The Three Pillar Assessment (3PA) consists of three pillars each of which represents a key dimension of quality project assessment providing a clear framework within which project proposals can be evaluated. Pillar 1 addresses the "why?" of the project. In this pillar, Bank staff rate the project's contribution to EU policy objectives and establish whether it falls within one of the high priority areas for achieving those objectives, such as cohesion or climate action. Pillar 2 relates to the question "what?". The project is assessed for quality and soundness in terms of what it will contribute to growth, environmental and social sustainability, as well as employment. Pillar 3 looks at how the EIB's contribution will ensure the project's success in terms of the Bank's financial and technical contribution.
