Please join us for the Greenspun College of Urban Affairs' College Colloquia Series on December 5th. Dr. Jaewon Lim, associate professor in the School of Public Policy and Leadership, and Dr. DooHwan Won, professor in the Department of Economics at Pusan National University in South Korea and current visiting professor in the School of Public Policy and Leadership, will present, "Impact of the Tailpipe Emission Standard Policy on CO2 Emission: Dynamic Panel Approach Among U.S. States."
According to the U.S. Energy Information Administration (EIA), U.S. carbon dioxide emissions from energy sources hit a 25-year low in 2017. That said, however, the total metric tonnage of CO2 emission from transportation exceeded that from electric power for the first time. Each state in the U.S. has a different set of policies to meet the tailpipe emission standard. In 2004, CARB (California Air Resources Board) approved the nation’s first GHG (Greenhouse Gas) emission standards specifically for cars, with 13 other “CARB states” following suit. The purpose of this talk is to examine CARB’s controversial tailpipe emission policy and its potential conflictual impact between the Trump administration’s EPA and CARB states. Using the panel dataset for 49 U.S. states over a 29-year study period (1987-2015), the estimation results from the proposed dynamic panel data GMM system model (DPD GMM-SYS) clearly indicate the expected effects of three policy-related variables.
