Faith + Reason = Truth

Wherever you stand on global warming, there are some hard data points to consider.  Countries can be ranked by how productive they are in terms of what they produce, be it for physical goods or co2 emissions.  I've summarized some data as follows:

24 countries contribute 1% or more of the world total man-made co2 emissions
These countries account for 84.3% of the total man-made c02 emissions
Man-made co2 emissions for ALL countries account for roughly .73% of the co2 in the atmosphere

Although man-made accounts for less than 1% of the total co2 in the atmosphere, it is not counter-balanced by natural processes, unlike the rest of the co2 in the atmosphere.  This "carbon cycle" is the process of co2 naturally released into the atmosphere by trees, oceans, dead matter, soil, volcanic eruptions, etc., and then re-absorbed by nature.  Our stuff throws things out of balance and leads to a net surplus in the atmosphere - very small, but measurable.  And nature's about to get into the act in a big way too, with unknown consequences, as described by this interesting Washington Post article (you may have to do a free registration to view it, unfortunately, but you should do one anyway because they frequently have great articles). 

The total GDP in $Millions divided by the total  co2 emissions of the top 24 emitters is $1.85, or 1.85 GDP units per co2 emission unit.  The higher your number, the more eco-friendly your GDP.  The U.S. is 9th out of 24 on this basis, at $2.12 (better than average).  Ukraine, Russia, Iran, India, and China range from $.27 (Ukraine) to $.68 (China).  France, U.K., and Italy are all better than $4.  Japan's the only Asian out of the best 13.  Here's a link to Wikipedia's "Carbon Cycle" article, along with a link to IMF figures for the GDP.
