The postal, saving and life insurance business processes of Chunghwa Post all require documents and receipts. To reduce the consumption of paper, digital services are provided to replace physical paper consumption. Our customers are also encouraged to reuse postal convenience boxes while enjoying postage discounts. In 2023, 4,034,859 convenience boxes were used for the first time, and 601,518 were recycled, with the reuse rate of 12.97%.
Note: Reuse rate (%) = Number of boxes reused/ (number of boxes used for the first time + the number of reused boxes).

To actively respond to the green building promotion policy, lowcarbon design is introduced for the renovation of old buildings. It is hoped that our new buildings will meet the daily energy conservation and water resources indicators in the future. In 2023, one Green Building Label was obtained (Postal Logistic Center), and the number of approved Green Building Candidate Certificates was three (Taitung Fengtian Post Office, Yulin Mailiao Post Office, and Tainan Madou Post Office). From 2003 to 2023, the cumulative number of Green Building Label was 21, among which 12 met the Carbon Dioxide Reduction Index; the cumulative number of Green Building Candidate Certificate was 36, among which 18 met the Carbon Dioxide Reduction Index.

The postal logistics park will make full use of renewable energy such as wind and solar energy and combine smart energy management and smart sensing to plan to obtain the Green Mark and Smart Building Label. In addition, the functions and life of the buildings in the park are improved based on the Building Information Modeling (BIM). Incorporated with the design concept of humanization and sustainability, multi-functional intelligence management systems with the functions of safety monitoring, traffic guidance, park management, personnel control, intelligent lighting and intelligent conference rooms are planned to achieve a smart green building with environmental protection, energy saving and humanity, and the energy saving potential of the buildings is estimated to be more than 30%.
The first landmark building in the park- the Postal Logistics Center was completed at the end of 2022 and was officially commenced in 2023. The center is compliant with smart building and green building regulations in terms of architectural design, and 30 sets of 3kw wind power generation facilities have been installed on the roof, that can be used to assist and support public facilities and power consumptions in the basement floor. It is planned to install 374 solar power modules (size:L1650 * W992 * H40) on the roofs of the North Taiwan Mail Operating Center (under construction), with a total installed capacity of 117.81KW. It is estimated to generate 138,000 kWh of electricity annually. Charging equipment for electronic vehicles has also been installed. With the combination of information technology and the concept of green energy, coupled with the comprehensive use of smart sensor network control and high-efficiency electromechanical integration technology, the quality and
function of the building can be effectively improved. At the same time, we cooperate with Taoyuan City Government’s sustainable environment policies and inform the tenants and contractors of relevant air quality control measures and prohibit vehicles that have not yet passed exhaust emission tests from entering the park facilities to create a safer, more comfortable, convenient, energy-saving, and highquality working environment.

Water use at Chunghwa Post is mainly for daily use in the offices, and the source is all from the tap water, which would not cause a major impact on the water intake. In 21 operating locations including Jingshan Building, due to the easing of the epidemic, various meetings, activities, and training courses were gradually resumed in 2023, leading to the increase of water consumption. The total water consumption in 2023 totaled 215,016 million liters, a 6% increase compared with 2022, with the water intensity of 0.94 million liters/NT$ million dollars.
