The IEEP family

The IEEP family has existed for over 40 years and has very strong roots in the UK. The organisation has, in the past, been present in several European countries. UK exit from the EU gave rise to the decision to establish an independent, not for profit entity based in Brussels with similar objectives to that of IEEP UK based in London. As a result, there are now two legal entities which make up the IEEP family: IEEP UK and IEEP AISBL. The latter is based in Brussels and a Cooperation Agreement governs the relationship between the legal entities.


Based in Brussels, IEEP AISBL is a sustainability thinktank that works with stakeholders across EU institutions, international bodies, academia, civil society and industry, our team of economists, scientists and lawyers produce evidence-based research and policy insight.
