PREAMBLE

THE PARTIES TO THIS PROTOCOL,

BEING Parties to the Vienna Convention for the Protection of the Ozone Layer,

MINDFUL of their obligation under that Convention to take appropriate measures to protect human health and the environment against adverse effects resulting or likely to result from human activities which modify or are likely to modify the ozone layer,

RECOGNIZING that world-wide emissions of certain substances can significantly deplete and otherwise modify the ozone layer in a manner that is likely to result in adverse effects on human health and the environment,

CONSCIOUS of the potential climatic effects of emissions of these substances,

AWARE that measures taken to protect the ozone layer from depletion should be based on relevant scientific knowledge, taking into account technical and economic considerations,

DETERMINED to protect the ozone layer by taking precautionary measures to control equitably total global emissions of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge, taking into account technical and economic considerations and bearing in mind the developmental needs of developing countries,

ACKNOWLEDGING that special provision is required to meet the needs of developing countries, including the provision of additional financial resources and access to relevant technologies,

BEARING in mind that the magnitude of funds necessary is predictable, and the funds can be
expected to make a substantial difference in the world’s ability to address the scientifically established problem of ozone depletion and its harmful effects,

NOTING the precautionary measures for controlling emissions of certain chlorofluorocarbons that have already been taken at national and regional levels,

CONSIDERING the importance of promoting international co-operation in the research, development and transfer of alternative technologies relating to the control and reduction of emissions of substances that deplete the ozone layer, bearing in mind in particular the needs of
developing countries,

* 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.

CH3Br methyl bromide 0.6

This text contains the latest version of the Montreal Protocol on Substances that Deplete the Ozone Layer, updated to March 2000 to include the cumulative amendments to various articles adopted by the Parties at their Second, Fourth, Ninth and Eleventh Meetings. It includes also the adjustments in levels of production and consumption of the controlled substances listed in annexes A, B, C and E to the Protocol, as decided by the Parties on the basis of assessment made in pursuance of article 6 of the Protocol at the Second, Fourth, Seventh, Ninth and Eleventh Meetings. It should be noted that while adjustments to the Protocol enter into force automatically six months after the date of official notification by the Depositary, each set of amendments is subject to ratification and enters into force and becomes binding for Parties to such amendments only after it has been ratified by a minimum number of Parties.

Separate texts of the adjustments and amendments to the Protocol as agreed by the Parties to the Protocol at meetings in London, Copenhagen, Vienna, Montreal and Beijing are available from either the Depositary, the United Nations Secretary-General, the Ozone Secretariat in UNEP or the Treaties Sections of the Ministries of Foreign Affairs of various Governments.
