How much CO2 Equivalent (CO2E in reference to all green house gases
and is calculated based on their Green House effect relative to CO2's
green house gas effect, e.g. I think methane is 21 or 22 times more
potent of a GHG then CO@ thus count as 21 or 22 CO2E)is
produced/emitted by shipping anything:
      -on a per weight per dollar basis?
          - I want to know if someone is paying $10 per pound on average for 
            there freight then xxxx lbs. of CO2E is being produced for ever $ 
            spent or every pound shipped. I want that for $0.10-250 per pound    

- I would say probably the best way to do this is figure out on
average how much CO2E produced per dollar spent for each type of
shipping (freight by truck, by water, by ground (UPS, USPS, FedEx and
UPS), by express (UPS, USPS, FedEx and UPS), by next day (UPS, USPS,
FedEx and UPS))
- Once you have these data point you put them on a chart and use a
regression model to come up with a formula that will produce the CO2E
produced based on two variables either the total weight and the total
dollars spent on shipping, or based on the total weight and the
average dollars spent per unit of weight. Either of these formulas
would be acceptable.
- please use 2006 dollars when it comes to inflation. So if what you
find is in 2002 dollars please translate that into 2006 dollars
- Please include all calculation and all sources for where those methods came.
- I need the source of your information and it should come from
Academic Journals (A to B rated journals) or another very credible
sources. The source is key! It has to stand up to very critical
academic experts.

I have info and access to the Economic Input Output Life Cycle
Analysis (EIO-LCA) model and the simple number it gives for the
shipping/freight sector of the economy. ( I
need more detail and I need it on both a per dollar basis (similar to
what EIO-LCA does, with more detailed breakdown) and a per weight per

Your request seems do-able, and I hope you won't take this comment the
wrong way, but you are asking for a professional-level engineering
evaluation that would cost 50-100 times more than your list price in
the open market.

Please reconsider the scope of what you're asking relative to your
offering price, and see if there's a way to streamline your query.

Best of luck.

There is no answer at this time.

This IS a graduate-student-level question. You could support a hungry
grad student for a term for him to research the question. On the other
hand, try professional chemists' and environmentalists' websites and
see of someone has already researched this (very likely). Try
NewScientist,, etc.
