The European Investment Bank (EIB) is a European Union financial institution that provides loans and financial services for sustainable projects, contributing to the development and integration of the EU member states. The EIB was established in 1958 under the Treaty of Rome, and it is the lending arm of the European Union. The primary mission of the EIB is to promote the economic and social development of EU member states by financing projects that align with EU policy objectives. These objectives include promoting innovation, climate action, and sustainable development. The EIB provides financing and expertise for a wide range of projects, including infrastructure, environmental sustainability, research and development, small and medium-sized enterprises (SMEs), and social projects. The bank's shareholders are the EU member states, and its decision-making processes involve representatives from these countries. It raises funds in the capital markets by issuing bonds. Its strong credit rating allows it to borrow at favorable rates, and it, in turn, provides loans on advantageous terms to its beneficiaries.
