[DigitalToday reporter Choi Jae-won (최재원)] Taiwan Railway Corp has for the first time surveyed companywide greenhouse gas emissions and will seek a 3 percent cut by 2028 from a 2025 baseline of 428,400 tonnes of CO2e.

IT Home, a Taiwan media outlet, reported on Oct. 6 local time that Taiwan Railway Corp surveyed emissions at 613 sites including stations, depots, maintenance facilities, office space and ancillary facilities. It previously examined 32 major stations and has now for the first time identified emissions across the company.

The biggest source of emissions was train operations, accounting for 75.1 percent of the total, or about 321,600 tonnes of CO2e. Station operations accounted for 15.6 percent, or about 67,000 tonnes. Taiwan Railway Corp plans to use 2025 as the base year and cut total emissions 3 percent, or about 13,000 tonnes of CO2e, by 2028. This is a total reduction target over three years, not 3 percent per year.

Taiwan Railway Corp is pushing 11 reduction projects across six areas including train operations, station operations, track and rolling-stock maintenance, office space and restaurants. Key measures include introducing new energy-efficient trains, power-saving operations, expanding LED lighting, replacing air conditioning and chilled-water facilities, and shifting shared vehicles to low-carbon options. New power-saving trains have been delivered in stages since this year.

It is also strengthening data-based energy management. It is building SOPHIA, a cloud platform that integrates operational and facility information, and is also pursuing 73 solar projects using stations and depots. An official announcement also presented regenerative braking, smart maintenance and digital transformation as key tools for emissions cuts.

An expansion of mobile ticketing has also had an effect. The share of users rose to 20.38 percent in 2025 from 5.94 percent in 2019, and a cumulative 55.36 million tickets were issued, cutting about 341 tonnes of CO2e and saving more than 55.36 million Taiwan dollars in printing costs. Taiwan Railway Corp plans to refine carbon data by mode of transport and use it for energy management and as a basis for a transition to net zero by 2050.
