Projected passenger car CO₂ emissions worldwide in the net zero scenario 2010-2050
Global passenger car emissions reached almost three billion metric tons of carbon dioxide (GtCO₂) in 2022. Under the IEA's Net Zero Emissions (NZE) by 2050 scenario, emissions from passenger cars would fall to below 500 MtCO₂ by 2040. This pathway would require the accelerated deployment of electric cars.
