefore, there is no significant negative impact on water sources.

Energy and Water Management

According to statistics on resource usage across the Company’s various operational sites, Chailease Holding’s total electricity consumption was 15,647,624 kWh, of which 8,425,175 kWh (30,330,628.55 MJ) was consumed in Taiwan. By 2025, due to the expansion of operational sites, per capita electricity consumption in Taiwan increased by 13% compared to the base year. By 2025, Taiwan had already supplied 908,684 MWh (3,271 GJ) of green electricity, and this figure will gradually increase each year to achieve 100% green electricity usage island-wide by 2030.

In 2025, Chailease Holding’s total water consumption amounted to 63,006.95 cubic meters. Water withdrawal in Taiwan, based on water utility bills, totaled 33,383 cubic meters (33.38 million liters). Water consumption per capita—considered immaterial due to the Company’s office-based operations—decreased by 39% compared with the previous year. The Company continued to implement various energy-saving and carbon reduction measures and awareness initiatives across its operating locations to enhance employees’ environmental awareness and achieve measurable improvement results.

Internal Carbon Pricing

In response to the global net-zero trend, the Company initially set a goal of reducing the total electricity consumption of the headquarters building by 20% by 2020, with 2015 as the base year. However, because of a complete renewal of power-saving lamps and other equipment, the target has been achieved ahead of schedule. In order to continue improvement, we promoted environmental protection and raised awareness of energy conservation and carbon reduction, changing the target setting to 2020 as the base year, promoting the reduction plan year by year, and integrating the internal carbon pricing system into the management mechanism to drive behavioral change within the Company.

Chailease Holding first introduced an internal carbon pricing system for its Scope 1 and Scope 2 greenhouse gases, utilizing the spirit of user-pay, and levied a carbon fee on each business department based on the greenhouse gas emissions from energy consumption, which is currently priced at approximately NT$10,119/tons of CO2e, prompting each department to take actions to reduce carbon emissions through the fee. To promote low-carbon financing, in the fourth quarter of 2024, we adopted the spirit of internal carbon pricing and included the Scope 3 financing business in Taiwan in our internal carbon pricing considerations. For financing cases targeting high-carbon-emission industries, we calculated the amount of carbon emissions of the credit customers based on the proportion of their capital investment, and levied an additional carbon emission cost on the business units, and the carbon fee is currently set at NT$600/tons of CO2e.

All fees collected are used as carbon funds to promote internal carbon reduction efforts, including carbon fund management, organizing environmental activities, and purchasing energy-saving equipment and green energy. Through the introduction of internal and external carbon pricing systems, the Company will gradually change its internal planning and decision-making on performance improvement and financing of customer industries, and gradually move toward the goal of net-zero emissions

 

In accordance with the “Code of Practice on Corporate Social Responsibility” approved by the Board of Directors in 2011 and the “Operational Procedures and Behavior Guidelines for Integrity Management” in 2014, Chailease Holdings' supplier management policy explicitly stipulates the legality and integrity of supplier management policies and requires suppliers to follow relevant regulations on issues such as environmental protection, occupational safety and health, or labor human rights, and to avoid dealing with those in conflict with the CSR policy. If a supplier is involved in a policy violation that has a significant impact on the environment and society in the supply source community, we may terminate or cancel the contract at any time.

The “Supplier Social Responsibility Code” was established in 2014 to regulate suppliers to meet ethical standards, respect labor and human rights, and environmental sustainability. In 2015, a new “Supplier Code of Conduct” was established to include violations of integrity contracts. In 2021, the revised name was changed to “Supplier Corporate Social Responsibility Code.” In 2022, rename “Supplier Human Rights and Environmental Sustainability Clause and Integrity Commitment” which added Integrity Commitment Clause. in the hope that suppliers will work together to achieve the goals of good ethical standards, respect for labor and human rights, and environmental sustainability, and the content of the code includes labor, environment, safety and health, anti-corruption & anti-bribery, ethics and management standards for sustainable development. The main types of suppliers are consulting services, interior design services, information technology services and energy technology services.


Implementation Measures
  1. Holding communication meetings: Holding periodic communication meetings with suppliers to promote CSR policies.
  2. Education and training promotion: Provide education and training to assist suppliers in building CSR management capabilities.
  3. Targeted suppliers: Suppliers with whom the Company's cumulative transaction amount reaches NT$1 million or more in the current year and who sign the “Supplier Human Rights and Environmental Sustainability Clause and Integrity Commitment”.
Implementation
  1. The “Supplier Corporate Social Responsibility Guidelines” were revised and renamed as the “Supplier Human Rights and Environmental Sustainability Clause and Integrity Commitment.”
  2. Produced supplier education and training handouts and invited suppliers to participate in online courses.
  3. Chailease Holdings and its subsidiary Taiwan suppliers signed the “Supplier Human Rights and Environmental Sustainability Clause and Integrity Commitment”, with a 100% completion rate. A total of 154 suppliers signed the agreement, representing an increase of 38 compared to 2024.
  4. ESG self-assessment questionnaires were distributed to suppliers with transaction amounts exceeding NT$1 million, totaling 96 suppliers, with a 100% completion rate.
Evaluated Items and Results

The average score of the ESG self-assessment survey was 70. Based on the performance of suppliers, those who did not achieve 50 points were analyzed for scale and industry attributes, and further subdivided into standard conditions for subsequent evaluation of counseling and improvement, and cooperation will be terminated if significant negative impacts are identified. At present, none of our suppliers are engaged in child labor, major labor cases, or major environmental impacts.

Chailease Energy-Promoting the positive cycle of solar photovoltaic supply chain

In order to drive the positive cycle of the solar power industry and the supply chain, and to bring into play the sustainable impact of the responsible supply chain, Chailease Energy, a subsidiary of Chailease Holdings, requires its suppliers to fulfill their corporate social responsibility, to provide a safe working environment, to value human rights in labor relations, to comply with ethical operation, and to promote environmental protection.

In early 2022, we also revised our supplier and partner selection criteria, institutionalized the promotion and evaluation of supplier and partner qualifications, and included environmental management, social commitment and Company operations with reference to the positive ESG list items. The written review is combined with on-site evaluation, scoring and evaluation to select suitable suppliers and partners as the priority reference for cooperation selection. We also require suppliers to sign a commitment letter and conduct occasional visits to track the continuous improvement in order to improve the performance of supply chain management and move forward together towards the goal of sustainable development.

We invest in sustainability management, including polysilicon and silicon crystals in upstream industries; solar cells and modules in midstream industries; and suppliers and construction materials and equipment in downstream industries, including system construction EPC (Engineering, Procurement, and Construction) manufacturers, aluminum brackets, steel structures, electrical and mechanical panel manufacturers, monitoring manufacturers, and other peripheral related industries.

Following an ESG project evaluation for the 91new partners added this year, the average score was 40. Further analysis of their performance found that each company is operating legally and in compliance with the law. There are no companies with significant negative impacts that need to be terminated. However, due to the fact that most of the companies are small and medium-sized enterprises, factors such as operational performance meant minimal investment in environmental management policies and minimal performance in areas like sustainable work practices. As such, Chailease Holdings plans to share corporate resources in the future to help enhance the ESG awareness of its partners and improve their related performance.

 

Sustainable Procurement Principles

Items Evaluated

In accordance with the green procurement policy promoted by the Environmental Protection Agency (the products with green labels and energy-saving labels, the certification fees for environmental and energy management systems) and with reference to the spirit of ISO 20400 sustainable procurement guidelines, the concept of sustainability management is incorporated into the procurement policy and procurement practices, requiring partner companies to participate in following green procurement guidelines and designing or producing products that meet green specifications in order to fulfill their corporate responsibilities and expand their influence. We select 100% of local manufacturers as our partners for all procurement cases.

In the “Supplier's Commitment to Human Rights and Environmental Sustainability”, suppliers are explicitly required to evaluate the environmental and social impacts of their procurement practices on the regions from which they supply, and to use relevant materials or services in a manner that protects the natural environment and safeguards the interests of local residents.

Use or procure energy-saving equipment and implement energy-saving measures as far as possible, and give priority to the use of recycled and reused alternative materials in the production of products or the provision of services in compliance with product quality requirements, in order to reduce the negative impact on the environment and society, and to avoid the use of substances that are harmful to the environment and local residents.

Reduce the emission of pollutants, toxic substances and waste, and properly dispose of waste in accordance with relevant laws and regulations to reduce the impact and harm to the environment.

In the supplier selection and management regulations, the raw material procurement policy encourages local procurement, procurement of energy-saving labeled products, and the adoption of friendly processes or the use of environmentally friendly materials and equipment.
