The Clean Environment Leaders Summit (CELS) is one of the three pillar events of the CleanEnviro Summit Singapore. The Summit gathers the world's top environment leaders from the public and private sectors, international organisations and think-tanks, to discuss global environment issues, share knowledge, and shape thought leadership and policies on developing sustainable environmental management solutions. At the CELS 2012, expect more than 300 leaders to come together for a meaningful discourse on environmental issues.

The CELS 2012 will take place on 2 July. It comprises the following key events:
