Companies may not see standardized global pricing for carbon emissions for 10 or 15 years, said analysts at an industry meeting in Copenhagen.
The analysts say too many governments are too slow to adopt regulations and standards, and that is enough to thwart standardization, according to a Reuters article.
The European Union has stated it would like to see all OECD nations adopt carbon trading schemes within their own countries by 2013. The EU would like to see those linked by 2015, and have global emissions trading standards linked by 2020.
Trevor Sikorski, an analyst at Barclays Capital, said he thought it was "incredibly ambitious" for the EU to expect to link to U.S. standards by 2015.
The Environmental Protection Agency has proposed national reporting of major sources of carbon emissions.
The Voluntary Carbon Standards Association recently added a global registry to its carbon-trading system, but plans to link carbon trading registries in multiple nations are on hold.
