How we work
Evidence alone does not change anything. It has to reach the people who can act on it, and those people have to be in a position to act.
Our theory of change is central to how we make change happen – how we shape our research and the interventions that drive policy change to address the global challenges in our manifesto.

What we’ve changed together
Our six priorities focus our research, partnerships and influence on tackling climate change, nature loss and inequality, and the unfair systems that drive them. Visit our impact page to find more.
Research excellence and impact
Ensuring that our evidence is of the highest quality is central to our credibility and policy influence. Find out more about how we work towards research excellence, including our commitments to integrity and ethics and quality standards.
Monitoring and evaluation
Ensuring we monitor and evaluate our work is essential to knowing the impact we have made alongside our partners. And we are also committed to continual learning – so we are delivering better research, working more efficiently and sharing lessons with others.
IIED’s values
IIED’s values are central to the work we do, and how we do that work. Prior to the launch of our manifesto in May 2024, we revisited our institutional values, and co-created this evolved set together.
How we communicate
Achieving the greatest impact means knowing when to communicate our research, whom to target, and what the right message is to make change happen.
Our communications work puts audiences first, creates impactful content and provides a framework for our communications to be as effective as possible.
