Declarations

Vatican City State
Declaration:“In acceding to the Vienna Convention on the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer, as well as its four Amendments: London (1990), Copenhagen (1992), Montreal (1997) and Beijing (1999), the Holy See desires to encourage the entire International Community to be resolute in promoting authentic cooperation between politics, science and economics. Such cooperation, as has been shown in the case of the ozone regime, can achieve important outcomes, which make it simultaneously possible to safeguard creation, to promote integral human development and to care for the common good, in a spirit of responsible solidarity and with profound positive repercussions for present and future generations.In conformity with its own nature and with the particular character of Vatican City State, the Holy See, by means of the solemn act of accession, intends to give its own moral support to the commitment of States to the correct and effective implementation of the Treaties in question and to the attaining of the mentioned objectives. To this end, it expresses the wish that by recognizing ‘the signs of [an economic growth] that has not always been able to protect the delicate balances of nature’ (Homily of Pope Benedict XVI at Loreto, 2 September 2007), all actors will intensify the aforesaid cooperation and strengthen ‘the alliance between man and the environment, which must mirror the creative love of God, from whom we come and to whom we are bound’(Benedict XVI, After the Angelus, 16 September 2007).”

Subsequently, in a communication received on 30 October 1995, the Government of the United Kingdom of Great Britain and Northern Ireland notified the Secretary-General that the amendment shall apply to the British Virgin Islands and Hong Kong, for whose international relations the Government of the United Kingdom is responsible.

In this regard, the Secretary-General received, on 6 and 10 June 1999, communications concerning the status of Hong Kong from China and the United Kingdom (see also note 2 under “China” and note 2 under “United Kingdom of Great Britain and Northern Ireland” regarding Hong Kong in the “Historical Information” section in the front matter of this volume). Upon resuming the exercise of sovereignty over Hong Kong, China notified the Secretary-General that the Convention will also apply to the Hong Kong Special Administrative Region.

- On 5 August 2014 the Government of the United Kingdom of Great Britain and Northern Ireland notified the Secretary-General that the Amendment would extend to the territory of Gibraltar as follows:

“… the Government of the United Kingdom of Great Britain and Northern Ireland wishes the United Kingdom’s Ratification of the [Amendment] be extended to the territory of Gibraltar for whose international relations the United Kingdom is responsible.

The Government of the United Kingdom of Great Britain and Northern Ireland considers the extension of the [Amendment] to the territory of Gibraltar to enter into force on the day of receipt of this notification by [the depositary] for deposit… ”

On 17 April 2015, the Secretary-General received from the Government of Spain the followingcommunication relating to the territorial application by the United Kingdom of Great Britain and Northern Ireland to Gibraltar:

1. Gibraltar is a Non-Self-Governing Territory for whose international relations the Government of the United Kingdom is responsible and which is subject to a process of decolonization in accordance with the relevant decisions and resolutions of the General Assembly.

2. The authorities of Gibraltar are local in character, and exercise competences exclusively over internal affairs that originate in and are based on the powers allocated to and conferred on them by the United Kingdom, in accordance with its domestic legislation and in its capacity as the sovereign State upon which depends the said Non-Self-Governing Territory.

3. Consequently, any involvement by the Gibraltarian authorities in the implementation of this Amendment shall be understood to take place exclusively within the framework of the internal affairs of Gibraltar and shall not be considered to affect in any way the content of the two preceding paragraphs.

4. The procedure envisaged in the “Arrangements relating to Gibraltar authorities in the context of Mixed Agreements (2007)” which was agreed by Spain and the United Kingdom on 19 December 2007 together with "Agreed Arrangements relating to Gibraltar authorities in the context of European Union and European Community Instruments and Related Treaties" of 19 April 2000, applies to the present Amendment.

5. The application of the present Amendment to Gibraltar cannot be interpreted as recognition of any rights or situations involving matters not included in Article 10 of the Treaty of Utrecht of 13 July 1713, signed by the crowns of Spain and Great Britain.

On 25 February 2021, the Government of the United Kingdom of Great Britain and Northern Ireland notified the Secretary-General that the Amendment would extend to the territory of the Isle of Man as follows:

“... the Government of the United Kingdom of Great Britain and Northern Ireland hereby extends the application of the United Kingdom’s ratification of the… Copenhagen…[Amendment] to the Montreal Protocol to the territory of the Isle of Man for the international relations of which the United Kingdom is responsible.

The Government of the United Kingdom of Great Britain and Northern Ireland considers the extension of the… Copenhagen… [Amendment] to the Montreal Protocol to the territory of the Isle of Man to be effective on the day of receipt of this notification...”
