The long term global is to hold the increase in the global average temperature to well
below 2°C above pre-industrial levels, and to pursue efforts to limit the temperature increase to
1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and
impacts of climate change.
This long-term global goal was agreed by the COP in December 2015 (see paragraph 4
of Decision 10/CP.21 on
the 2013-2015 review). It is also reflected in Article 2.1(a) of the
Paris Agreement (see Decision 1/CP.21 and
its annex). The outcome of the 2013-2015 review was a contributing factor to
Parties' strengthening of the long-term global goal.
The periodic review
In 2010, Parties had agreed on a long-term global goal to reduce GHG emissions so as to hold the increase in
global average temperature below 2°C above pre-industrial levels. The COP also decided to
periodically review: (1) the adequacy of the long-term global goal in the light of the
ultimate objective of the Convention, and
(2) overall progress toward achieving the long-term global goal, including a consideration of the
implementation of the commitments under the Convention. See decision 1/CP.16, paragraphs 138-140 for more information.
One year later, the COP decided to establish a structured expert dialogue (SED) to support the
review and to ensure scientific integrity through a focused exchange of views, information and ideas.
The final report on the SED is contained in FCCC/SB/2015/INF.1. The first periodic review was the
2013-2015 review (see "What was the 2013-2015 review" below for more information).
It led to the decision (10/CP.21) on the new
long-term global goal that was agreed in 2015.
Current status of discussions
In 2015, COP 21 requested the SBSTA and the SBI to consider the scope of the next periodic review with
a view to forwarding a recommendation for consideration by the COP by no later than 2018, as
appropriate. It agreed that the next periodic review should be conducted in an
effective and efficient manner, avoid duplication of work and take into account the results of relevant work
conducted under the Convention and its Kyoto Protocol and the subsidiary bodies.
In May 2016, at their forty-fourth sessions, the SBSTA and the SBI considered the scope of the next
periodic review, as mandated at COP 21. They noted the relevant work on
the global stocktake under the APA, the facilitative
dialogue, which will take place in 2018, and the technical examination processes. The conclusions can
be found in the respective reports: SBSTA (page
14) and SBI (page 26).
Outlook for the next session
In May 2016, the SBSTA and SBI agreed to
further consider the scope of the next periodic review at their forty-sixth sessions (May 2017) and
to refine it, taking into account relevant experiences with the 2013–2015 review.
The SBSTA and the SBI noted that an in-session workshop on the scope of the next periodic review could
be useful and that they may consider the matter further at their forty-sixth sessions. An informal background note
(202 kB) has been produced by the Chairs of the SBSTA and the SBI to inform further consideration, at SB
46, on the scope of the next periodic review of the long-term global goal under the Convention and of
progress towards achieving it.
