I followed the links of the information sources at the bottom of the page looking for the exact methods they used to measure either the impact of, or production of GHG emissions per capita per country.
I didn't find any actual measurements or methods of measurement, only speculation, prediction, and projection. There also seems to be a great many assumptions on the part of those presenting that sort of "data".
I always see either a lot of big round numbers thrown around or colorful map depictions, but never any actual measurement data or mention of any sort of error factors that would apply to such "data".
I've seen calculations of supposed CO2 production from burning X-amount of gasoline, but never any mention of just how much of it makes it to the upper atmosphere, how much is grabbed up by plant life near the ground, or how much Carbon falls to the ground as particulate. It seems to me that a great many steps have been skipped between calculation, speculation, and presenting of data/claiming conclusions.
Assuming that people actually went out and took real measurements, one would have to wonder if free accessibility to more areas or facilities in places like the United States had any bearing on the amount and accuracy of the data that was collected. I myself wonder how much of this "data" was collected by students from around the world that were doing research primarily supported by funding from "rich" countries. This area of "study" has been extremely popular with students lately, and apparently has received an ample supply of funding. One benefit would be funded trips to various areas of the world, to include places inside the United States. It would seem to be a pretty good deal for any student.
On this forum I've seen over-the-top skepticism applied against someone who is trying to sell "magic" spark-plugs, supposedly due to there being a conflict of interest between presenting non-biased data and achieving monetary gain. I have to raise an eyebrow when I don't see the same level of skepticism applied in other areas, for instance agendas that will result in substantial monetary gain for a government or governments.
