International Climate Finance: Innovation, Collaboration, and Challenges

International public finance is essential for global collaboration on climate change. With the deepening climate crisis and stagnant public finances, it is essential to maximize the impacts of limited resources, especially in the developing world. To this end, new public climate organizations have emerged, and existing multilateral and bilateral mechanisms have made innovations to improve climate finance.

To assess these trends, this symposium assembled experts in climate change finance from multilateral, minilateral, regional, national, and philanthropic organizations. The meeting enabled practitioner-researcher exchange on innovative practices, lessons, actionable insights, and challenges ahead.

The symposium took place at Leiden University (Campus The Hague) on 10–11 April 2025. Panels respectively addressed innovations in established multilateral climate finance, new climate finance donors, and academic and policy research on emerging trends of international climate finance.
