There are several categories of flight which are exempt from the EU ETS. These are contained in Annex I of the EU ETS Directive and include activities such as search & rescue, state flights transporting third countries' Heads of State, Head of Government and Government ministers, police flights amongst others.

There are special codes to designate these types of flight which should be inserted into the flight plan which is filed by the operator in order that the flight can be correctly excluded. More information about the types of flight excluded and the associated codes to be inserted in the flight plan can be found in the Annex I Decision1.
