ICLEI–Local Governments for Sustainability is the world's leading network of over 1,500 cities, towns, and regions committed to building a sustainable future. ICLEI Southeast Asia Secretariat (ICLEI SEAS), based in Manila, Philippines, currently serves ICLEI Members in Indonesia, Malaysia, the Philippines, and Thailand.

ICLEI SEAS assists Member local governments by designing, promoting, and drawing external support for programs and campaigns that develop local resiliency and sustainability. We enter partnerships in order to build a regional and national policy environment that strengthens local governments and promotes local sustainability. We bring local government leaders together with experts, industry leaders, academics, and national international agencies for exchanges on potential solutions to a wide range of urban challenges.

ICLEI’s Mission is to build and serve a worldwide movement of local governments to achieve tangible improvements in global sustainability, with special focus on environmental conditions through cumulative local actions.
