What's in a name? Everything when it comes to a carbon dioxide cap-and-trade programme in the US. Energy industry prognosticators saw US adoption as almost inevitable just two years ago following the election of President Obama. Then opponents dubbed the initiative 'cap-and-tax', a moniker that became a death knell in a political climate wary of raising taxes. Cap-and-trade legislation died with neither a bang nor a whimper; but with a slammed door. Meaningful political debate stopped on the federal level, and the words 'greenhouse gases' apparently ceased to be used in Washington, DC.
