Maximising the effectiveness and transformative potential of international public finance and using it to leverage funds from other sources will be critical to implementing the Sustainable Development Goals and the Paris Agreement. In a context of scarce public resources for both development and climate action, it will be important to allocate public climate-related development finance where it is most needed and can be most effective and to use it in a catalytic way to leverage further public (domestic) and private sector investment to promote sustainable development. International public finance can increase private sector engagement, for example through use of risk guarantee instruments or blended finance arrangements. Development co-operation providers agreed to increase predictability and transparency of aid as part of the Busan Partnership.
