The Impact Report offers a fresh and accessible look at how the IDB Group is working to achieve impact across Latin America and the Caribbean. Formerly known as the Development Effectiveness Overview (DEO), the report offers insights about effective and novel approaches employed by the IDB Group--comprising of IDB, IDB Invest, and IDB Lab--to promote inclusive growth and sustainable development, in close collaboration with the public and private sectors. 

The 2025 edition puts a spotlight on infrastructure, showing how expanded access to water, sanitation, energy, and transportation is transforming communities. More than just a report, it serves as a gateway to the IDB Groups broader efforts to ensure accountability, as well as track, evaluate, and learn from development results. It offers readers a clear view into what is working, what needs improvement, and how the Group continues striving to achieve a meaningful impact across the region.
