Chunghwa Post actively promotes GHG inventory. However, the number of our operating locations is higher than that of other peers in the financial and insurance sectors, with a total of 1,297 post offices at all levels across Taiwan, including the Head Office and the Taipei Mail Processing Center, resulting in a broad scope for inventory operations. To strengthen the carbon management mechanism at the organizational level and facilitate the planning and promotion of the subsequent carbon reduction action plans and phased goals, Chunghwa Post has gradually introduced GHG inventory operations since 2019, and continued to implement GHG management. To align with international trends and cooperate with national policy and objective to step toward net-zero emissions by 2050, the GHG inventory operations at all our operating locations initiated in 2024. The inventory scope included the Jinshan and Aiguo Building of the Head Office, Taipei Mail Processing Center, and all post office branches (some branches include administrative units), and was verified by a third party. In 2024, the GHG emissions of all the operating locations in Taiwan reached 78,400.5749 tCO2e, and the GHG emission intensity was 0.30 tCO2e/NT$ million. The results of the carbon inventory showed that the carbon dioxide generated at Chunghwa Post mainly comes from the gasoline and diesel used in the transportation and the purchased electricity of all the operating locations.

To effectively improve the energy efficiency, Chunghwa Post not only conducts GHG inventory but also imports ISO 50001:2018 Energy Management System in stages. Each office then evaluates its self-owned building. The ones in high energy consuming areas, with equipment that had not been repaired or replaced for long and were in urgent need of energy conservation improvement were prioritized as a counseled branch for establishment. In 2023, a total of 37 locations established the energy management systems and passed verification as well as obtained certificates. In 2024, guidance for the continuous improvement of the energy management system originally installed by Chunghwa Post and the post offices was conducted, and it was also expanded to include 104 special branches and Class A post offices in the operation, completed the third-party system verification and obtained the certification on January 30, 2025.

For the 21 operating locations with relatively high electricity consumption, the main job is to implement the replacement of lighting equipment and air-conditioning systems in 2024. The total estimated energy saved reached 1,473,974 kWh/year, equivalent to 5,306.31 GJ. The GHG equivalent reduction is approximately 698,663.68 kgCO2e (based on the 2024 electricity carbon emission coefficient announced by the Energy Bureau of the Ministry of Economic Affairs).

At the same time, Chunghwa Post is also devoted to various green innovative services, which not only enhance our customers’awareness of energy conservation and carbon reduction, but also reduce operating costs and improve the competitiveness in sustainability issues. We can further practice green living in daily lives, actively respond to various indicators of green office, and jointly conserve energy and resources by implementing paperless and green procurement measures, creating an eco-friendly working space and motivating our employees to work in a green office As of 2024, a total of 230 post offices have responded to Ministry of Environment’s Net-Zero Green Life- Responding to Green Office Campaign.

In response to the green energy policy, Chunghwa Post has implemented a policy to promote the use of electric scooters and e-vans since 2017. The number of vehicles purchased and the quotas allocated to each unit depend on factors such as the number of delivery sections of each post office, the age of existing vehicles, mileage, and the annual budgets. However, as the current transport capacity of electric vehicles (EVs) cannot fully replace that of traditional fuel-powered ones yet, a full-scale replacement has not been carried out. In the future, we will continue to improve the overall energy efficiency through continuous improvement of the transportation operation process. Meanwhile, attention to the development of vehicle-related technology is also paid for a timely replacement with new ones to meet the postal business demands while taking into account energy conservation and carbon reduction.

To improve the efficiency of postal delivery, the number of vehicles used has continued to increase in recent years. In 2024, with the use of electric vehicles and the continuous promotion of carbon reduction measures in transport, energy consumption decreased by 11.80% compared with 2023.

To implement the ESG energy conservation and carbon reduction policy and fully grasp the electricity consumption condition, the Robotic Process Automation (RPA) technology was introduced in 2022 to automatically capture the monthly electricity consumption data of all units and post offices of Chunghwa Post and analyze the monthly power consumption with a visual and interactive dashboard. In addition, the electricity conservation rate is also calculated for the comparison of that during the same period in the previous year, which allows the unit in charge to make instant control of the electricity consumption of the whole company. This not only effectively reduces the entire time of data collection and inventory of electricity accounts by manpower but also improves the efficiency of electricity management as a whole.
Over the past two years (2023 to 2024), the Company has compiled electricity usage data to analyze its overall electricity consumption. Compared with the previous year, the Company achieved a power saving rate of 2.51%, demonstrating a significant energy-saving effect.

From 2023, to take inventory of and grasp the carbon emission situations, Chunghwa Post installed a data dashboard to convert electricity consumption into carbon emissions. The electricity consumption data collected is multiplied by the electricity carbon emission factor announced annually to convert data into carbon emissions, allowing the unit in charge to grasp the instant carbon emissions from electricity consumption in each office and branch in every month and year.
