AssoEsco has entrusted Elemens with a study in order to understand what worked and what did not in the field of energy efficiency in Italy. This study showed that the industrial sector produced fewer results due to a malfunction of the energy efficiency certificates; on the contrary, tax deductions brought good results, although not directly to the ESCOs, but to the final consumer. For this reason, ESCOs will ask that this incentive be extended for their benefit too.
