The Fuel Adjustment Factor (“CAP“) is a monthly revised fuel surcharge indexed to the price of diesel for road transport.

As this official tariff is published with a two-month delay, the surcharge applicable for a given month M corresponds to the tariff of the month M-2.

The road CAP  is based on the index of the National Road Committee (CNR) “professional diesel – base December 2000”, published monthly on the following website: www.cnr.fr.
