After submitting your quarterly data

  • The ILT checks the delivery data against BDNs on board seagoing vessels.
  • The ILT passes on the delivery data to the Nederlandse Emmisieautoriteit, NEa (Dutch Emissions Authority).
  • The NEa determines your brandstoftransitieverplichting (fuel transition requirement) and informs you of this.
  • The ILT stores the data for at least 36 months.
