The European Investment Bank (EIB), established in 1958 and headquartered in Luxembourg, operates primarily in the finance sector, focusing on banking, investment management, and venture capital. With a workforce ranging from 1,001 to 5,000 employees, the EIB engages in various financial activities, including investment banking and insurance. The EIB's published documents reflect a commitment to promoting the circular economy, as evidenced by the "EIB Circular Economy Guide" released in May 2023, which outlines the bank's support for circular transition projects and the associated EU policy framework. This guide discusses the benefits of circular economy models, including risk reduction and cost savings for businesses, while also emphasizing the importance of urban areas in facilitating resource collection and reuse. Additionally, the EIB has produced case studies that highlight practical applications and outcomes of its initiatives. Through these documents, the EIB demonstrates its role in fostering sustainable economic practices and addressing contemporary financial challenges within the European Union.
