This report makes the case for a big investment push for EMDEs' sustainable recovery and development, assesses the magnitude and composition of such investment, presents actions needed for an energy transition, looks at the role that innovations and state capacity can play in facilitating GRID, and proposes actions that governments, the private sector, MDBs, the IMF, and donors can undertake to mobilize financing at the large scale needed. The report summarizes the insights derived from the meetings of the High-Level Advisory Group (HLAG) on Sustainable and Inclusive Recovery and Growth, jointly led by Mari Pangestu, Ceyla Pazarbasioglu, and Nicholas Stern, and composed of experts from research institutions, the private sector, and governments, as well as senior World Bank Group and IMF staff members. The work of the HLAG, and thus this report, focuses on EMDEs and delves in greater depth into climate investment and financing, particularly for energy transition, as it is a less researched area. While doing so, it recognizes that policy and investment decisions in high-income countries, which accounted for only 16 percent of the global population in 2019 and yet for 32 percent of total greenhouse gas emissions (World Bank 2023a, 2023b), will be critical to whether the Paris Agreement goals can be reached. It also recognizes that these countries must play a key role in contributing financially to EMDEs' transition to low-carbon economies.
