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.

Holy See

05-05-2008

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).

Portugal

21-10-1999

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.

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.
