price of carbon
 n.— «Even if options are available that are low cost and represent additional effort beyond the AEO base case, these options may have relatively little bearing on the price of carbon in a competitive environment. It is the cost of the last ton reduced, wherever in the world that occurs, that will set the price in a competitive market for carbon emissions reductions.» —“Kyoto Protocol’s Impact On U.S. Energy” by Jay E. Hakes Congressional Testimony by Federal Document Clearing House Oct. 9, 1998. (source: Double-Tongued Dictionary)
