Control and Reduction of Volatile Organic Compounds (VOCs) GC controls and reduces Volat i le Organic Compounds (VOCs) at the sources, beginning with the annual inventory of VOCs emission. In case TVOCs exceed GC’s internal control limit, that more stringent than the governmental limit, the Company immediately repairs equipment to reduce potential impacts and implements a maintenance program of equipment to minimize VOCs released to the atmosphere. GC has also installed a Vapor Recovery Units (VRU) and Vapor Return Lines to transport the vapors of hydrocarbons which might potentially be released into the atmosphere, and bring them back into the storage tanks for proper usage or management. To further control and reduce VOCs, GC in collaboration with five petrochemical industrial estates and one terminal industrial estate in Map Ta Phut have initiated a pilot project to manage Benzene vapors and 1, 3-Butadiene by introducing Code of Practices (COP), to help solve the release of the chemicals from industrial plants. GC has also applied innovation and technology to the proactive air quality monitoring and control both inside and around GC’s sites during day-to-day business conductivity and during turnarounds, while also implementing vapour control measures by requiring the measurement of vapour prior to equipment operation to ensure that it does not exceed our internal control limit which is stricter than the limit stipulated by the applicable laws, including installed scrubbers to extract and draw vapour back to the production process and not being released to the atmosphere, e.g. installing blower to extract and draw vapour into the activated carbon system, to ensure that GC’s activities have no impact on the environment and the areas in the vicinity of its sites. 3.3) Leadership in Sustainable Environmental Management Operating on the basis of sustainability, GC actively prioritizes and drives solutions as well as mitigation of impacts of climate change and water management issues, which have grown increasingly severe, so as to achieve the goal of the Paris Agreement and the United Nations’ Sustainable Development Goals (SDGs). Climate Strategy GC strives to become a world-class leader in the management of greenhouse gas (GHG) emissions as well as support Thailand’s GHG targets and the direction of the Paris Agreement under the 26th session of the Conference of the Parties (COP26) of the UN Framework Convention on Climate Change. It has also taken part in affirming its commitment to GHG reduction to meet the United Nations’ SDG 13: Climate Action. GC has set a goal to reduce the emission of greenhouse gas to zero (Net-Zero Emission) under both scope 1 and 2 and reduce the emission of greenhouse gas under scope 3 by 50% within 2050 by applying the Circular Economy principle combining with various methods of decarbonization. With regards to its climate policy and continuous climate actions, GC received the highest rating of A in Leadership Level under the assessment framework of the Carbon Disclosure Project (CDP), one of the world’s most reliable sustainability assessment institutions – a testament to GC’s commitment to climate change management. Water Management GC strives to contribute to the achievement of the United Nations’ SDG 6: Clean Water and Sanitation and focuses on sustainable water management and water crises, both internally and externally, through its One Water Strategy and governance under the Leadership in Sustainable Environmental Management United Nations’ Sustainable Development Goals (SDGs) Paris Agreement Climate Strategy Water Management Product Stewardship 178 PTT GLOBAL CHEMICAL PUBLIC COMPANY LIMITED Form 56-1 One Report 2021
