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 Klagenfurtís 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 žg/m≥ annual mean NO2 was computed for the city center and up to -1.5 žg/m≥ at kerbside locations compared to the BAU scenario 2025. For PM2.5
and PM10 the computed improvements are up to -0.1 žg/m≥ 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.
