Note:

  1. Coverage: 100% of production volume

  2. The data in this table was inventoried according to the Ministry of Environment's inventory guidelines (ARS), and therefore, there is a slight discrepancy compared to the ISO 14064 database (AR6).

  3. The 2024 disclosure scope covers the emission data of cement plants in Taiwan, Mainland China, and CIMPOR & OYAK CEMENT.

Internal Carbon Pricing & Carbon Trading Platform

Management Approaches

  • Daily: AI Carbon Reduction Management Platform real-time data, warnings for achievement situation; Monthly: Reports on executives' management meetings; Annually: Tied with performance bonus.

  • In 2021, based on the SBT commitment, the "Alternative Raw (Fuel) Material Indicator Assessment Method" was established, and each plant set carbon reduction assessment indicators according to the actual situation.

  • TCC set an internal carbon price of NT500/ton-CO2e in Taiwan with reference to recommendations from the 5th Carbon Fee Review Committ•ee in 2024, and RMB 105/ton-CO2e in Mainland China based on IEA's World Energy Outlook Report STEPS scenario and local carbon market prices. This pricing aids in assessing the impact on capital investments and operations. CIMPOR and OYAK CEMENT established internal carbon pricing based on forecasts from the European Cement Association(CEMBUREAU), IEA, and BNEF. For their 2025 investment sensitivity analysis, both use a projected 2030 external carbon price of EUR 150 per metric ton CO2e.

  • Internal Carbon Trading: TCC launched an internal carbon trading platform in 2024. By calculating site-specific emission allowances and effectiveness, this platform will strengthen responsibility, foster collaboration, and encourage technological innovation.
