Our approach

We have delivered original, rigorous research that helps to drive progress, support sustainable development and protect the environment for over 50 years. Now we're offering different answers and approaches in order to achieve our mission.

With static five-year strategies not agile enough to deal with deep injustices and increasing unpredictability, our manifesto sets out our approach to tackling the triple crises of climate change, nature loss and inequality.

Manifesto for a thriving world


Partnerships are at the heart of our work – from citizen groups to multilateral organisations.

We work alongside over 350 partners in more than 60 countries to generate evidence and build capacity in order to drive change in policy and practice.

More about our partners


Our theory of change shows how we make change happen – from the way we monitor and evaluate our work to the way we communicate to drive policy change



We have a track record in finding solutions and testing practical approaches that deliver sustainable change. With partners, we put our insights into action. We scale them up. And we do it all to budget.
