Greenhouse Gas Management Policies and Initiatives

Greenhouse Gas Management

TCC values environmental sustainability and adopts a dual approach of mitigation and adaptation to address the impacts of climate change. In alignment with the government's 2050 net-zero emission target, we have developed our greenhouse gas management and carbon reduction strategies, establishing the following policies:
  1. Continuously implement energy-saving measures to reduce energy consumption.
  2. Enhance energy resource utilization and power generation efficiency to lower internal energy use and carbon emissions.
  3. Maintain and upgrade equipment as needed, improve processes, and promote low-carbon transformation.
  4. Develop low-carbon technologies and businesses, progressively moving towards net-zero emissions.
  5. Comply with environmental regulations, customer requirements, and relevant policies.
 

Implementation Measures

  • Establish a greenhouse gas management mechanism, promote inventory and verification processes, and build a comprehensive database to facilitate the formulation and validation of reduction plans and targets.
  • Continue implementing energy-saving and carbon reduction measures, including equipment upgrades, process improvements, and power-saving initiatives to decrease energy consumption.
  • Actively expand renewable energy-related businesses, covering investment and development, engineering contracting, operations and maintenance, green power sales, as well as emerging power trading models such as energy storage and ancillary services.
  • Assess the feasibility of adopting Carbon Capture, Utilization, and Storage (CCUS) and low-carbon/negative-emission technologies, including hydrogen co-firing in gas-fired power plants, to accelerate the transition to a low-carbon future.

Targets and Progress

Status of Target Achievement for 2025

Using 2014 as the baseline year, the Guan Tian Plant aims to reduce carbon emissions per NT$1 million revenue (individual entity) by:
  • 35% by 2025
CHECK 2025: The Guan Tian Plant aims to reduce carbon emissions per NT$1 million revenue (individual entity) by 71%

The plant's average energy-saving rate from 2025 to 2028 is over 1.5%:
CHECK2025: Achieved  annual energy-saving rate of 3.97%.

A fuel substitution rate of ≥30% has been set, using scrap tires and solid recovered fuel (SRF) to reduce coal consumption:
CHECK2025: Fuel substitution rate of 31.77%, reducing 53,150 metric tons of coal.

Short-term target

1. A fuel substitution rate of ≥30% has been set, using scrap tires, solid recovered fuel (SRF) and solid biomass fuel to reduce coal consumption
2. The plant's average energy-saving rate from 2025 to 2028 is over 1.5%
3.By increasing the use of solid biomass fuel, the Guantian Plant aims to reduce carbon emissions by 1% in 2026 compared to 2025
 

Medium- and long-term target

1. Using 2021 as the baseline year, the Guan Tian Plant aims to reduce carbon emissions by 42％ by 2030
2. Maintaining an average energy-saving rate of 1.5% from 2025 to 2030

Remark
1. Data for both 2024 and 2025 have been verified by a third party. The 2024 organizational boundary covers TCC Head Office and Guantian Plant, while the 2025 boundary expands to include subsidiaries in the consolidated financial statements in addition to TCC Head Office and Guantian Plant. National electricity carbon emission factors were 0.474 kg CO₂e/kWh for 2024, and 0.467 kg CO₂e/kWh for 2025.

2. The Company’s greenhouse gas inventory is conducted in accordance with ISO 14064-1. The types of gases included in Scope 1 and Scope 2 calculations include: carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF₆), and nitrogen trifluoride (NF₃); selected categories under Scope 3 are also voluntarily disclosed.
