African Development Bank

The African Development Bank (AfDB) is a regional multilateral development finance institution established to contribute to the economic development and social progress of African countries that are the institution’s regional member countries. The AfDB was founded following an agreement signed by member states on August 14, 1963 in Khartoum, Sudan, which became effective on September 10, 1964. The AfDB comprises three entities: the African Development Bank, the African Development Fund and the Nigeria Trust Fund. The AfDB headquarters is officially in Abidjan, Côte d’Ivoire.

As the leading development finance institution on the continent, the AfDB’s mission is to help reduce poverty, improve living conditions for Africans and mobilize resources for the continent’s economic and social development. The AfDB promotes the investment of public and private capital in projects and programs that are likely to contribute to the economic development of its stakeholders. The bank therefore finances projects led either by the government or the private sector.

European Investment Bank

The European Investment Bank (EIB) is the European Union's bank and is the only bank owned by and representing the interests of the European Union Member States. It works closely with other EU institutions to implement EU policy.

As the largest multilateral borrower and lender by volume, EIB provides finance and expertise for sound and sustainable investment projects which contribute to furthering EU policy objectives. More than 90% of its activity is focused on Europe but EIB also supports the EUs external and development policies. EIB generally finances one-third of each project but it can be as much as half. This long term, supportive financing often encourages private and public sector actors to make investments which might not otherwise be made.

EIB supports projects that make a significant contribution to growth and employment in Europe. Its activities focus on four priority areas:

The European PPP Expertise Centre (EPEC) is a part of the EIB’s Advisory Services, the purpose of which is to strengthen the public sector’s ability to deliver sound PPPs, thereby helping to provide public infrastructure and services effectively and efficiently. EPEC is a 40-strong membership-based expertise network of central and local government PPP Units, which provides a unique platform for the exchange and dissemination of good practice across Europe, facilitates Members learning from each other and provides a focus for providing and receiving technical support. EPEC does this through Member network activities (including EPEC thematic publications), bespoke policy and institutional advice provided to Members on an individual basis and bilateral upstream PPP project support to public authorities. These activities help the public sector across Europe to develop better PPP policies and prepare, procure and manage better PPPs.

Global Infrastructure Hub

Launched in 2014 by the G20, the Global Infrastructure Hub (GIH) is the only organisation dedicated solely to infrastructure in both developed and emerging markets.

GIH works with both the public and private sectors to facilitate knowledge-sharing, highlight reform opportunities, support the adoption of leading practices and help to build the global pipeline of quality, bankable infrastructure projects.

They are independent, with the agility of a start-up and the credibility of an international organisation, providing all tools and services on an open and free to access platform.

GPRBA focuses on targeting low-income households who would otherwise go unserved to ensure no one is left behind and to address the issues that contribute to poverty, inequality and discrimination to improve the socio-economic status of those that are marginalized. 

Results-based financing is a complementary approach to PPPs, sharing similar goals and attributes. Both work to mobilize private capital and increase performance efficiencies in the delivery of basic services. GPRBA’s portfolio includes a number of PPP projects, in which results-based financing has been successfully utilized to ensure the results are reaching marginalized populations, delivering access to electricity, water, sanitation, health care, education and other basic services necessary for growth and opportunity.
