Pollution, Climate: Europe s Approch to reduce GHG Emission and its Challenge 23% of total EU GHG emissions European Union s Greenhouse Gas Emission (GHG) Goal: Target Range for reduction until 2050 must be between 85% and 95% of 1990 s GHG Emission European Union s Binding Target: in 2030, 40% reduction of GHG (in 1990) Source: ICCT Transport Sector: Far away from targeted GHG reduction line Growth in Number of vehicles Increase of driven kilometer per vehicle (also trucks!) Trend to bigger cars Increasing gap of test-cycle findings and real-world emissions 2019-02-21 restricted Copyright Infineon Technologies AG 2019. All rights reserved. 5
