While this study predicts the impact and demand elasticity for an instantaneous price increase, the researchers believe that any price imposed will likely phased in gradually or done via a cap-and-trade system. "Any price structure for emissions would hopefully have a clear timetable that would allow utilities and consumers to make informed investment decisions," said M. Granger Morgan, Lord Chair Professor in Engineering in the Department of Engineering and Public Policy at Carnegie Mellon. "In addition to the changes in resource allocation by utilities, consumers would pay more attention to their energy consumption or switch to more energy efficient appliances."
In addition, the study supports and expands on prior research about how a CO2 emissions price would spur greater investment by power generators in new, more efficient technologies. "Our findings indicate that significant reductions in CO2 can and would be observed in the near-term, even before more efficient power generation technologies are deployed on a wide scale," said Jay Apt, associate research professor at the Tepper School of Business at Carnegie Mellon and co-author of the study.
The study, titled "Short Run Effects of a Price on Carbon Dioxide
Emissions from U.S. Electric Generators," appeared in the May 1st issue of
Environmental Science & Technology. The research was by Adam Newcomer, a
PhD candidate in the department of Engineering and Public Policy; along
with Professors Apt and Morgan, Professor Lester B. Lave of the Tepper
School of Business at Carnegie Mellon; and Professor Seth Blumsack of Penn
State University. The research was supported by the Carnegie Mellon
Electricity Industry Center, established in August 2001 to work with
industry, government and other stakeholders to address the strategic
problems of the electricity industry, making it more competitive and its
