To ask Her Majesty's Government whether flights that begin and end in the United Kingdom but travel to other parts of the world will be categorised as international aviation under article 4 of the draft Climate Change Act 2008 (2020 Target, Credit Limit and Definitions) Order 2009. [HL3908]
A single flight which both begins and ends at aerodromes in the United Kingdom is a domestic flight, regardless of whether it enters airspace outside the United Kingdom. If a flight begins at an aerodrome in the United Kingdom and ends at an aerodrome outside the United Kingdom it is an international flight. Any corresponding return flight would also be an international flight.
Return flights which stop at aerodromes outside the United Kingdom are made up of two separate international flights. Such flights cannot, on any common- sense view, be treated as comprising a single flight which begins and ends at aerodromes in the United Kingdom; the stop at an aerodrome in another part of the world breaks the journey into two flights for the purposes of the definition in Article 4 of the order.
