CNR road passenger transport commercial diesel index intends to observe the evolution of the diesel cost used as fuel by vehicles assigned to the public transport of passengers by road, excluding VAT, taking into account various refueling methods (pump and storage tank) and the partial refund of the French Excise Duty on Commercial Diesel (TICPE) valid for each quarter. Base 100 = December 2019

CNR road passenger transport commercial diesel index is available online on the penultimate day of the current month (excluding Sundays and public holidays) at midnight. It includes weekly statements of diesel prices at the pump (DGEC source) as well as bi-monthly statements of diesel prices at the tank (CNR source) available at the date of publication. The other statements of the current month communicated after this date are considered in the index of the following month. Thus, over the year, the CNR index takes into account all the DGEC weekly prices statements of diesel at the pump. These methodological adjustments implemented in April 2022 do not lead to a beak in the chronological index series.
