Applications of Carbon Dioxide Emissions Calculations in the Operation of Public Passenger Transport Systems

  1. Carlos Eduardo Sanches de Andrade

Abstract

This paper aims to analyze emissions from public passenger transport systems, metros and buses, compared with private cars, establishing calculating these emissions. The calculations were applied in the city of Rio de Janeiro, Brazil. The results obtained indicate that the electric trains of the system had an average emission of 4.5 g of carbon dioxide (CO2) per passenger-kilometer, a result 10 times lower than the emission of buses, which in turn emitted three times less than the private cars. The operation of metros and buses systems, thus, provided the city with significant reduction of CO2 emissions produced by the transport systems.
