[PO02] CO2 emissions of personal vehicles
Pressures

Key message
Bad

Specific CO₂ emissions from new passenger cars amounted to 127 g CO₂/km in 2024 and decreased to 117 g CO₂/km in 2025. The increase in the share of electric passenger cars contributed significantly to this reduction. Nevertheless, the target value for the 2025–2029 period, set at 93.6 g CO₂/km, has not yet been achieved.

In 2024, average CO₂ emissions from all passenger cars amounted to 157.5 g CO₂/km and changed only marginally compared with 2023. The target value for 2020, set at 152 g CO₂/km, therefore remained unmet.
