Assessment of energy consumption, environmental effects and fuel costs of the bus rapid transit system in Bogotá (Colombia)

Abstract

Colombia aims to boost the utilization of mass transportation systems in its major cities while simultaneously reducing greenhouse gas emissions by 20%, in alignment with the commitments of the COP21 agreement. In 2020, the transport sector in Colombia accounted for 34.4% of the country’s energy demand and was responsible for ~49% of its total CO2 emissions. This article presents an assessment of energy consumption, environmental effects and the fuel costs of Bogotá’s bus rapid transit system based on the Activity, Share, Intensity, Fuel methodology. A long-term analysis spanning from 2021 to 2040 was developed using the long-range energy alternatives planning platform. To conduct this assessment, the tool was calibrated using data from 2019 and 2020. Four distinct scenarios based on energy policies implemented in Bogotá were examined: Business as Usual, Fast Transition, High Growth and Low Growth. Regarding energy consumption and environmental effects, the results underscore the pivotal role of diversifying energy sources and reducing reliance on fossil fuels such as oil. Consequently, the analysis emphasizes the urgent need to accelerate the transition to alternative energy sources such as natural gas and electricity.
