I wonder what the breakdown is between personal and commercial vehicles.

  The link above spells it out. 58% of transportation emissions were from "light duty vehicles", and 24% were from trucks.

    Light duty vehicles doesn't necessarily mean that they're personal vehicles.

Aren't all these statistics able to be infinitely nitpicked since nobody can agree on which bucket to sort the emissions into? Example: a car is produced, does the responsibility for the emissions go to the manufacturer or the consumer who buys the vehicle? Now do this for every single part and bucketful of metal ore down the chain of suppliers, manufacturers, shippers etc. Drawing a line seems difficult and how do you even know whether you double counted at any point.

  The vast majority of industrial production, world-wide, goes to middle and upper class consumption, across the board. From cars to cell phones to pharmaceuticals to beef to central heating. We either get more efficient at making it or consume less.

  Not hard. Manufacturer emissions from production. (Costs just passed on to consumer but that means lower sales and smaller tam until they make lower emission vehicles) Consumer emissions from use

Just going one step above: https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emis... Agriculture and Industry represent 33%, more than the 29% of the total for transportation. Even drilling down transportation, personal vehicles are a small portion (about a fifth ?) of the total compared to trucking and other business vehicles https://depts.washington.edu/trac/bulkdisk/pdf/VVD_CLASS.pdf https://depts.washington.edu/trac/bulkdisk/pdf/VVD_CLASS.pdf And I'd expect their emissions to be way lower than trucks and heavy duty vehicles. We could drill down the other categories (electricity, commercial and residential -- btw it's so absurd to merge these two in one block), what we individually consume/burn as private citizen is usually the tip of the iceberg. Consuming less or different can have an impact, but only if the industries behind also follow through (image for instance you stop eating meat to reduce the agricultural impact, only for the soybean producer to go on a production rampage and destroy soils and areas in ways we wouldn't have predicted). Or from another perspective, we could have significant impact from the producers improving their practices, with little to no consumer behavior change. Basically nothing will happen without the production side making a significant effort. If what we're looking for is "doing something", pushing harder on producers should be the way to go.
