If sales fell 6.2% from May to June 2019, this is largely because of a sharp uptick in sales in April, likely an effect of the announced increase in duty of 2 cents per litre for diesel and 1 cent for petrol.
Indeed by June 2019, the sale rate had returned to the same figure for June 2018. Petrol sales saw a smaller spike in April 2019 and by June were slightly above the rate of a year earlier.
Last week, Statec published a report which found that the excise duty increase adds on average €25 to a household’s annual expenditure. It concluded that lowest earning families were more likely to drive diesel vehicles and therefore be slightly more penalised by the increase than higher income households.
