Internal Carbon Pricing

GGC has established an Internal Carbon Price (ICP) as a mechanism to reflect the cost of greenhouse gas emissions, support decision-making in operations and investments, and drive the implementation of GGC’s Decarbonization Roadmap.

The Internal Carbon Price considers two key factors: internal and external inputs. Internal factors include GGC’s carbon reduction plans and greenhouse gas inventory data. External factors include regulatory trends, policies, and carbon market information to assess potential financial impacts. In addition, the framework incorporates sustainability reporting and rating standards such as the Task Force on Climate-Related Financial Disclosures (TCFD), which emphasizes climate-related risk disclosure. This integration enhances transparency and alignment with best practices.

ICP also helps GGC prepare for future regulations, such as Carbon Tax and Emissions Trading Systems currently under consideration in Thailand. Internal Carbon Pricing therefore serves as a proactive tool enabling GGC to anticipate and adapt to new climate-related regulatory requirements.

Application of Internal Carbon Price (ICP) and Business Benefits
Current Business Operations	Business planning support: ICP is used to optimize operational efficiency and reduce greenhouse gas emissions, ensuring that business strategies align with climate targets. Carbon cost assessment: Emissions are translated into financial costs and allocated to ICP budget groups. This budget can be used to support investments in new Low Carbon business opportunities.
New Investments	Project prioritization and investment decision-making: ICP is used to prioritize projects and support investment decisions by evaluating returns after accounting for carbon costs. Supporting sustainable procurement: ICP guides investments in Low Carbon technologies and sustainable finance as part of GGC’s sustainable procurement practices, with the aim of reducing Scope 2 and Scope 3 emissions across the entire value chain.
