A policy brief by K. P. Gallagher, L. Serino, D. Bradlaw, and J. S. Serrate calls upon G20 leaders "to commit to scaling up resources by 25 percent, to calibrate new financing to international commitments to mitigate climate change and the 2030 agenda, and to work together as an inclusive system toward achieving those shared goals."

One initial proposal centres around the increase and optimization of capital of the Multilateral Development Banks (MDBs). The authors argue that the MDBs can provide much more financing while retaining their strong credit ratings. Public–private partnerships (PPPs) and blended finance can play a key role in bridging the finance gap for infrastructure, though they are not the solution for every infrastructure project. 

A second proposal calls to explicitly orient financing, institutional structures and internal incentives towards development impact. The Paris Agreement and the 2030 Development Agenda (including the Sustainable Development Goals [SDGs]) provide the guidance for what such impact should look like and how it can be measured. 

The final proposal focuses on the establishment of a multistakeholder forum involving businesses, governments, civil society and development finance institutions to strengthen global cooperation and governance.
