There are two ways of doing the accounting, and the more common one is from the producer side such as by industry, by country, by use. Our world in data is linked in a sibling comment, for the breakdown of the transport side. As is the California ARB inventory. There are other national inventories. One thing to be very careful about is people making arguments for a national or local policy, that uses worldwide inventory numbers rather than an inventory applicable to where the policy applies. I see this a lot with local old New Leftists trying to argue that their old Toyota Tacoma isn't a big deal, but everybody had better become vegetarian right away, because worldwide beef accounts for a much larger proportion than cars (but locally cars dwarf anything from food production) And the production side inventories are very poor at making consumption level decisions, because people always complain that we've merely shipped all our production emissions from manufacturing to China. In reality there are great Our World In Data pages showing that yes, cars really are much bigger emitters for Americans than exporting emissions to Chinese manufacturers. So my favorite inventories of climate emissions are consumption based, and show that lifestyle is one of the biggest drivers of climate emissions in the US: https://coolclimate.berkeley.edu/maps There are rich cores of cities that are very low emission, surrounded by wealthy suburbs with sky-high emissions, and then rural areas with very low emissions. EVs have the chance to change high emission wealthy suburb life into low emissions. But if we simply legalized more housing in the wealthy city cores, it would allow a lot more people to choose to have lower emission lifestyles right now without technology change, while also spurring massive economic growth. | ||
