How Strong Might Be a Carbon Tax on Electricity Consumption to Reach Spanish H2020 Targets

This chapter evaluates the cumulative impact (2014–2020) that a tax on electricity consumption would have on it consumption in Spain. Changes in electricity consumption are caused by increasing purchasing prices due to tax. Impact on revenues and CO2 emissions are also assessed through a model price. Tax reform is inspired on final report presented by a Group of Experts commissioned by the Government of Spain in 2014. The evaluation has been performed by considering two scenarios, without (Scenario 1) and with tax recycling between the new tax and employer-paid Social Security benefits or with tax using a price stability tool (Scenario 2). Data comes from the Social Accounting Matrix at purchase prices for Spain in 2006 (SAMESP06). Right rates of a carbon tax designed on electricity consumption would range between 6.24% and 5.52% to reach the total target.
