GC's Global Sustainability Awards Built on Bold Innovation
Chemical company GC has earned seven consecutive years of top global rankings for sustainability by embedding ESG principles across operations, from developing sustainable aviation fuel to reducing emissions by over 400,000 tons of CO2 sinc
While many see sustainability as distant, GC has made it core to every business process—from product development to resource management to environmental innovation. The chemical company drives its operations through ESG principles and circular economy practices, turning ideas into real results: recycling used plastics, developing eco-friendly materials, and deploying carbon-reduction technology.
All these initiatives reflect the same philosophy: "differentiation that creates sustainable value." This commitment has earned GC continuous global recognition through multiple ESG awards and indices.
GC's sustainability efforts have won consistent worldwide recognition. The company ranks first globally in its chemical products segment according to S&P Global CSA assessments for seven consecutive years and has been selected for the S&P Global Sustainability Yearbook for 13 straight years among over 9,200 companies worldwide.
GC also appears in both the Dow Jones Best-in-Class World Index and Emerging Markets Index. It achieved the highest "A" rating for Water Security from CDP for six consecutive years, demonstrating effective resource and environmental management at an international level. In Thailand, GC earned the highest SET ESG Rating of "AAA" for three years running and has been on the sustainable stocks list for 11 consecutive years.
Though each assessment framework differs, a consistent theme emerges: GC applies ESG principles to deliver long-term results for business, people, society, and the environment.
What sets GC apart is its ability to convert ideas into results through innovation that solves problems and creates value across business, society, and the environment simultaneously.
A major example is GC's development of Sustainable Aviation Fuel (SAF) from used cooking oil—the first such production in Thailand. By leveraging existing infrastructure and expertise, the company produces sustainable jet fuel without building new plants, while also advancing toward biochemicals and bioplastics. This reduces greenhouse gas emissions and adds value to waste resources.
GC is advancing toward Net Zero by 2050 through improved production efficiency, optimized energy use, and investment in low-carbon technology. Between 2021 and 2025, the company cut cumulative greenhouse gas emissions by over 400,000 tons of carbon dioxide equivalent.
In water management, GC deployed Wastewater Reverse Osmosis (WWRO) technology to recycle treated wastewater, reducing freshwater consumption by up to 1.8 million cubic meters annually.
The GC YOUTurn programme exemplifies circular economy in action, involving partnerships with over 140 organizations across Thailand. The initiative now operates more than 400 used plastics collection points.
