Evidence Dialogues series: what works for investing smarter in climate action

About the event

Climate change is one of the defining challenges of our time, yet rigorous evidence on how to address it is not informing the large public investments flowing into climate action. Analysis from the Center for Global Development suggests only a tiny fraction of almost USD 100 billion in annual public finance is supported by rigorous evidence on what works, for whom, and at what cost. The cost of failure is potentially catastrophic, making investing in evidence-informed climate action a cheap insurance policy we can no longer afford to ignore.

This three-part Evidence Dialogues series, convened by 3ie in partnership with What Works Climate Solutions, brings together experts to take stock of where the field stands and to ask, collectively, what it will take to build a stronger, more inclusive evidence ecosystem for climate action.

Through these discussions, we explore what current evidence tells us, why building support for rigorous evaluation has proven so difficult, and how the field can work together to strengthen demand for evidence and embed it in climate decision-making. The series is designed to stimulate the cross-sector dialogue and collective action that the climate evidence agenda urgently needs. This really is a time when trusted evidence on what works is needed more than ever.

Our series is a catalyst for a broad, field-wide effort to strengthen the evidence ecosystem for climate action. The climate evidence field has the knowledge, the networks, and the momentum to do much better – and this Evidence Dialogues series is our invitation to make that change happen together.
