President Obama has no plans to propose a tax on carbon emissions, a White House official said.

“The Administration has not proposed nor is planning to propose a carbon tax,” the official said.



Imposing a tax on fossil energy sources to curb greenhouse gas emissions faces huge political hurdles. But the idea has nonetheless received increased attention of late, especially as policymakers seek ways to address the deficit.



The concept drew fresh buzz this week when an analyst with banking giant HSBC predicted that Obama might pursue a carbon tax.

“A second Obama Administration could also explore the potential for raising revenues from a carbon tax as part of a wider package of measures to avoid the ‘fiscal cliff,’ ” said HSBC’s Nick Robins in a Nov. 7 research note, regarding the pending spending cuts and tax increases set to hit in January if Congress fails to reach a deal to prevent them.



Citigroup’s investment research group also raised the possibility that carbon taxes would surface in fiscal cliff talks.
