An Economic Assessment of Connecticut's Nitrogen Credit Exchange Program

Project Started 2014

Zinnia Mukherjee Research

Professor Zinnia Mukherjee's research addresses the problem of understanding the economic and environmental impact of Connecticut’s Nitrogen Credit Exchange Program (CT NCT program) – the nation’s most significant water quality trading program so far. 

This unique, incentive-based trading program has been designed by the CT Department of Energy and Environmental Protection (CT DEEP) and the U.S. Environmental Protection Agency (EPA) to address water pollution in the Long Island Sound. The CT NCT program started in 2002 and was renewed by Connecticut's governor in 2015. 

Mukherjee’s aim is to do an economic analysis to evaluate the effectiveness of the program by assessing its impact on the water quality in the sound and compare this program with the other water quality improvement programs previously used or currently in use by the United States.
