This report aims to shift the investment needs debate away from a simple focus on spending more towards spending better on the right objectives using relevant metrics. It does so by offering a careful and systematic approach to estimating the funding needs (capital and operations and maintenance) to close the service gap in water and sanitation, transportation, electricity, irrigation, and flood protection.


Main conclusions include:

  • How much countries need to spend on infrastructure depends on their goals, but also the efficiency with which they pursue these goals.
  • With the right policies, investments of 4.5 percent of GDP will enable Low Middle Income Countries to achieve the infrastructure-related Sustainable Development Goals and stay on track to limit climate change to 2 degrees.
  • Infrastructure investment paths compatible with full decarbonisation by the second half of the century need not cost more than more polluting alternatives.
  • Investing in infrastructure is not enough; maintaining it matters.
