ÉK: Proposal for a 
COUNCIL DECISION 
concerning the conclusion of the amendment to the Montreal Protocol 
on substances that deplete the ozone layer as adopted in 
November 1992 In Copenhagen by the Parties to the Protocol 
(presented by the Commission)

EXPLANATORY MEMORANDUM 
1. The Community concluded the Vienna Convention for the Protection of 
the Ozone Layer and the Montreal Protocol on Substances that 
Deplete the Ozone Layer through the Council Decision 88/540CEEC) of 
14 October 1988 (1). The Community also concluded the amendment to 
the Montreal Protocol as adopted in London in 1990 through the 
Council Decision 91/690(EEC) of 12 December 1991 (2). 
2. The Scientific Evaluation Group of the United Nations Environment 
Programme (UNEP) found the hole in the ozone layer in the Antarctic 
in 1991 to be as deep and extensive as the holes observed in 1987, 
1989 and 1990. For the first time, observations in the Antarctic 
confirmed that the loss of ozone coincides with an increase in 
ultraviolet radiation at ground level. Moreover, the stratospheric 
ozone layer is being depleted more rapidly than expected and ozone 
losses are now being observed over densely populated areas of 
Europe and North America. The satellite-mounted TOMS spectrometer 
measured ozone losses from December to March of - 5.6% ± 3.5% per 
decade over the period 1979 to 1991 at a latitude of 45" North. The 
concentration of chlorine in the stratosphere is expected to 
increase from the present level of 3.3 ppbv (parts per billion 
volume) to 4.1 ppbv in the year 2000. This increase will occur even 
if all the Parties apply the Protocol as amended in 1990. 
3. In the light of this scientific evidence, the Fifth Action 
Programme underlines the necessity to further accelerate the world 
wide phase down of ozone depleting substances and calls on all 
Parties to the Protocol to adopt stricter control measures than 
those decided in 1990 The Fifth Action Programme also refers to the 
progressive control measures the Community has adopted beyond those 
foreseen by the ProtocolO), 
4. On the basis of the negotiating directives adopted by the Council 
(4), the Commission, in collaboration with the Member States, 
participated in the negotiations leading to the second amendment 
to the Protocol in November 1992 in Copenhagen. The Commission 
proposal for these negotiating directives have taken into account 
the results of prior consultations with industry. 
5. The outcome of the negotiations corresponds largely to the 
positions defended by the Community and the Member States: The 
Parties to the Protocol have decided in Copenhagen, inter alia, to 
strengthen existing controls on chlorofluorocarbons, halons, 
carbon tetrachloride and 1 ,1 ,1-trichloroethane, and to extent the 
controls to methyl bromide, hydrobromofluorocarbons and 
hydroch lorof luorocarbons. All these substances will be banned on a 
worldwide basis by 1 January 1996 except hydrochlorofluorocarbons, 
which are temporarily needed to phase out the other substances, 
and methyl bromide, on which there are ongoing investigations.

6. The ratification of the Copenhagen agreement by the Community will 
not in itself incur any costs within the Community. The internal 
implementation of this second amendment to the Protocol is done 
through Regulation (EEC) No 3952/92 (5), as regards the phase down 
of chlorofluorocarbons, halons, carbon tetrachloride and 1,1,1-
trichloroethane, and through a new Regulation to be proposed by the 
Commission early in 1993, as regards the control on methyl bromide, 
hydrobromofluorocarbons and hydrochlorofluorocarbons. 
7. The Community has participated as a major Party to the Protocol in 
all international negotiations in this field since the beginning in 
the mid '80s and acquired a leadership position in the ozone layer 
protection. It is therefore essential that the Community ratify 
this amendment as soon as possible in order to maintain this 
leadership position through a single strong position vis-à-vis its 
key negotiation partners, like the US, Japan, the Russian 
Federation and developing countries. 
8. The Commission Proposal for a Council Decision concerning the 
conclusion of the second amendment to the Montreal Protocol is 
based on Article 130s, Just as in 1990 the Commission Proposal for 
the ratification of the first amendment, since the Protocol is an 
environmental agreement aiming at restricting the production and 
the consumption of ozone depleting substances. Article 113 has been 
added as a joint legal basis in so far as the Montreal Protocol 
includes trade provisions, which are to be applied to non-
signatories of the Protocol. The proposed legal basis is without 
prejudice to the question of what is the appropriate legal basis 
for the Community Regulation for the implementation of the second 
amendment of the Protocol.

©f 
concerning the conclusion of the amendment to the Montreal Protoco 
on substances that deplete the ozone layer as adopted in 
November 1992 in Copenhagen by the Parties to the Protocol 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European Economic Community, 
and in particular Article 130S and 113 thereof, 
Having regard to the Proposal from the Commission, 
Having regard to the opinion of the European Parliament, 
Having regard to the opinion of the Economic and Social Committee, 
Whereas it is established that continued emissions of 
chlorofluorocarbons, halons, carbon tetrachloride, 1,1,1-trichloroethane, 
methyl bromide and hydrobromofluorocarbons at current levels cause 
significant damage to the ozone layer; whereas there is an international 
consensus that significant reductions in both production and consumption 
of such substances are necessary; 
Whereas hydrochlorofluorocarbons have a much lower ozone depleting 
potential than the above substances and are in certain applications 
substitutes for them, but have to be used in a careful manner because of 
their impact on the ozone layer-, 
Whereas the Community together with all of its Member States have signed 
the Vienna Convention for the protection of the ozone layer, hereinafter 
referred as the 'Vienna Convention'; 
Whereas a Protocol supplementary to the Vienna Convention, the Montreal 
Protocol on substances that deplete the ozone layer, hereinafter referred 
to as the 'Montreal Protocol', was negotiated and adopted on 16 September 
1987; whereas the Protocol has been signed by the Community and by a I I of 
its Member States; whereas a first amendment to the Protocol was adopted 
on 29 June 1990 in London; 
Whereas the Community, in view of the responsibilities for the 
environment and trade, has approved, by Decision 88/540/EEC^3) the 
Vienna Convention and the Montreal Protocol, and by Decision 91/690 EEC 
the first amendment to the Protocol; 
(3) O.J. L 297, 31.1©.1«*8, p. 8 
Whereas the most recent scientific evidence indicates that for the 
adequate protection of the ozone layer a higher degree of control of 
chlorofluorocarbons, halons, carbon tetrachloride and 1,1,1-
trichloroethane is required than that provided by the Montreal Protocol 
as amended In 1990; whereas the same evidence indicates that additional 
controls should be placed on methyl bromide, hydrobromofluorocarbons and 
hydrochlorofIuorocarbons; 
Whereas a second amendment and adjustments to the Montreal Protocol 
implementing these controls have been adopted in Copenhagen in November 
1992 and only the amendment needs to be approved; 
Whereas it is necessary for the protection, promotion and improvement of 
the environment to bring into force the second amendment to the Montreal 
Protocol, which is based on the principle of preventive action to avoid 
further damage to the ozone layer and on the scientific and technical 
data which were available at the time of its adoption; 
Whereas, to that end, the Community must approve this second amendment. 
Whereas it Is, in particular, necessary for the Community and all Member 
States to approve the second amendment to the Montreal Protocol because 
some of its provisions can be carried out only if the Community and all 
its Member States approve it; 
Whereas in order for all the obligations under the second amendment to be 
appropriately carried out, it is necessary that all Member States should 
also approve i t; 
Whereas this amendment has to be ratified by at least twenty Parties to 
the Protocol for its timely entry into force on 1 January 1994, all 
Member States should conclude as rapidly as possible their procedures for 
ratification of the second amendment, with a view to permit the deposit, 
as far as possible simultaneously and in any case before the above date, 
of the instruments of approval, acceptance or ratification by the 
Community and the Member States, 
HAS ADOPTED THIS DECISION: 
Art icle 1 
The second amendment to the Montreal Protocol on substances that deplete 
the ozone layer as adopted in Copenhagen is hereby approved on behalf of 
the Community. 
The text of this amendment appears as an Annex to this Decision.

Article 2 
The President of the Council shall deposit the act of approval of this 
second amendment on behalf of the Community with the Secretary General of 
the United Nations in accordance with Article 13 of the Vienna 
Convention, as read in conjunction with Article 3 of the second amendment 
to the Montreal Protocol. 
Art icle 3 
Member States shall take the necessary steps to permit the deposit, as 
far as possible simultaneously, before 30 November 1993 of the 
instruments of ratification, acceptance or approval of the second 
amendment to the Montreal Protocol by the Community and the Member 
States. 
Member States will inform the Commission, before 31 October 1993 of their 
decision to ratify or of the prospective date of final ization of their 
ratification procedures. The Commission, in cooperation with Member 
States, shall arrange a date for the simultaneous deposit of the 
instruments which shall in any case be before 31 December 1993.

* Where a range of ODPs is indicated, the highest value in that range 
shall be used for the purposes of the Protocol. The ODPs listed as a single 
value have been determined from calculations based on laboratory 
measurements. Those listed as a range are based on estimates and are less 
certain The range pertains to an isomeric group. The upper value is the 
estimate of the ODP of the isomer with the highest ODP, and the lower value 
is the estimate of the ODP of the isomer with the lowest ODP. 
** Identifies the most commercially viable substances with ODP values 
listed against them to be used for the purposes of the Protocol.
