According to data from the World Bank Enterprise Surveys from 2010-2017 in developing countries, access to finance is the foremost barrier to firm development (World Bank, 2017, Figure 1.1). These financial constraints are exacerbated for green growth and climate action in which the private sector is sometimes reluctant to invest, in part, to a lack of proven and readily available business models or a failure to understand the business case. Development cooperation can address both the demand side and offer side of the access to finance equation. On the one hand, it can stimulate demand for clean technologies, for example, by raising awareness and demonstrating the business case.
