This paper analyses the role of Renewable Energy Sources (RES) in Spain as a factor to balance the driving force CO2 emissions. To that end, a multi-sectoral analysis based on the Log-Mean Divisia Index Method (LMDI I) was conducted for the 1995-2009 period.Data came from the World Input-Output Database (WIOD) and determined the period under consideration. The paper focuses on the 35 productive sectors included in the WIOD.Major findings show that RES acted in detriment to the drivers of CO2 emissions. This can be stated for the last few years under consideration. The positive trend for the share of RES in Spain's energy matrix together with the negative tendency in the use of fossil fuels leads us to be optimistic.The results are interesting, not only for researchers but also for utility companies and policy-makers. In fact, this paper speaks directly to the authorities of Spain and their political agenda with regard to RES policy.

The aim of this paper is to identify the main drivers of CO 2 emissions in Spain, using an enhanced Structural Decomposition Analysis (SDA) from an extended Input-Output Model, which would allow both the direct and indirect effects of possible drivers to be captured. Six factors are considered; for two of them at wo-level decomposition is conducted. The approach used is a multisectoral one that offers a fine analysis, which is interesting for policy discussion. Data came from the World Input-Output Database
