The Regional Greenhouse Gas Initiative (RGGI) is a joint effort by a number of Northeast States to control for regional CO_2 emissions.  The objective is to reduce CO_2 emissions from the power sector 10% below the current level by 2015 using a cap-and-trade program.  The State of Maryland has sponsored an analysis to determine the impacts on Maryland of participating in RGGI.  In particular, this analysis sought to evaluate the competitiveness of the state power sector and as well as the any increases in electricity costs for consumers and CO2 emissions in Maryland. This presentation will summarize the methods and results of that study.(Please visit this website for more information:  http://faculty.ucmerced.edu/ychen/index.html).
