Risk Factor Key Risk Management Measures Decarbonization Implementation Risk To advance global leadership in sustainability, GC has announced its net zero goal, with the medium-term target of reducing 20% emissions by 2030 and achieving Net Zero emissions by 2050. As such, the risks that must be managed in order to achieve these targets include the challenges of carrying out projects under GC’s three decarbonization pathways: efficiency-driven, portfoliodriven, and compensation-driven; as well as the government’s regulatory policies and efforts to align business operations to international climate regulations on matters such as alternative energy, renewable energy, third-party access, and economic tools. In general, GC monitors and analyzes climate scenarios and incorporates them into the formulation of strategies and business plans. Efficiency-Driven Establish performance indicators on greenhouse gas emissions and energy efficiency and incorporate them into the corporate KPIs, as well as monitor and track progress on a monthly basis. Engage internal and external experts to analyze and report the energy consumption of various plants in depth, promote energy efficiency improvement in plants through the ISO 50001 CPI process and operational excellence frameworks, and organize workshops to develop additional quick-win initiatives for GHG reduction. Establish plans and drive renewable energy procurement, monitor trends in clean energy technologies, and analyze their feasibility and suitability for practical applications. Portfolio-Driven Formulate investment portfolio adjustment strategies and project execution plans, and conduct a thorough analysis of policies and trends in low-carbon business development to seek investment opportunities. Study the feasibility of reducing the proportion of businesses with high carbon emissions. Create added value for GC’s existing products by leveraging the benefits derived from the reduced carbon footprint in accordance with the decarbonization pathway. Collaborate with the government and civil society to provide supplementary information for adjusting policies in alignment with the industries in Thailand’s context and driving the development of Thailand’s infrastructure and ecosystem. Compensation-Driven Study and expedite the readiness of carbon capture business development, monitor the development of a supportive ecosystem, clearly define roles in collaborating with associations/networks to advocate for policies, laws, and supporting guidelines, and formulate a roadmap in alignment with GC Group’s action plans so as to ensure the successful development of projects within appropriate timeframes and costs. Seek more efficient and cost-effective carbon capture technologies to apply within GC’s plants. Coordinate with the government to develop reforestation projects at a reasonable cost to earn carbon credits. 93 PTT GLOBAL CHEMICAL PUBLIC COMPANY LIMITED Form 56-1 One Report 2023
