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:- Continuously implement energy-saving measures to reduce energy consumption.
- Enhance energy resource utilization and power generation efficiency to lower internal energy use and carbon emissions.
- Maintain and upgrade equipment as needed, improve processes, and promote low-carbon transformation.
- Develop low-carbon technologies and businesses, progressively moving towards net-zero emissions.
- 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
Targets
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
- 50% by 2030
The plant's energy-saving plan targets an annual electricity savings rate of over 1% on average by 2024:
- 2024: Estimated energy-saving rate of 0.73%.
- 2015–2024: Achieved an average annual energy-saving rate of 1.28%.
A fuel substitution rate of ≥30% has been set, using scrap tires and solid recovered fuel (SRF) to reduce coal consumption:
- 2024: Fuel substitution rate of 29.77%, reducing 48,274 metric tons of coal, equivalent to 97,851 metric tons of CO₂e, with an additional 1,133 metric tons of CO₂e reduction benefits.
