Environmentally Sustainable Urban Transportation--Comparative Analysis of Local Emission Mitigation Strategies vis-a-vis GHG Mitigation Strategies

Local policy makers must make a tradeoff between global emission mitigation strategies (GEMS) and local emission mitigation strategies (LEMS) and choose the one that provides the best bargain in the urban transportation sector. This study compares GEMS and LEMS and investigates their potential in controlling non-target pollutants/emissions in concurrence with their economic performance. Findings showed that strategies targeted at the mitigation of local pollution like total suspended particulate matter (TSP) and hydrocarbons (HC) also show greater potential in reducing carbon dioxide (CO2) emissions (as non-target emission). In GEMS, 20% CO2 reduction resulted in 14.9% reduction in TSP emission. In LEMS with a 20% TSP reduction, CO2 emission reduction was found to be 15.2%. TSP mitigation strategy not only performed well with non-target global emission but also within local emissions, with sulfur dioxide reduction much higher than that of target pollutant. The HC mitigation strategy was found to be under-performing with most of the non-target pollutants lying far below the target pollutant reduction. The total cost of transportation was found to be in a similar and smaller band in both GEMS and LEMS. The HC mitigation strategy resulted in the least cost, followed by the CO2 and TSP strategies. These findings indicate that employing local pollutant mitigation strategies in transportation planning would also cater to the needs of GHG mitigation.
