Abstract

To better understand the impact of metro systems on reducing CO2 emissions in urban transport, a detailed analysis is required. This analysis should evaluate both the direct and broader effects of metro networks on the overall urban transportation system. It is crucial to quantify the actual contribution of metro systems in cutting CO2 emissions by considering the entire transport network. The evaluation should include not only the emissions generated by metro operations but also the reductions achieved by decreasing reliance on higher-emission modes like cars, buses, and motorcycles. From an engineering perspective, metro systems can improve urban mobility efficiency by increasing passenger capacity, reducing traffic congestion, and enhancing the energy efficiency of public transport. Replacing private vehicles and buses with high-capacity rail systems can significantly lower per capita emissions and enhance air quality. Additionally, the energy source powering metro systems, particularly electricity from renewable sources, plays a crucial role in reducing the carbon footprint of urban transportation. This work aims to develop a comprehensive methodology for estimating CO2 emissions, accounting for both the emissions directly produced by metro systems and the emissions avoided due to their operation. By integrating transport engineering concepts such as vehicle-kilometer reductions, energy efficiency measures, and modal shift effects, this methodology will assess the net environmental benefits of metro systems. The findings will highlight the key role metro systems can play in supporting sustainable, low-carbon urban transport systems, aiding in the planning and development of future infrastructure that balances environmental performance with high-quality service and connectivity.
