Title:

Bus Rapid Transit: Cost and CO2 Implications of Future Deployment Scenarios

Abstract:

The transport sector represents 18% of final energy use in the world and accounts for nearly 23% of worldwide CO2 emissions. To achieve a global 50% reduction in energy-related CO2 emissions by 2050 in line with the recommendations of the Intergovernmental Panel on Climate Change (IPCC) recommendations, the International Energy Agency (IEA) has outlined several CO2-mitigation scenarios including the IEA BLUE Shifts scenario where over 2 gigatons (Gts) of CO2 from transport are saved worldwide compared to a 2050 baseline projection, due in part to modal shifting from light-duty vehicles (LDVs) to public transit. This paper analyzes three different scenarios for increased use of bus rapid transit (BRT) by 2050, compared to a business-as-usual scenario, to estimate the CO2 impacts and cost-effectiveness of BRT as a CO2-mitigation intervention. The IEA’s Mobility Model (MoMo) is used as an integrated modeling framework to analyze the energy and CO2 benefits of worldwide deployment of BRT. In order to properly analyze BRT, a uniquely comprehensive database of all BRT systems in the world has been compiled so as to first and foremost establish an understanding of the characteristics of BRT today. This paper first presents findings based on IEA’s global BRT database, and then makes certain assumptions to analyze future deployment scenarios of BRT. Among the scenarios, cumulative savings are estimated to be 17-27% of CO2 emissions in the transport sector by 2050. Annual savings of CO2 emissions in the year 2050 are estimated to be in the range of 25-39%.
