Keywords: Life cycle assessment, emissions and rail systems
Abstract: The study analyzes the Life Cycle Assessment (LCA) of rail systems in the United States and Japan. LCA assesses environmental impacts from the extraction of materials to the end of the system's useful life. Carbon dioxide - CO2 - emissions occur in several phases, operational and non-operational, such as construction and maintenance. The research addresses the literature of studies already carried out that consider CO2 emissions in the LCA of rail systems - subways, railways and maglev, showing that most emissions are the responsibility of the non-operational phase of rail systems.
