Solar Energy
In 2024, GC expanded our solar energy project through the installation of 1.2 MW Solar Rooftop system at the Aromatics 2 Plant and 0.6 MW Solar Floating system at the InnoPlus Solution Center. GC also collaborated with partners to produce 8 MW equivalent of floating solar pontoons to generate electricity for companies in the Eastern Seaboard Industrial Estate in Rayong province. In this regard, InnoPlus high-density polyethylene (HDPE) pellets are used in the production of SUNTARATM floats, which feature exceptional strength.

Biogas
Global Green Chemicals Public Company Limited (GGC), a subsidiary of GC, signed a contract to purchase biogas from Thai Eastern Biopower Company Limited (TEBP) with a maximum initial volume of 34,000 cubic meters per day to replace the use of fossil fuel in steam boilers and hot oil boilers in GGC2 site, which has contributed to the continuous decline in greenhouse gas emissions from the production process as well as company costs.

Carbon Capture and Storage (CCS) Study in collaboration with PTT Group
GC, in collaboration with the PTT Group, has undertaken a study on a Carbon Capture and Storage (CCS) project in Eastern Thailand to help reduce the country’s greenhouse gas emissions. This initiative, known as the Eastern Thailand Carbon Capture and Storage Hub (CCS Hub), includes the development of a project study report (White Paper), which has been submitted to the government on behalf of the PTT Group. The proposal outlines a national pilot project for the application of carbon capture, utilisation, and storage (CCUS) technologies, with operations expected to commence in 2034. Currently, GC is exploring alternative emerging carbon capture technologies to compare with existing solutions in terms of efficiency and cost. The study also includes an assessment of feasibility and potential for future investment decisions.
Framework for Industry’s Net-Zero Transition
GC, together with the Petrochemical Industry Club of the Federation of Thai Industries (FTIPC), has proposed a decarbonization guideline for Thailand’s petrochemical sector through the “Framework for Industry’s Net-Zero Transition” project, under the Clean Energy Finance & Investment Mobilization (CEFIM) initiative and the Organization for Economic Cooperation and Development (OECD). As part of this effort, GC Carbon Capture and Storage (CCS) project is being advanced and will be assessed and included in the OECD project report. The findings will be submitted to relevant government agencies to support coordination and further implementation.
Nature-Based Solutions
GC has taken action to conserve and restore natural resources in collaboration with government agencies, the private sector, and local communities. It aims to offset one million tonnes of carbon dioxide equivalent (tCO2e) by 2050 through three key approaches: 1) Reforestation projects, including both terrestrial and mangrove forests, 2) Forest conservation initiatives, and 3) The purchase of removal-type carbon credits. In addition, GC is exploring other potential initiatives, such as alternate wetting and drying (AWD) rice cultivation. These efforts not only contribute to climate mitigation but also enhance biodiversity, supporting plant and animal species and entire ecosystems, while generating additional income for local communities through inclusive participation in forest planting, maintenance, and restoration.
As a result of diverse greenhouse gas emissions reduction projects, GC’s cumulative greenhouse gas emissions reduction is as follows:
