The aim of this paper is to provide a detailed analysis of the emerging concept of sustainable securitisation, using case studies to demonstrate examples and the prevalence of this concept. For writing this paper, secondary data and research method that include the descriptive method, analysis and synthesis method, as well as the comparative method were used. Current global investments in the low-carbon transition are insufficient, which has led the market to recognize the potential of securitisation, more precisely, in its sustainable form. Sustainable securitisation is closely related to the ESG indicators, which have become crucial in business today, mainly driven by regulatory frameworks that have been established, especially in the EU. As a relatively new concept, sustainable securitisation aims to facilitate financing for ESG-aligned assets while providing additional sources of funding to market participants for whom such investments are becoming increasingly important. Sustainable securitisation expands the range of potential investors who have strong interest in directing capital toward projects that meet the global transition objectives. Case studies illustrate how the observed countries, that include the United States, the Netherlands and China, are applying sustainable securitisation in different sectors, along with the automotive industry that is gaining importance in this new concept. They provide insights into the diversity of sustainable projects that can be financed through securitisation. There is a significant disparity in development among the observed economies, which also impacts the geographical prevalence of sustainable securitisation. The paper presents the prevalence of both the traditional securitisation instruments as well as new forms of esoteric securities that have emerged within this new concept. When analyzing the concept, it is necessary to consider numerous factors, as well as current market deficiencies, particularly in the area of regulatory frameworks whose absence slows down futher development. Concerns and urge for climate neutrality have prompted numerous global economies to place various restrictions to prevent further impact of climate change. Therefore, sustainable securitisation is considered as one of the most significant technique in today's financial world.
