Evaluation of E-mobility benefits in Klagenfurt Air pollutant and GHG reduction

Research output: Contribution to journalArticle

Abstract

Promoting E-mobility in Klagenfurt and realizing environmental co-benefits are major objectives of CEMOBIL. In Klagenfurt, there is a high share of light diesel vehicles (> 60 % VKT) and NO2 levels at air quality stations have remained high near major roads within the last couple of years. Due to Klagenfurt’s location in a sheltered alpine basin, there is a strong sensitivity of air quality towards emissions released close to the ground. The impact of increased E-mobility (20 % electric light vehicles, 25 % electric buses) in the Klagenfurt area was assessed for 2025 and compared with a BAU 2025 reference scenario. Additional electricity related emissions were estimated. Emission reductions were computed for CO2 (-14 %), NOx (-8.8 %) and PM10 (-0.6 %). An area-wide reduction potential of -0.8 μg/m³ annual mean NO2 was computed for the city center and up to -1.5 μg/m³ at kerbside locations compared to the BAU scenario 2025. For PM2.5 and PM10 the computed improvements are up to -0.1 μg/m³ at busy roads. The comparison BAU 2025 versus Base 2014 revealed that the reduction potential of improved exhaust aftertreatment technologies along with fleet renewal is larger than the E-mobility reduction potential for NO2 and PM.
