The InterAmerican Development Bank´s Sustainable Infrastructure Framework aims to help foster shared understanding of the key dimensions and attributes of sustainable infrastructure. It takes as a basis that sustainable infrastructure must consider the benefits and costs of investment over the entire life cycle, and that sustainability must be assessed based on economic/financial, environmental, social, and institutional dimensions. Within these dimensions, the framework also sets out 14 sub-dimensions. These sub-dimensions are the basis for organising 66 attributes that comprise the framework. Together, the dimensions, sub-dimensions, and attributes serve as a comprehensive framework for assessing the sustainability of infrastructure investments. The IDB Framework was adapted to Mexico after a thorough analysis of Mexico’s national development strategy and infrastructure investment priorities, in close collaboration with relevant stakeholders. In addition to providing a picture of the current state, the IDB Framework encouraged the adoption of good sustainability practices in the country and provided investors with sustainability information that aids investment decisionmaking.
