A quick search suggests %90 percent of human caused CO2 emission is from fossil fuel consumption (things like calcium carbonate produce half of cement emissions). All cause emissions of CO2 dwarfs human emissions, but as part of a cycle that consumes CO2 as well.

Here's the paper: https://www.nature.com/articles/s41597-025-06391-w
And the data as a bunch of zipped geotiffs: https://zenodo.org/records/15446748
A reasonable-ish resolution version of the headline image (total CO2 emissions 2010-2022): https://media.springernature.com/full/springer-static/image/...
And my favorite: Difference in CO2 emissions between 2010 and 2022: https://media.springernature.com/full/springer-static/image/...

“The output constitutes many terabytes of data and requires a high-performance computing system to run,” co-author Pawlok Dass, a SICCS research associate, said in the release.”
The largest zip file I see on the zenodo link is 404 MB in size, I’d be surprised if it unzips into anything more than a few gigabytes.

I think the clue is in the sentence "this map is actually a high-level visualization of the data Vulcan provides". The source data is terabytes of data, they boiled it down to a couple of maps with 1 square kilometer resolution. Maybe the next data releases will contain more.
I don't have a clue how we go from this dataset to "down to every city block, road segment and individual factory or power plant". I guess some refineries can be measured in square kilometers, and it's a pretty good resolution for looking at highways, but other than that it seems like an exaggeration.
