That, consistent with the constitutional status of Tokelau and taking into account the commitment of the Government of New Zealand to the development of self-government for Tokelau through an act of self-determination under the Charter of the United Nations, this Accession shall not extend to Tokelau unless and until a Declaration to this effect is lodged by the Government of New Zealand with the Depositary on the basis of appropriate consultation with that territory.

United States of America

The United States of America understands that the Protocol of 1997 does not, as a matter of international law, prohibit Parties from imposing, as a condition of entry into their ports or internal waters, more stringent emission standards or fuel oil requirements than those identified in the Protocol.
The United States of America understands that Regulation 15 applies only to safety aspects associated with the operation of vapour emission control systems that may be applied during cargo transfer operations between a tanker and port-side facilities and to the requirements specified in Regulation 15 for notification to the International Maritime Organization of port State regulation of such systems.
The United States of America notes that at the time of adoption of the Protocol of 1997, the NOx emission control limits contained in Regulation 13 were those agreed as being achievable by January 1 2000, on new marine diesel engines, and further notes that Regulation 13(3)(b) contemplated that new technology would become available to reduce on-board NOx emissions below those limits. As such improved technology is now available, the United States expresses its support for an amendment to Annex VI that would, on an urgent basis, revise the agreed NOx emission control limits contained in Regulation 13 in keeping with new technological developments.
