Cost-benefit analysis and risk management tools traditionally used by financiers, including public authorities, to achieve a higher degree of transparency regarding any infrastructure project’s assets, liabilities, equity, reserves, expenses, profit, and loss. In the context of sustainable infrastructure, these tools can help facilitate an understanding of the impact of sustainability performance and externalities on a projects’ economic value, cash flow, and returns. These tools can be used at an early stage to support the decision-making process as well as in later phases to evaluate performance.
