Article 4
1. Any Parties included in Annex I that have agreed to jointly
fulfil their commitments under Article 3 shall be deemed to have met
those commitments provided that their total combined aggregate
anthropogenic carbon dioxide equivalent emissions of the greenhouse
gases listed in Annex A do not exceed their assigned amounts
calculated pursuant to their quantified emission limitation and
reduction commitments inscribed in Annex B and in accordance with the
provisions of Article 3. The respective emission level allocated to
each of the Parties to the agreement shall be set out in that
agreement.
2. The Parties to any such agreement shall notify the secretariat
of the terms of the
agreement on the date of deposit of their instruments of
ratification, acceptance, approval or accession. The secretariat
shall in turn inform the Parties and signatories to the Convention of
the terms of the agreement.
3. The agreement shall remain in operation for the duration of the
commitment period specified in Article 3, paragraph 7.
4. If Parties acting jointly do so in the framework of, and
together with, a regional
economic integration organization, any alteration in the
composition of the organization after adoption of this Protocol shall
not affect existing commitments under this Protocol. Any alteration
in the composition of the organization shall only apply for the
purposes of those commitments under Article 3 that are adopted
subsequent to that revision.
5. In the event of failure by the Parties to such an agreement to
achieve their total
combined level of emission reductions, each Party to such an
agreement shall be responsible for its own level of emissions set out
in the agreement.
6. If Parties acting jointly do so in the framework of, and
together with, a regional
economic integration organization which is itself a Party to this
Protocol, each member State of that regional economic integration
organization individually, and together with the regional economic
integration organization acting in accordance with Article 23, shall,
in the event of failure to achieve the total combined level of
emission reductions, be responsible for its level of emissions as
notified in accordance with this Article.
