Since the beginning of the Industrial Revolution, emissions of CO2 due to human activities have led to a marked increase in atmospheric concentrations of long-lived gases, leading to a worrisome global warming. In recent years, with a view to contribute to design suitable policies to control those emissions, numerous environmental studies have analyzed the trends in gas emissions and their main drivers. In this paper we explore in detail the trend of carbonization as a driving force for CO2 emissions in the EU Member States. By implementing the so-called Sato-Vartia logarithmic mean Divisia index (LMDI-II) method, we factorize the emission change in the EU for the 2000-2010 period. Results point to the carbonization effect, along with the intensity effect, as one of the most relevant factors. Then, relying on the so-called attribution analysis (Choi and Ang, 2012; Fernández González et al., 2013) we present a new theoretical framework that enables attribution of percent changes in the carbonization index to individual EU Member States. This deeper study shows the strong concentration of this reducing influence in some big economies, with Germany, the United Kingdom, France and Italy contributing by more than 50%. Furthermore, adding Spain and Poland, the total contribution exceeds 75% of total change. Findings in this paper suggest that efforts should focus on strategies aiming at encouraging innovation, adaptation to more efficient and environmentally friendly technologies, research for higher quality energies, lower carbon fuel substitution and instalment of abatement technologies like carbon capture and storage.
