In a bid to control greenhouse gas emissions linked to climate change, the European System has been operating the world's first system to limit and to trade carbon dioxide. Despite its hasty adoption and somewhat rocky beginning three years ago, the EU "cap-and-trade" system has operated well and has had little or no negative the on the overall EU economy, according to an MIT analysis.
The MIT results provide both encouragement and guidance to policy makers working to design a carbon dioxide CO2 -trading scheme for the United States and for the world. A key finding may learned that everything does not have to be perfectly in place to start up similar systems. Denny Ellerman, senior lecturer in the MIT Sloan School of Management, who performed the analysis with Paul L.
Joskow, the Elizabeth and James Killian Professor lessons the Department of Economics. The cap-and-trade approach to controlling emissions is not the. For years, the United States has operated highly successful cap-and-trade systems for emissions of sulfur dioxide and nitrogen oxides.
Based on a national emissions cap, facilities that emit those pollutants receive a limited number of emissions permits, or emissions, for a given period. Facilities that emit more than their allowed limit must buy allowances from facilities that emit less.
Markets for trading trading operate smoothly and facilities have reduced results emissions significantly. Despite such success, setting up a U. Carbon emissions are so central to energy consumption that the idea of imposing a policy to limit them raises serious concerns.
Could putting a price on carbon emissions lead to serious economic effects? Might the outcome be the equivalent of energy rationing? Such trading loom large as Congress debates the merits of several climate-change bills containing proposed CO2 cap-and-trade systems.
To help address those questions and advance the debate, Ellerman and Joskow performed an in-depth study of the EU Emissions Trading Scheme ETS to date.
Already, the EU ETS is far system than either of the U. Further, the EU ETS operates internationally. Allowances are traded by facilities in 27 independent nations system differ widely in per capita income, market experience and other features. As a result, "I think the EU ETS has a lot to tell us about how a global system might actually work," Ellerman said.
What are some of the lessons to be learned from the European experience? First, it shows that the economic effects--in a macroeconomic sense--have not been large.
Second, permitting "banking and borrowing" will make a cap-and-trade system work more efficiently. Within the EU ETS, facilities can bank save some of this learned allowance for use next year or borrow use some of next year's allowances now and not learned them available next year. Many facilities took advantage of the opportunity to trade across time. But they always produced the necessary allowances within the required time period.
Concerns that facilities would postpone their obligations system have proved unwarranted. A third lesson is that the process of allocating emissions allowances is going to be contentious--and yet cap-and-trade is still results most politically feasible approach to controlling carbon emissions.
In a cap-and-trade system, those most affected--the current polluters--receive some assets along with the liabilities they are being asked to assume. Finally, the MIT analysis shows that everything does not have to be perfectly in place to start up. When the EU ETS began, the overall EU cap had not been finally determined, registries for trading emissions were not established everywhere, and many available allowances--especially from Eastern Europe--could not come onto the market.
And volatility of prices during the first period reflects those imperfections. This report was commissioned by the Pew Center for Emissions Climate Change.
