The white paper, titled \u201cThe Social Infrastructure Impact Investment Index (SI4)<\/strong>\u201d, introduces a new European framework for measuring and guiding impact investments in social infrastructure. Among the project\u2019s key partners is IFAB<\/strong>, which played a significant role in developing the model\u2019s methodological and technological foundations.<\/p>\n Developed through a collaboration between institutions, research bodies, and market stakeholders, the white paper addresses a pressing challenge: bridging the \u20ac1.5 trillion gap<\/strong> between existing investment and the actual needs in areas such as affordable housing, healthcare, education, and social care<\/strong>.<\/p>\n \u201cBuilding a reliable methodological framework to assess the social impact of investments is essential for attracting private capital and aligning with public policy objectives. Thanks to the use of advanced tools such as econometric analysis and artificial intelligence, the SI4 model marks a true leap forward for the European impact investing ecosystem<\/em>\u201d said Marta Carboni<\/strong>, Head of Innovation & Business Development and IFAB\u2019s lead on the project.<\/p>\n The SI4 Index is designed to serve as a quantitative and customizable tool for assessing and comparing the social impact of infrastructure projects, starting with a case study on social housing. The model integrates key European regulations (including CSRD and ESRS), ESG metrics, and best practices from the field, offering investors a reliable and transparent standard for evaluation.<\/p>\n The methodology is built on:<\/p>\nAn innovative framework for more informed investment decisions<\/h3>\n
