Interesting article. Newer numbers (2023) are 37.200 Mt CO~2~ yearly human civilisation output. "Private" cars count around 10% of that (which to my knowledge includes vans driven by tradesmen and "independent" delivery drivers among other uses, vastly distorting the impact of individual car ownership), aviation between 2 and 20% depending on which "emissions factor" the counting organization attaches to it. The IEA numbers vary between 2-4%.
