After three years of work, the COP, at its sixteenth session, agreed that developed countries
will implement under the Convention quantified economy-wide emission targets for 2020 as
communicated by these Parties.
The COP urged developed country Parties to increase the ambition of their economy-wide
emission reduction targets, with a view to reducing their aggregate anthropogenic emissions
of carbon dioxide and other greenhouse gases not controlled by the Montreal Protocol to a
level consistent with the Fourth Assessment Report of the Intergovernmental Panel on Climate
countries communicated targets under the Convention. The targets communicated by
are generally not represented as a single unconditional value, but as a single conditional
value or a range of values. Conditions relate to the following: achieving a comprehensive
global agreement, with the participation of all major economies; advanced economies agreeing
to comparable mitigation efforts and actions; developing countries taking action in
accordance with their differentiated responsibilities and respective capabilities; and all
Parties contributing their fair share to a cost-effective global emission reduction pathway.
Other conditions and assumptions relate to an effective set of rules for LULUCF.
Also, the COP, at its sixteenth session, launched a process for clarification of the
assumptions and the conditions related to the attainment of these targets, including the use
of carbon credits from the market-based mechanisms and land use, land-use change and forestry
activities, and options and ways to increase their level of ambition.
The COP, at its seventeenth session, decided to continue in 2012 the process of clarification
of the developed countries targets, in particular focusing on enhancing understanding on base
year, global warming potential (GWP) values, coverage of gases, coverage of sectors, expected
emission reductions, and the role of land use, land-use change and forestry (LULUCF), and
carbon credits from market-based mechanisms, and associated assumptions and conditions
related to the ambition of the pledges. To support this process, Parties submitted further information on their targets, four
in-session workshops were organized and the secretariat produced a technical
paper synthesizing all available information. Reports of the workshops and presentations
made by Parties can be found in the following link:

The COP, at its eighteenth session, decided to establish a work programme under the SBSTA to
continue the process of clarifying the targets in 2013 and 2014. Thus, discussions on
identifying common elements for measuring the progress made towards the achievement of the
quantified economy-wide emission reduction targets and ensuring the comparability of efforts
among developed country Parties, taking into account differences in their national
circumstances, are on-going under the SBSTA.
