Since 2010, Seoul has hosted annual international forums on air quality and biennial mayoral forums on climate change to foster discussions on urban air quality improvement and climate actions. Based on the past years’ experience and recognizing the interconnectedness of air pollution and climate issues, Seoul has merged these forums into a single event called the “Seoul International Forum on Climate and Environment” to streamline efforts towards sustainable development and achieving carbon neutrality. As an official partner, ICLEI East Asia leverages it global network to support the organization of the Forum and supports Seoul Metropolitan Government to spotlight innovative solutions and fosters a collaborative environment for stakeholders to drive meaningful change in urban sustainability.
