Public Financial Institutions and the Low-Carbon Transition: Five Case studies on Low-Carbon Infrastructure and Project Investment

COP30 concluded with an agreement, proving that multilateralism is still alive. However, the results are underwhelming: no push to transition away from fossil fuels, no decision on deforestation, and mixed outcomes on adaptation metrics.  On climate finance, Belém failed to shift from ambition to implementation. Negotiations quickly drifted back to a battle on yet another high-level quantitative target. The decision to triple adaptation funding by 2035 disappointed many, with its distant time horizon, lack of baseline and non-binding wording. COP30 also missed the opportunity to engage with – and build consensus around – concrete measures outlined in the Baku to Belém roadmap to get to $1.3 trillion. Instead, it defaulted to launching new processes – a work programme on climate finance and a ministerial roundtable on the NCQG.  

The climate and development finance gap is large and widening, as Official Development Assistance (ODA) declines and needs multiply. With shrinking fiscal space in vulnerable countries, solidarity levies are gaining attention as a predictable source of international finance. Launched at COP28 by Barbados, France, and Kenya, the Global Solidarity Levies Task Force (GSLTF) is the main initiative in this space.

National Public Banks (NPBs) and Subnational Public Financial Institutions (SPFIs), including development banks and agencies as well as climate and green funds at the subnational level, play an increasingly vital role in financing climate action and the just transition. While national governments provide frameworks aligned with nationally determined contributions (NDCs), actual implementation occurs largely at the subnational level, which currently lacks sufficient funding. SPFIs can work as financial intermediaries, as they not only understand local needs and have stronger ties with local governments and businesses, but also access much larger volumes of capital from more diverse sources.
