    Development of a Formula to Quantity Emlsslons Generated from Dlesel Vehicles in Sri Lanka
    (ACEPS-2017, 2017) Konara, K. M. T. N; Samarasekara, G. N; Chaminda, G. G. T; Dissanayaka, A. W; Perera, S. V. T
    Using the combination of optical properties of diesel exhaust and Beer Lambart law, particulate concentration was derved. Major component of the particulate matter of diesel exhaust was elė carbon which was derived from the optical properties of diesel exhaust. Characteriza emission composition was done through literature. According to the Spaciate 4.0 databa state environmental agency, characterization of diesel emission was finalized. Spaciate 4 the diesel exhaust is a primary combination of Organic carbon (31.80%), Elemental ca Sulphate (0, 67%), Nitrate (0.19%) and others including metallic components and etc.(6 that, a balanced chemical equation was formed for the incomplete combustion of the di air. Calculation of CO2, CO and PM was derived based on the stoichiometric ratio of the bäjä chemical equation.

    Energy and Environmental Implications of Green House Gas Mitigation Policies in the Transport Sector of Sri Lanka
    (IEEE, 2018-10-24) Fernando, G. L; Liyanage, M. H; Samarasekara, G. N
    This study analyzes the greenhouse gas mitigation policy options for the transport sector in Sri Lanka. It was carried out through the Asia-Pacific Integrated Assessment Model (AIM/Enduse), which is a bottom up type least cost optimization framework. A business as usual scenario and four alternative mitigation policy options were considered in this study. These policy options include two scenarios with 100 $/tonCO 2 , 500 $/tonCO 2 carbon tax, a subsidy scenario with tax rebates for electric, hybrid vehicles and a scenario which promotes pubic transport. The results show that the transport sector energy consumption is expected to increase from 5 Mtoe in 2015 to 19.5 Mtoe in 2045. The CO 2 emissions are expected to increase from 15 Mton in 2015 to 58 Mton in 2045. Out of the four scenarios, promoting public transport was most effective as it could reduce energy consumption by 52% and reduce CO 2 emissions by almost 36% in 2045. At current electricity prices and other costs, electric vehicles are not found to be economical in the analysis.
