Leveraging blockchain technology for innovative climate finance under the Green Climate Fund

Abstract

The rapid development of digital technologies such as blockchain and distributed ledger-based systems holds transformative potential for the financial sector. Promising applications include asset management as well as peer-to-peer networks for the transparent exchange of data and information. International climate finance stands to benefit in particular ways from these new opportunities in financial technology. Distributed ledger technologies could be leveraged to support climate action, for example by facilitating transparent and standardized transactions, or by enabling more efficient monitoring and accreditation processes. In view of these promising opportunities, we focus our inquiry on the case of the Green Climate Fund to explore how distributed ledger technologies can be used for innovative climate finance. Based on our analysis of different digital system models and potential use cases, we then discuss some of the technical and political challenges that may arise, for example with regard to standards and safeguards, governance processes, country ownership, and further capitalization. Our findings show that distributed ledger-based systems could benefit the work of the fund in key areas such as multi-stakeholder coordination and impact assessment. However, our analysis also points to the concrete limitations of technology driven solutions. Digital technologies are not a standalone solution to persistent resource allocation and governance challenges in international climate finance, especially because the design and deployment of these digital systems is inherently political.
