(a) Each of these Parties shall adopt national
1
policies
and take corresponding measures on the mitigation of
climate change, by limiting its anthropogenic
emissions of greenhouse gases and protecting and
enhancing its greenhouse gas sinks and reservoirs.
These policies and measures will demonstrate that
developed countries are taking the lead in modifying
longer-term trends in anthropogenic emissions
consistent with the objective of the Convention,
recognizing that the return by the end of the
present decade to earlier levels of anthropogenic
emissions of carbon dioxide and other greenhouse
gases not controlled by the Montreal Protocol would
contribute to such modification, and taking into
account the differences in these Parties' starting
points and approaches, economic structures and
resource bases, the need to maintain strong and
sustainable economic growth, available technologies
and other individual circumstances, as well as the
need for equitable and appropriate contributions by
each of these Parties to the global effort regarding
that objective. These Parties may implement such
policies and measures jointly with other Parties and
may assist other Parties in contributing to the
achievement of the objective of the Convention and,
in particular, that of this subparagraph;
(b) In order to promote progress to this end, each of
these Parties shall communicate, within six months
of the entry into force of the Convention for it and
periodically thereafter, and in accordance with
Article 12, detailed information on its policies and
measures referred to in subparagraph (a) above, as
well as on its resulting projected anthropogenic
emissions by sources and removals by sinks of
greenhouse gases not controlled by the Montreal
Protocol for the period referred to in subparagraph
(a), with the aim of returning individually or
jointly to their 1990 levels these anthropogenic
emissions of carbon dioxide and other greenhouse
gases not controlled by the Montreal Protocol. This
information will be reviewed by the Conference of
the Parties, at its first session and periodically
thereafter, in accordance with Article 7;
(c) Calculations of emissions by sources and removals by
sinks of greenhouse gases for the purposes of
subparagraph (b) above should take into account the
best available scientific knowledge, including of
the effective capacity of sinks and the respective
contributions of such gases to climate change. The
Conference of the Parties shall consider and agree
