The Executive Session on the Politics of Extractive Industries (ES on PEI) is a policy innovation lab led by a group of experts - academics and practitioners - from across the world. Focusing on PEI entails grappling with the ways in which power, interests, incentives and characteristics of political systems shape how extractive industry projects are developed, their ultimate outcomes, and often the fate of governance interventions designed to improve these.The purpose of this group is to produce practical insights, new strategies, and tangible guidance to address a major challenge confronting all those hoping to improve outcomes from extractive industry development: the political aspects of the governance of the sector.
