Dear fuel, new price increases: a full tank costs up to 7 euros more in a month

According to Codacons, in a month a full tank has increased by up to 7 euros, with more marked increases on the motorway network for both petrol and diesel. The association warns that the escalation of price lists is weighing on family budgets and calls for a strengthening of the excise duty cut, to be extended to petrol

Codacons analysis

Compared to August 15, petrol on the ordinary network increased by 12.9 cents, equal to an increase of 6.45 euros per tank. On the motorway the growth is 14.3 cents, with an increase of 7.15 euros. For diesel, the monthly increase is 13.9 cents on the ordinary network (+7 euros at full tank) and 14.5 cents on the motorway (+7.25 euros).

The requests of the consumer association

Codacons warns that the "non-stop escalation of price lists at the pump risks causing a tsunami effect on families, because it aggravates both the direct costs linked to supplies and the indirect ones linked to prices and tariffs in a multitude of sectors". The association believes that "selective interventions and bonuses linked to income do not appear to be adequate solutions because they would only help a small part of families, leaving the community of citizens at the mercy of astronomical price increases. Faced with the new data on fuels - concludes the consumers' association - a further effort is needed to strengthen the cut in excise duties and also extend it to petrol, which on the motorway has already exceeded the historical record reached in 2022".
