However, if we consider that France indicates that the number of member vessels is 2385, including a considerable proportion of coastal vessels of less than 12 metres, whose annual fuel consumption is closer to 200 tonnes that the 480 tonnes used in the above calculation, it is probable that the actual amount is significantly less.
Or, si l’on considère que la France indique un chiffre de navires adhérents de 2385, parmi lesquels une proportion non négligeable de navires côtiers de moins de 12 mètres, dont la consommation annuelle de carburant est plus proche de 200 tonnes que des 480 retenues pour le calcul ci-dessus, il est probable que le montant réel est significativement moindre.
