The 21st century is defined by an urgent and interconnected set of global challenges: climate change, environmental degradation, resource depletion, and escalating energy demands. The scientific consensus is clear—transitioning from a fossil-fuel-based economy to a sustainable, low-carbon future is no longer an option but a necessity for the well-being of our planet and future generations. We are pleased to announce the 2026 9th International Conference on Green Energy and Environment Engineering (CGEEE 2026) to be held in Seoul, South Korea during July 17-19, 2026. CGEEE 2026 will provide a forum for researchers and practitioners in the field to share ideas, designs, and experiments. Participation from academia, industry and government is welcome.
CGEEE has been successfully held in Hokkaido, Kitahiroshima, Sapporo, Okinawa, Japan, Jeju as international event for scholars throughout the world. The conference will continuously encourage innovative academics and industrial experts in the field of Green Energy And Environment Engineering to a common forum.
