Abstract

It is established that the interprovincial transportation in bus terminals of the Cities such as Ambato, Riobamba, Salcedo, Latacunga and Guaranda have contributed to the build-up of external costs of Greenhouse Gases (GHG) The climate change costs are calculated by multiplying the carbon emissions by the cost factor. To quantify the GHG emissions, this study has taken into account of both the direct and indirect sources of the Greenhouse Gas Protocol (GHG), as well as the ISO 14064.1: 2006 standard. In view thereof, it was found that the 11 bus terminals of the five cities, namely Latacunga, Riobamba Salcedo, Ambato, Guaranda-which accounts for around 3225 buses, had accounted for the emissions of 25,746.8 tCO₂eq, 37,404.6 tCO₂eq, 8,762.7 tCO₂eq, 92,364.9 tCO₂eq, 31,990.3 tCO₂eq, respectively. Simply, the average load of such pollution produced per vehicle was 60.8 tCO₂eq. and the total emissions were 196,269.3 tCO₂eq with an estimated GHG contamination cost of €27,477,702 per year.
