(2) The Siam Cement Public Company Limited (SCG)

The Siam Cement Public Company Limited, commonly known as SCG, operates within the same
industrial sector as PTT, an extractive industry that sources raw materials from the earth, such

as oil, coal, and various minerals. As a result, its production processes often involve drilling,
pumping, and blasting soil or rock for mining. In this context, SCG has acknowledged the critical
responsibility it bears in addressing global warming, climate change, environmental
degradation, inefficient use of energy and resources, and broader concerns related to quality
of life and workplace safety. These challenges must be tackled in parallel with the company’s
efforts to grow its business amid evolving environmental, social, and technological conditions.
To this end, SCG has developed a sustainability strategy centered on three key dimensions:
circular economy, climate resilience, and transportation safety (see Table 9.5).
