ICLEI worked with partners to organize the Low-Carbon City 2.0 Professional Series Workshops and The International Conference on Mitigation Strategies for Green Transformation in Cities. International experts from Korea, Japan, Singapore, and Malaysia were invited to give a series of trainings on decarbonizing actions, urban energy efficiency improvement and low-carbon transformation featuring case studies in East Asia cities and the world. The in-depth discussions between local officers and international experts enhanced the sense of responsibility of carbon reduction in various departments, and promoted the role of local governments in changing from “regulation” to the supporting multi-stakeholders in the new climate and low carbon regime.
