Jojo Mehta co-founded Stop Ecocide in 2017, alongside barrister and legal pioneer the late Polly Higgins, to support the establishment of ecocide as a crime at the International Criminal Court. As CEO and key spokesperson, she has overseen the remarkable growth of the movement while coordinating between legal developments, diplomatic traction and public narrative. She is Chair of the charitable Stop Ecocide Foundation and convener of the Independent Expert Panel for the Legal Definition of Ecocide chaired by Philippe Sands QC and Dior Fall Sow. The resulting definition, launched in June 2021, has catalyzed legislative developments, recommendations and resolutions at national, regional and international levels.
