Diese Studie analysiert die Auswirkungen der Regional Greenhouse Gas Initiative (RGGI), eines Kohlenstoffpreissystems im Nordosten der Vereinigten Staaten, auf CO2 Emissionen. Um den Effekt abzuschätzen werden mehrere ökonometrische Methoden verwendet, einschließlich der Synthetic Control Me- thod. Für den Bundesstaat Maryland ist der geschätzte kausale Effekt eine Reduzierung der CO2-Emissionen um 1,27 Tonnen pro Kopf im Jahr 2019 im Vergleich zu einem Szenario ohne RGGI. Dieses Ergebnis ist robust gegenüber einer Reihe von Placebo-Tests.
This study analyzes the effect of the Regional Greenhouse Gas initiative (RGGI), a carbon pricing system in the northeast of the United States, on CO2 emissions. To estimate the effect, several econometric methods are used, including the synthetic control method. For the state of Maryland, the estimated causal effect is a reduction in CO2 emissions of 1.27 tons per capita in the year 2019 compared to a scenario in the absence of the RGGI. This result is robust to a number of placebo tests.
