The Sustainability Expo 2025 (SX2025), ASEAN’s largest sustainability event, returned for its sixth edition under the theme ‘Sufficiency for Sustainability.’ Inspired by the First Royal Command of His Majesty King Maha Vajiralongkorn Phra Vajiraklaochaoyuhua and the Sufficiency Economy Philosophy of His Majesty King Bhumibol Adulyadej The Great, the expo underscores the balance between economic growth, social progress, and environmental stewardship.
Leading the movement, PTT Group reaffirmed its commitment to achieving Net Zero Emissions by 2050 through its C3 strategy Climate Resilient Business, Carbon-Conscious Assets, and Coalition, Co-Creation, and Collective Efforts for All while championing inclusive growth, renewable energy, and community empowerment. Held from 26 September to 5 October 2025, SX2025 gathered more than 750 global experts and 270 organisations from Thailand and beyond to exchange knowledge, showcase innovation, and co-create pathways toward a balanced, sustainable future.
