About the CAO : Our Roles

Arne Hoel, The World Bank

CAO was established with three complementary roles, which together provide a flexible framework for handling people's complaints, addressing systemic concerns about IFC and MIGA projects, and catalyzing institutional learning.

CAO's Three Roles

Dispute Resolution

CAO's Dispute Resolution function responds to complaints by people affected by the social and environmental impacts of IFC/MIGA projects. Through Dispute Resolution, CAO works with communities and IFC/MIGA client companies to resolve grievances using a flexible problem-solving approach, and improving outcomes on the ground. CAO specialists are trained in alternative dispute resolution, with expertise in conflict assessment and management, mediation, and facilitation. Learn more about CAO's Dispute Resolution role.


Through its Compliance function, CAO oversees investigations of IFC's and MIGA's social and environmental performance, particularly in relation to sensitive projects to ensure compliance with relevant policies, guidelines, procedures, and systems. Learn more about CAO's Compliance role.


CAO Advisor provides independent advice to the President of the World Bank Group and management of IFC and MIGA.  CAO advice focuses on broader social and environmental concerns, policies, procedures, strategic issues, and trends. CAO's focus is on preventing future harm and improving IFC/MIGA's performance systemically. Learn more about CAO's Advisory role.
