Decarbonization Technology in Road Infrastructure Projects

Abstract

This study aims to determine the appropriate decarbonization technologies to reduce carbon dioxide (CO2) emissions in road infrastructure projects. Decarbonization is a process that seeks to reduce or eliminate CO2 emissions that contribute to climate change and that comes from the energy sources consumed by the transport sector. With statistical information from different studies, the most appropriate technologies were identified to control the triangle of effectiveness, productivity, and profitability derived from the costs, time, and quality of the projects associated with decarbonization technologies. The study is documentary and bibliographic, with the deductive method, quantitative approach, applied orientation, and descriptive, correlational, and explanatory types. The design is non-experimental, cross-sectional, and retrospective. The energy conversion efficiency of all technologies is identified in three domains: with fossil fuels from compressed natural gas, with natural gas, and with electricity by hydrogen electrolysis. GHG (Greenhouse Gas) emissions savings using BIM (Building Information Modeling) can reach up to 14% and 30% of emissions and 47% and 65% when the scope of maintenance and rehabilitation is restricted, and pavement construction is excluded.
