Which ton is used for the carbon footprint in the US? Short ton or metric ton? I saw that the recent Car and Driver magazine has been reporting pounds/mile CO2 emissions figures for the cars they review, so I can only assume when discussing tons of carbon produced by whatever entities, we're using short tons. Correct? This reminds me of some incident a year or two ago when the White House declared that they saved a bunch of money by paying for their carbon footprint by the short ton rather than the metric ton.
