Inventory of short lived climate pollutants (SLCPS) and PM2.5 from road transport in Rwanda

Abstract

This study has focused on the Inventory of SLCPS from the transport and their effect on the environment and human health in Rwanda and the data used were collected from the Rwanda Statistical Yearbook by taking the year of 2006 as baseline and the year of 2022 as end year in this inventory. The vehicles of different categories in Rwanda were recoded and analyzed under the model called:” Low Emissions Analysis Platform (LEAP)”. From the results analyzed and given by LEAP model, all my objectives were full-filled and it becomes easier to evaluate and characterize the emissions from different vehicles. In addition, by using the results from the model, the study of the effect of emission types and concentrations on human health and environment were achieved. The results show that fuels consumed and the emissions of SLCPs in the atmosphere were increased as well as the vehicles increased from 2006 till 2022. This study investigates from different sources the serious problems on the environment and also on the human health caused by Short lived climate pollutants from the road transport. These pollutants are known as the black carbon, Particulates of matter of diameter shorter than 2.5µm, Methane, and Nitrogen Oxide formed from the stratospheric ozone and ground –level or tropospheric ozone. Therefore, it was found that if left uncontrolled, the emission will continue to grow as the number of vehicles using roads is increased. This study shows some proposed mitigations methods facilitating in reduction of short lived climate pollutants which is introduction of hybrid electric vehicles.
