In April 2015 excise duties on petroleum products decreased again; the difference between the indices was noticeable in the group transport, where the HICP was lower than the HICP-CT (by 0.3 p.p.).
Tudi aprila so se trošarine na naftne derivate nekoliko znižale; mesečna indeksa sta se razlikovala le v skupini prevoz; HICŽP je bil za 0,3 odstotne točke nižji od HICŽP-CT.
