This paper discusses country- and sector-level upstream planning and procurement approaches of water, transport, and energy infrastructure projects in Bolivia, Chile, El Salvador, Jamaica, Nicaragua, and Peru. For each country and sector, the paper analyses institutional frameworks and the policies and legislation relevant for sustainable infrastructure planning. The analysis covers the frameworks for countries to plan infrastructure at the upstream level, as well as procurement and contractual frameworks. The paper focusses particularly on how sustainability is integrated in such processes. The ultimate goal of this paper is to identify the main institutional gaps that need to be addressed in Latin American and Caribbean countries so they can improve their planning and preparation of sustainable infrastructure projects.
