In order to respond to the research question that seeks to better understand how digital technologies can enhance green finance within the Swiss context and provide policy insights, UN Environment, with support from FOEN, has undertaken a stocktaking of the green digital finance ecosystem. The aim is to map green digital finance practices both internationally and in Switzerland and draw recommendations for harnessing the potential of green digital finance to realign financial flows to a low-carbon and more resource-efficient pathway. The scope of the research was defined, based on relevance to the Swiss context, and its contribution to global thought leadership in this area. A review of the international and Swiss green digital finance landscape was carried out (Sections 2 and 3). Based on this, the current research focuses on how digital technologies can improve financial decision-making and access to green finance, such as increasing the availability and use of environmental data as well as the integration of ESG factors. It also looks at how digital finance can transform current consumption and production patterns towards resource efficiency and sustainability, by creating opportunities for greater citizen engagement; as well as the relationship between digital finance and business model innovations in the real economy. Covering the whole spectrum of the financial industry, the report focuses on banking, investment and insurance. This includes private banking and wealth management, subsectors that Switzerland is well known for. In terms of the technology ecosystem, the report focuses on the underlying technologies outlined in Box 1, as these relate to financial decision-making and access to green finance. It also covers the opportunities and challenges related to cryptocurrency in light of Switzerland’s leading position in this area.
