Review of Financing Mechanisms to Promote Decarbonization Alternatives in Rail and Inland Waterway Transport

Abstract

The financial market has a strong influence on supporting the transition to a zero-emission transport system, as this sector requires large investments to implement low-emission technologies and infrastructure and to promote intermodality. This article presents the results obtained from a literature review on the financing mechanisms that have been used in different countries to finance alternatives to decarbonization in rail and inland waterway modes. For this purpose, databases such as Google Scholar, Scopus, MDPI, websites of governments and other related organizations were reviewed. Over 240 sources of information from articles and documents focusing on green finance in rail and inland waterway modes were reviewed. Our study identified many gaps in the literature on green transport financing. We also identified that in the databases consulted, it was possible to obtain more academic sources related to rail transport than inland waterway transport. Finally, an analysis is made of how implementation projects in the rail and inland waterway modes have been financed in Colombia.
