Climate Commitments and Reduction Targets:
Siam Cement is committed to ambitious climate action, aiming for Net Zero greenhouse gas emissions by 2050. This long-term target is supported by several near-term commitments:
- Scope 1 and 2 Emissions: The company has a target to reduce net GHG emissions across Scope 1 and 2 by at least 20% by 2030, using 2020 as the baseline year. Some reports indicate a more ambitious target of a 25% reduction in absolute Scope 1 and 2 GHG emissions by 2030 compared to the 2020 baseline. These targets are recognised as being consistent with reductions required to keep warming to 1.5°C or Well-below 2°C.
- Scope 3 Emissions: Siam Cement has set a target to decrease GHG Scope 3 emissions from the use of sold fossil fuels by at least 25% by 2031, compared to the 2021 baseline.
The company's carbon intensity, measured as specific CO2 emissions per tonne of cement, has shown a declining trend, with gross CO2 emissions decreasing from approximately 669,000 kg CO2e per tonne in 2018 to about 570,000 kg CO2e per tonne in 2024.
