Since 2001, the European Commission has embraced the notion of sustainable to address the challenge for a development combining economic growth, social cohesion and environmental protection. In this context, stimulating energy efficiency, renewable energy production and management systems is crucial. The goal for the evaluator of a complex program aiming to achieve energy-saving interventions, increase the consumption of renewable energy and reduce the greenhouse gas emissions is to adopt an integrated approach to contempt the smart, sustainable and inclusive growth of sustainable development. This article, starting from the evaluation of the interventions of Priority 2. Energy Regional Operational Programme ERDF 'Lombardia' 2007-2013, reflects on the effects of smart, sustainable and inclusive growth, and on which suitable assessment tools bring out the direct and, above all, indirect effects created by investments.
