GC has committed to rely on the efficient consumption of energy, in order to increase energy efficiency and maximize benefits by reducing energy loss in every process. GC also regularly checks and maintains the equipment in the production process, as well as raises awareness among its employees in energy saving and contribute to SDGs.

GC has continuously implemented energy conservation projects in order to improve energy efficiency, develop renewable energy, reduce greenhouse gas emissions from production process, as well as raise awareness among its employees to reduce energy consumption within the offices. As a result, the efficient implementation of energy management in 2025 included.

Overall Energy Conservation Projects in 2025 GRI 302-4 (2016)

GC has conducted energy conservation projects, focusing on enhancing energy efficiency and optimization. Additionally, GC mandates that all factories obtain certification for their energy management systems in accordance with ISO 50001 by the Management System. Energy audits are regularly carried out, utilizing energy data to analyze progress and identify opportunities for reducing energy consumption. Substantial investments have been made in innovation and R&D to initiate energy reduction and conservation programs. Furthermore, GC provides training sessions to enhance employee awareness of reducing energy consumption in both production processes and office environments.

GC conducts training to raise employee awareness on reducing energy consumption in both production processes and office operations through various programs. These include the Aspen Exchanger Design and Rating (EDR) course, which provides process engineers with the knowledge and skills needed to properly design and analyze shell-and-tube heat exchangers for optimal efficiency and reduced energy use in production processes. The Company also runs energy management training programs to enhance understanding of ISO 50001-based energy management within the organization for staff responsible for environmental matters, enabling them to effectively review energy management performance and identify opportunities for further improvement.
