Companies obliged to participate in the European Emissions Trading System (EU ETS) are required to issue certain notifications. They must notify the NEa of certain changes, e.g. to company or contact information. The monitoring plan must also be kept up-to-date. In addition, the NEa may alter the number of free allowances allocated based on these notifications.

The monitoring plan sets out how companies determine their emissions. The NEa must be notified of any changes in monitoring.

Up-to-date monitoring plan

Companies must keep their monitoring plan up-to-date, including the accompanying documentation such as the sampling plan. Any changes that take place within an installation may require the company to alter their monitoring plan. The company must report changes of this type to the NEa, and any significant changes require the NEa's approval (i.e. changes to the actual monitoring methods). No other monitoring notifications require approval – these are categorised as non-significant changes. Companies must also notify the NEa in good time of any temporary deviations from the monitoring plan and of emissions measurements.

Double notifications

Changes affecting the installation's capacity may result in a double notification. One such example is the removal of technical units, in which case companies must issue both a monitoring notification and an allocation notification. Different deadlines and procedures apply to these notification types.

The mandatory notification regulations are set out in the Monitoring and Reporting Regulation (Monitoring en Rapportage Verordening) and the Allowances Trading Regulations (Regeling handel in emissierechten).

Registration of changes by companies

Companies must also maintain an internal overview of implemented changes, which must contain the following information:

  • a transparent description of the change;
  • a justification of the change;
  • the date the NEa was notified of the change;
  • the date the change was approved (if applicable); and
  • the date when the modified monitoring plan was put into practice.

The monitoring plan itself must also include a version history.
