Discussions on carbon footprints continue, and consumers are starting to tally their total carbon footprint. A recent article in the Wall Street Journal looked at six different products — including milk — and the carbon footprint of each.

For example, a fleece jacket has a carbon footprint of approximately 66 pounds of carbon dioxide; laundry detergent 31 pounds; boots 121 pounds; cars 97,000 pounds; beer 7 pounds — and milk, 7.2 pounds.
              
The challenging part when it comes to carbon-foot-printing is that it’s almost impossible to compare goods, as different companies count their carbon footprints differently.

Studies are under way to look closer at the carbon footprint of milk, but each study comes up with a different number, because each study counts things differently.
