Let's try to deduce this number.

According to https://www.acea.auto/files/ACEA-report-vehicles-in-use-euro... in 2023 there had been ~294M passenger cars registered (on the road) in EU+EFTA+UK (page nr 4).

Roughly around 93% of those ~294M passenger cars are either petrol or diesel, so ~274M (page nr 14).

According to https://www.acea.auto/figure/average-co2-emissions-from-new-... the average CO2/km consumption for new cars is 110g.

Let's correct this figure so that it also includes the older cars so let's assume that the CO2/km consumption is 130g.

Let the average passenger car distance travel be 15k km a year.

274M cars * 15k km * 130g = 5.343×10¹⁴g = 0.5343 billion tonnes.

So, only 10% of total CO2 emissions from Europe and 0.01% of total CO2 emissions in the world?

> Sadly this isn't true.

CO2 emissions from fossil fuels is 38 billion tones in 2023 (https://ourworldindata.org/co2-emissions)

Oceania: ~0.5 billion tones

Aviation: ~1 billion tones

Africa: ~1.5 billion tones

Europe: ~5 billion tones

America: ~7.2 billion tones

Asia: ~22.5 billion tones

This includes the fossil fuels from the whole industry and not only the civil transportation. Europe constitutes ~13% of total (world) emissions.
