To make effective management of energy use and reach the goal of energy conservation and carbon reduction, Chunghwa Post has introduced ISO 50001 Energy Management System in 19 bases including Chunghwa Post Jinshan Building in 2022. In addition, the Company also attaches great importance to environmental protection and compliance with relevant regulations and has thoroughly reviewed the safety and health plan proposed by manufacturers to ensure the manufacturers conduct autonomous inspection as prescribed. Meanwhile, the frequency of random inspections is increased and the fines for manufacturers’ violations are also increased. There were no violations of environmental regulations in 2022.

To implement net zero emission and environmental sustainability, Chunghwa Post has actively constructed green building for energy conservation and carbon reduction to make its contribution to the earth, aiming at achieving environmental sustainability. So far, a lot of results have been achieved in the buildings of our post offices. As of the end of 2022, the cumulative number of Green Mark has reached 19, 10 of which met the CO2 reduction targets, while the number of Green Building Candidate Certificates was 32, 18 of which met the CO2 reduction targets.
In 2022, one Green Building Candidate Certificate (Linkou Post Office, Chungcheng Branch)and two Green Marks (Taichung Lingdong Post Office, Miaoli Toufen Post Office) were approved.It is hoped that every new building of Chunghwa Post will meet the daily energy-saving and waterresource indicators in the future.

The Company’s energy consumption statistics cover 21 operating locations, including the Head Office buildings (Jinshan and Aiguo Buildings), Taipei Post Office, Banqiao Post Office, Sanchong Post Office, Taipei Mail Processing Center, Taoyuan Post Office, Taichung Post Office, Tainan Post Office, Kaohsiung Post Office, Keelung Post Office, Hsinchu Post Office, Changhua Post Office, Chiayi Post Office, Yilan Post Office, Miaoli Post Office, Nantou Post Office, Yunlin Post Office, Pingtung Post Office, Hualien Post Office, Taitung Post Office and Penghu Post Office.

To improve the efficiency of postal delivery, the Company had continued to increase the number of vehicles in recent years. The number of mails sent and received in 2021 increased slightly, yet the e-scooters were additionally purchased at the end of 2020, so the use of fuel scooters in 2021 decreased, leading to the decrease of energy use compared with 2020. In 2022, the use of postal vehicles with more than four wheels increased, leading to a slight increase in energy consumption in 2022 compared with 2021.

Starting from 2015, Chunghwa Post has successively installed solar PV power generation systems on the roofs of the buildings of its post offices to increase the use of renewable energy. In 2022, 1,052.21 kW of rooftop solar PV equipment was installed, with an annual power generation of about 1,051,400 kWh, with an annual carbon reduction of 1,520 tons. In 2022, a 3kw wind power generation facility was installed on the roof of the Postal Logistics Center. In the future, we will gradually increase the proportion of renewable energy use by installing solar power generation systems on the roofs of the building of every post office. Chunghwa Post Installed solar PV power generation system with the total capacity of 3,501 kWh from 2015 to 2022, producing 3.92 million kWh annually, reducing carbon emissions by approximately 2,076 tonnes.

To effectively manage climate change-related risks and GHG emissions, since 2019, Chunghwa Post has introduced ISO 14064-1 GHG Inventory and passed external verification in the Head Office buildings (Jinshan and Aiguo Buildings), Taipei Post Office, Banqiao Post Office, Sanchong Post Office, Taipei Mail Processing Center, Taoyuan Post Office, Taichung Post Office, Tainan Post Office, Kaohsiung Post Office, Keelung Post Office, Hsinchu Post Office, Changhua Post Office, and Chiayi Post Office.
