We are the movement that accelerates the transition towards the Impact Economy, an economy in which:

  • Work, innovation and entrepreneurship contributes to resolving our societal challenges.
  • Impact accounting puts societal value creation and contributing to the SDGs at the heart of every single organisation.

  • Sustainable, responsible and regenerative entrepreneurship is easier and more profitable than business as usual.

To accelerate the transition to the Impact Economy, IEF works together with companies, executives, NGOs and governments to develop the mindset, instruments and incentives for the Impact Economy.

Our Mission

The Impact-Weighted Accounts Framework

The Impact-Weighted Accounts Framework (IWAF) forms a center piece of the Impact Economy. IWAF provides organisations with a harmonized, consistent way of measuring, reporting and steering on impact. The framework helps to quantify and monetize organisations’ impact on social, human and natural capital for all stakeholders.

This framework is the result of a partnership of the Impact Economy Foundation (IEF) with Harvard Business SchoolSingapore Managementuniversiteit,  Rotterdam School of Management en Impact Institute.

The National Conference on Broad Prosperity brings together the pioneers of the Impact Economy. The pioneers come annually together to monitor progress, be inspired, get energized and accelerate the transition to the Impact Economy.


A Chief Value Officer is an executive who not only steers at financial value creation, but at the creation of positive societal impact (the combination of social, human, natural and financial capital). IEF provides a platform to CVOs by annually awarding the CVO of the Year Award.
