With a large construction industry, buildings in Thailand pose a number of challenges including project implementation and scalability under new national building standards, reliance on air conditioning, and inadequate at source waste management infrastructure. GGGI Thailand’s program focuses on “physical green infrastructure” for waste management, green building, and green industry sectors. GGGI’s climate action will mobilize green investments through the formulation of green growth policies, strengthening national mechanisms, institutional capacity building and climate finance mechanisms, including carbon pricing. In essence, Thailand program is a practical Green Cities program. Circularity, resource efficiency, methane mitigation and innovation enhancements are the key drivers.
