This working paper focuses on understanding the concept of ‘bankability’ in support of the development of quality climate project proposals – to assist countries’ access to international climate finance. The Green Climate Fund is currently the largest multilateral climate fund, and climate change and development practitioners alike are focused on seeing these resources flow. The Green Climate Fund represents a critical source of climate finance for developing countries and the fund has been at the centre of future prospects for financing climate change action. The climate finance landscape extends beyond the parameters of the Green Climate Fund, however, and the availability of funding from various sources – national and international, public and private – means that the climate finance arena is a complex and dynamic one to navigate.
