Simplifying the multi-layered and complex process through which new investment are considered and concession agreements are granted, as well as promoting more transparency around the decision-making process, particularly as related to how enviromnental and social issues are considered, should be prioritised. Lowering opportunities for discretion and unpredictability (see Chapter 5 on investment promotion and facilitation) could bring substantial benefits, not only in terms of more predictability and clarity for investors, but also by correctly assessing the true extent of social and environmental impacts of proposed projects. Requiring ex ante and ex post impact assessments is an important tool for examining, mitigating and preventing potential negative impacts of business activity.
