    Message to the Senate Transmitting the Amendment to the Montreal
    Protocol on Ozone-Depleting Substances
    July 20, 1993

    To the Senate of the United States:
        I transmit herewith, for the advice and consent of the Senate to
    ratification, the Amendment to the Montreal Protocol on Substances That
    Deplete the Ozone Layer (``Montreal Protocol''), adopted at Copenhagen
    on November 23-25, 1992, by the Fourth Meeting of the Parties to the
    Montreal Protocol. I am also enclosing, for the information of the
    Senate: the adjustments, also adopted November 23-25, 1992, that
    accelerate the respective phaseout schedules for substances already
    controlled under the Protocol (chlorofluorocarbons (CFCs), halons, other
    fully halogenated CFCs, methyl chloroform, and carbon tetrachloride);
    and the report of the Department of State.
        The principal feature of the Amendment that was negotiated under the
    auspices of the United Nations Environment Program (UNEP), is the
    addition of new controlled substances, namely hydrochlorofluorocarbons
    (HCFCs), hydrobromofluorocarbons (HBFCs), and methyl bromide. The
    Amendment, coupled with the adjustments, will constitute a major step
    forward in protecting public health and the environment from potential
    adverse effects of stratospheric ozone depletion.
        The Amendment will enter into force on January 1, 1994, provided
    that 20 Parties to the Montreal Protocol have deposited their
    instruments of ratification, acceptance, or approval. Early ratification
    by the United States is important to demonstrate to the rest of the
    world our commitment to protection and preservation of the stratospheric
    ozone layer and will encourage the wide participation necessary for full
    realization of the Amendment's goals.
        I recommend that the Senate give early and favorable consideration
    to the Amendment and give its advice and consent to ratification.

                                                          William J. Clinton

    The White House,
