> The simplest approach, administratively, is to levy the carbon tax “upstream,” where the fewest entities would be subject to it (for instance, suppliers of coal, natural gas processing facilities, and oil refineries).

Include other highly polluting industries with that, and while you may not get 100% coverage, it would definitely cover the majority of carbon intensive products and services and lead to a drastic reduction in emissions.

CCL estimates that the annual administrative cost of a carbon tax in the US would be about $4 to $5 billion per year, which is about 6.8 percent of revenues in year one ($15/ton of CO2e year one, rising by $10/ton each year), but as revenues grow along with the fee, it drops to only about 1.7 percent by year 10.
