An ex-post evaluation of the effectiveness of the Swiss CO2 levy: Final report Module B

The report analyse the impact of the CO2 levy implemented since 2008. We analyze two main scenarios. First, a historical scenario that includes the CO2 levy and the exemption regimes and replicates the historical development of the Swiss economy and in particular the resulting energy consumptions and CO2 emissions for the period 2008-2013 including a forecast for the year 2014. The second scenario is a counterfactual scenario in which the CO2 levy and exemption regimes are removed. We then compare the results of the two scenarios and thereby evaluate the impacts of the Swiss CO2 levy.
