Adaption to climate change
Although the operations of the TWSE and its subsidiaries do not constitute a major impact on the environment, the company does its part to curb energy consumption and carbon emissions. This is in line with the global trend of eliminating climate change impacts and the TWSE's own role as a supervisory authority of the market. By outlining the disclosure process of climate-related information for listed companies, the TWSE provides a solid foundation for the construction of an ecosystem for net zero transformation.

Energy consumption and greenhouse gas emissions
The TWSE and its subsidiaries mainly provide financial and IT services, and the majority of its energy consumption is by its offices (including public facilities) and data centers, as well as gasoline consumption by company cars and diesel fuel consumption by backup power generators.
For the first time, the TWSE conducted greenhouse gas inventory for all subsidiary companies of the group in 2022. Some reported data has increased compared to previous years due to complete inventory of emission sources. The scope of inventory includes Category 1's direct greenhouse gas emissions (refrigerants, gasoline, diesel, etc.), Category 2's indirect greenhouse gas emissions from imported energy (electricity), Category 3's indirect greenhouse gas emissions generated by transportation (business travel emissions), and Category 4's total indirect greenhouse gas emissions caused by organizations' use of products (capital goods, fuel, and energy-related activities). Among them, the greenhouse gas emissions of Categories 1 and 2 have been listed as confirmed indicators in this report, and a verification statement has been obtained from the accountant in accordance with ISAE 3000.

Carbon reduction targets
In addition to reporting on Categories 1 and 2 greenhouse gas emissions, the TWSE, for the first time in the 2022 Sustainability Report, conducted an inventory of Categories 3 and 4. Using the 2022 inventory data as the base year, the TWSE establishes short, medium, and long-term goals as follows:
Renewable energy and environmental measures
To support the government's green energy transition policy with tangible actions, the TWSE installed 11.34 kW solar panels on the roof of its First Data Center which generated 1,056 kWh in 2022, an equivalent of carbon reduction of 537.5 kg CO₂e。
The TWSE exerts great effort in energy conservation. It uses LED lights, a two-way lighting system (smart energy conservation); the central air-conditioning water-cooling system at our office makes ice at night and uses the ice in the day. Furthermore, the TWSE continues to utilize energy efficient information systems to keep up with the increased trading due to the launch of continuous trading and intraday odd lot trading. The TWSE is dedicated to ensuring energy efficiency and resource efficiency while enhancing service quality and stability.
In 2022, the TWSE's Power Usage Effectiveness ("PUE"1 ) was 1.64, and the company aims to continue lowering its PUE ratio by conserving energy through the HVAC system, improving the operation environment of the server rooms, and conducting regular maintenance checks to reduce energy consumption, thereby achieving the goal of reducing carbon emissions.
The TWSE's largest subsidiary, the TDCC, introduced the ISO 50001 Energy Management System and acquired external certification to monitor energy hotspots as a basis for continuous improvement.

Paperless office and policy
The TWSE and its subsidiaries actively promote methods for a paperless office to meet carbon reduction requirements; the actions of the TWSE are as follows:
The TWSE and its subsidiaries, in addition to establishing internal online filing, also actively promote electronic filing of relevant procedures on the part of listed companies. This not only improves the effectiveness of information integration and transmission, but also influences others in fulfilling the carbon reduction requirements.
