I do love a diagram. (While it says 2016, it was produced in 2020 and it’s the most exact numbers we have as of now; takes a while for exact numbers to trickle down in every industry). So people saying “it’s cars,” “I think it’s deforestation?”, “it’s cows farting,” (I did appreciate that one), here are your answers.
All road transport (not just cars but every vehicle: buses, lorries which are huge polluters and heavy travelers): 11.9%
Cows farting (they called it livestock and manure): 5.8%
Deforestation: 2.2%
And so on.
It includes just about every industry you can think of that contributes, from aviation to cement to crops burning.
AND THE BIGGEST CONTRIBUTOR?
Energy use in industry*: 24.2%
So. It’s not driving. It’s driving to the store, buying things, and the industry that makes those things.
*includes industries of iron and steel, chemical and petrochemical, other metals (probably producing the stuff in cell phones), and “other industry,” which would include things like the factories that make fast fashion or plastics
