The Sustainability bonds aim to finance sustainable green investments or social investments. These are in line with the sustainable development objectives previously published by Flanders in the context of "Vision 2050" and "Vizier 2030". Specifically, the means will be used to increase the energy efficiency of buildings. In addition, affordable housing is financed and a part of the funds is intended, among other things, for the construction of (passive) schools within the framework of the DBFM Schools of Tomorrow. Finally, Flanders will also finance initiatives in the circular economy with these resources in the future.
