Declarations
(Unless otherwise indicated, the declarations were made
upon ratification, acceptance, approval, accession or succession.)
Bahrain 8

Holy See

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).”
Japan

Declaration:

       It is hereby declared that the Government of Japan accepts the Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, in accordance with the provisions of article 9 of the Vienna Convention for the Protection of the Ozone Layer.
End Note
1On 15 February 1994, the Secretary-General received from the Government of Portugal a notification to the effect that it shall extend the Amendment to Macau.
Subsequently, the Secretary-General received the following communications on the dates indicated hereinafter:
Portugal (21 October 1999):
“In accordance with the Joint Declaration of the Government of the Portuguese Republic and the Government of the People's Republic of China on the Question of Macau signed on 13 April 1987, the Portuguese Republic will continue to have international responsibility for Macau until 19 December 1999 and from that date onwards the People's Republic of China will resume the exercise of sovereignty over Macau with effect from 20 December 1999.
From 20 December 1999 onwards the Portuguese Republic will cease to be responsible for the international rights and obligations arising from the application of the Convention to Macau."
China (19 October 1999):
In accordance with the Joint Declaration of the Government of the People's Republic of China and the Government of the Republic of Portugal on the Question of Macau (hereinafter referred to as the Joint Declaration), the Government of the People's Republic of China will resume the exercise of sovereignty over Macau with effect from 20 December 1999.  Macau will, from that date, become a Special Administrative Region of the People's Republic of China and will enjoy a high degree of autonomy, except in foreign and defense affairs which are the responsibilities of the Central People's Government of the People's Republic of China.
In this connection, [the Government of the People's Republic of China informs the Secretary-General of the following:]
The Vienna Convention for the Protection of the Ozone Layer, which the Government of the People's Republic of China deposited the instrument of accession on 11 September 1989, as well as the Montreal Protocol on Substances that Deplete the Ozone Layer of 16 September 1987 and tAmendment to the Montreal Protocol on Substances that Deplete the Ozone Layer of 29 June 1990 (hereinafter referred to as the "Convention, the Protocol and the Amendment"), will apply to the Macau Special Administrative Region with effect from 20 December 1999.  The Government of the People's Republic of China also wishes to make the following declaration:
Provisions of Article 5 of the Montreal Protocol on Substances that Deplete the Ozone Layer of 16 September 1987 will not be applied to the Macau Special Administrative Region, and provisions of paragraph 1 of Article 5 of the Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer of 29 June 1990 will not be applied to the Macau Special Administrative Region.
In reference to the communication made on 19 October 1999, the Government of China furthermore informs the Secretary-General of the following:
The Government of the People's Republic of China will assume responsibility for the international rights and obligations arising from the application of the Convention, the Protocol and the Amendment to the Macau Special Administrative Region.
The above-mentioned declaration is solely to make the provisions of the Protocol that had previously applied to Macau continue to so apply to the Macau Special Administrative Region.  The declaration is not purported to modify the obligations previously undertaken by Macau under the Protocol and is fully consistent with the objectives and purposes of the Protocol.  In fact, the Chinese Government had made a statement of the same nature in the note of 6 June 1997 to the Secretary-General of the United Nations concerning the continuing application of the Protocol to the Hong Kong Special Administrative Region.  The past two years and a half since Hong Kong's return to China saw a clear and full understanding on the part of the Parties to the Protocol of the approach adopted by the Chinese Government.
2On 6 and 10 June 1997, the Secretary-General received communications concerning the status of Hong Kong from the Governments of the United Kingdom and China (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 with the reservation made by China will also apply to the Hong Kong Special Administrative Region.
3Decision reserved as to the application to the Faroe Islands.

On 24 October 2007, the Secretary-General received from the Government of Denmark a communication that it shall extend the Amendment to the Faroe Islands.
4See note 1 under "Montenegro" in the "Historical Information" section in the front matter of this volume.
5For the Kingdom in Europe.

In a communication received on 16 March 1992, the Government of the Netherlands notified the Secretary-General that "the Kingdom of the Netherlands accepts the Amendment . . . for Aruba, and [declares] that the provisions so accepted shall be observed in their entirety."
6See also note 1 under “New Zealand” regarding Tokelau in the “Historical Information” section in the front matter of this volume.
7In respect of the United Kingdom of Great Britain and Northern Ireland and Gibraltar.

Subsequently, the Government of the United Kingdom of Great Britain and Northern Ireland notified the Secretary-General that the amendment shall extend to the following territories on the dates indicated hereinafter:

Date of the notification:Territorial application:
8 September 1993Hong Kong, British Antarctic Territory and the Bailiwick of Guernsey

25 February 2021Isle of Man


On 17 April 2015, the Secretary-General received from the Government of Spain the following communication 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 certain international treaties (2007)”, which were agreed to 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 to Gibraltar of the present Amendment 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.
8On 8 July 2021, the Government of Bahrain notified the Secretary-General of its withdrawal of the following declaration made upon acceptance :

“The acceptance by the State of Bahrain of the said Amendments shall in no way constitute recognition of Israel or be a cause for the establishment of any relations of any kind therewith.”
