The scope of the survey remains the same as for EACEI 2014.
Changes in the sampling design (abandonment of the waste management sector) and correction methods may also affect certain changes.
Note that data from the waste management sector (divisions 38 and 39) were released separately.

The data from the EACEI 2015 survey can be partly supplemented by ECEI-PE 2014 by being vigilant as to the differences in scope: ECEI-PE, in addition to the one-year lag, surveys establishments with 1 to 19 employees and focuses only on a limited number of energies.
