Abstract: This paper analyses the environmental
efficiency of a sample of chemical firms located in Italy and Germany, which
are included in the European Pollution Emission and Transfer Register (E-PRTR).
The adoption of a common set of standards can open important way to compare
economical and ecological performances of firms which must follow the same
formal rule, but operating in different countries. The Directional Distance
Function (DDF) approach is here applied to obtain global efficiency scores able
to consider pollution in computations: emissions generally increase between
2004 and 2007, with a worse performance of Italian firms. Eco-efficiency indicators
partially slim down that evidence considering both turnover and input usage,
underlining a reduction of average inefficiencies over time.
From a dynamic viewpoint empirical findings shows a most
favourable trends in environmental TFP growth for German firms.
