25th SESSION OF THE INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE: 

26-28 APRIL 2006

The twenty-fifth session of the Intergovernmental Panel on Climate 
Change (IPCC-25) begins today in Port Louis, Mauritius. Delegates 
will consider a range of matters concerning the work, budget and 
organization of the IPCC, including: acceptance and adoption of 
the 2006 IPCC Guidelines for National Greenhouse Gas Inventories 
(2006 Guidelines); further work on emissions scenarios; election 
procedures for the IPCC Bureau and any Task Force Bureau; the IPCC 
communications strategy and outreach activities; a process and 
policy for admitting observer organizations; and the future work 
programme of the IPCC Task Force on National Greenhouse Gas 
Inventories. Delegates will also hear progress reports, including 
on the activities of the three IPCC Working Groups and the Task 
Group on Data and Scenario Support for Impact and Climate Analysis. 

A BRIEF HISTORY OF THE IPCC

The IPCC was established in 1988 by the World Meteorological 
Organization (WMO) and the United Nations Environment Programme 
(UNEP). The purpose of the IPCC is to assess the scientific, 
technical and socioeconomic information relevant to understanding 
the risks associated with human-induced climate change. The IPCC 
does not undertake new research, nor does it monitor climate-
related data, but bases its assessments on published and peer-
reviewed scientific and technical literature. Its Secretariat is 
located in Geneva, Switzerland, and is staffed by the WMO and UNEP.

Since its inception, the IPCC has prepared a series of 
comprehensive assessments, special reports and technical papers, 
which provide scientific information on climate change to the 
international community, including policy makers and the public. 
This information has played an important role in the negotiations 
under the United Nations Framework Convention on Climate Change 
(UNFCCC).

The IPCC currently has three working groups: Working Group I 
addresses the scientific aspects of the climate system and climate 
change; Working Group II addresses the vulnerability of 
socioeconomic and natural systems to climate change, negative and 
positive consequences of climate change and adaptation options; 
and Working Group III addresses options for limiting greenhouse 
gas emissions and otherwise mitigating climate change. 

The IPCC also has a Task Force on National Greenhouse Gas 
Inventories. This Task Force oversees the IPCC National Greenhouse 
Gas Inventories Programme (NGGIP), which aims to develop and 
refine an internationally-agreed methodology and software for the 
calculation and reporting of national greenhouse gas emissions and 
removals, and to encourage the use of this methodology by 
countries participating in the IPCC and by UNFCCC signatories. The 
IPCC Bureau, composed of 30 members elected by the Panel, assists 
the IPCC Chair in planning, coordinating and monitoring progress 
in the work of the IPCC.

KEY IPCC PRODUCTS: The IPCC completed its initial comprehensive 
assessments of climate change in the First Assessment Report in 
1990 and the Second Assessment Report in 1995. The IPCC’s Third 
Assessment Report (TAR) was completed in 2001. It addresses 
policy-relevant scientific, technical, and socioeconomic 
dimensions of climate change, and concentrates on findings since 
1995 at both regional and global levels. The TAR, which was 
subject to extensive review from experts and governments, is 
composed of a comprehensive assessment from the three IPCC Working 
Groups, a Summary for Policy Makers (SPM), a Technical Summary of 
each Working Group report, and a Synthesis Report. The TAR 
Synthesis Report is written in a non-technical style aimed at 
policy makers and discusses nine policy-relevant questions 
identified by the IPCC based on submissions by governments. The 
IPCC’s Fourth Assessment Report (AR4) is due to be released in 
2007. 

The IPCC Guidelines for National Greenhouse Gas Inventories, which 
are used for calculating and reporting national greenhouse gas 
emissions and removals, were first released in 1994, and a revised 
set was released in 1996. In 2000 and 2003, the Panel approved 
additional good practice guidance reports that complement the 
Revised 1996 Guidelines and, in 2003, approved a process for a 
further revision of the Guidelines by early 2006.

NINETEENTH SESSION: At IPCC-19, held from 17-20 April 2002, in 
Geneva, Switzerland, the IPCC began work on the AR4. The Panel 
took a number of decisions, including those in relation to a draft 
workplan for developing definitions for forest degradation and 
devegetation, methodological options for recording and reporting 
on emissions from these activities, and aspects of the procedures 
for agreeing on NGGIP products. Delegates also decided: on the 
timing of the AR4; to hold a workshop on geological and oceanic 
carbon dioxide separation, capture and storage; to draft a scoping 
paper on climate change and water; and to hold an expert meeting 
on climate change and development.

TWENTIETH SESSION: IPCC-20 was held from 19-21 February 2003, in 
Paris, France. Delegates agreed on a workplan for two expert 
“scoping meetings” on how to structure the AR4. They discussed a 
framework and a set of criteria for establishing priorities for 
special reports, methodology reports and technical papers for the 
period of the fourth assessment. The Panel also decided to hold a 
high-level scientific meeting to survey the processes affecting 
terrestrial carbon stocks and human influences upon them, and to 
produce two special reports: one on safeguarding the ozone layer 
and the global climate system; and the other on carbon dioxide 
capture and storage.

TWENTY-FIRST SESSION: At IPCC-21, held from 3-7 November 2003, in 
Vienna, Austria, delegates reviewed the outlines of the proposed 
Working Group contributions to the AR4 and the Chair’s proposal 
for an AR4 Synthesis Report. The Panel agreed that a technical 
paper on climate change and water should be completed in 2007, 
discussed terms of reference for a document on the AR4 product 
set, and reviewed the report of the IPCC expert meeting on 
processes affecting terrestrial carbon stocks and human influences 
on them. Delegates also approved the terms of reference for 
reviewing the Revised 1996 IPCC Guidelines for National Greenhouse 
Gas Inventories, and agreed on a revised mandate and changed the 
name of the Task Group on Scenarios for Climate and Impacts 
Assessment to the Task Group on Data and Scenario Support for 
Impact and Climate Analysis (TGICA). 

TWENTY-SECOND SESSION: IPCC-22 convened from 9-11 November 2004, 
in New Delhi, India. Delegates discussed the scope, content and 
process for an AR4 Synthesis Report, AR4 products, outreach, the 
IPCC programme and budget for 2005-08, and election procedures. 
The Panel adopted a decision on the IPCC programme and budget for 
2005-08 and agreed to work towards a 30-page AR4 Synthesis Report 
with a five-page SPM to be approved by the IPCC in late October 
2007.

TWENTY-THIRD SESSION: At IPCC-23, which convened on 8 April 2005, 
in Addis Ababa, Ethiopia, delegates considered the joint 
activities of Working Groups I and II on the Special Report on 
Safeguarding the Ozone Layer and the Global Climate System. The 
Panel accepted this Special Report along with an SPM. In adopting 
the draft report of IPCC-22, delegates also agreed that the IPCC 
Bureau would further consider arrangements for management of the 
AR4 Synthesis Report and report back on its progress.

TWENTY-FOURTH SESSION: IPCC-24 was held from 26-28 September 2005, 
in Montreal, Canada. Delegates approved the Special Report on 
Carbon Dioxide Capture and Storage and the SPM. Delegates 
discussed further work on aerosols and on emissions scenarios, 
outreach activities, and admittance of observer organizations, but 
did not reach agreement on revised election procedures for the 
IPCC Bureau and any Task Force Bureau. Delegates also decided to 
establish a Task Group on New Emissions Scenarios (TGNES), with a 
lifetime up to IPCC-25, to further define the emissions scenarios 
development process. 

INTERSESSIONAL HIGHLIGHTS 

ELEVENTH CONFERENCE OF THE PARTIES TO THE UNFCCC AND FIRST MEETING 
OF THE PARTIES TO THE KYOTO PROTOCOL: The eleventh Conference of 
the Parties to the UNFCCC (COP 11) and the first Conference of the 
Parties serving as the Meeting of the Parties to the Kyoto 
Protocol (COP/MOP 1) took place in Montreal, Canada, from 28 
November to 10 December 2005. Parties also met for the twenty-third  
sessions of the Subsidiary Bodies (SB 23). 

At COP/MOP 1, parties adopted decisions on the operational details 
of the Kyoto Protocol, including the package of decisions known as 
the “Marrakesh Accords,” and on a process for considering post-2012  
commitments. Parties also adopted the IPCC’s Good Practice Guidance  
on Land Use, Land-Use Change and Forestry (LULUCF) for reporting  
during the first commitment period of the Kyoto Protocol 
(2008-2012). COP 11 addressed issues such as capacity building, 
technology development and transfer, the adverse effects of 
climate change on developing and least developed countries, and a 
process for considering future action beyond 2012 under the 
UNFCCC. In its decision on long-term cooperative action to address 
climate change by enhancing implementation of the UNFCCC, the COP 
resolved to engage in a non-binding dialogue that would be 
informed by the IPCC. Parties also agreed to a five-year work 
programme for the Subsidiary Body for Scientific and Technological 
Advice (SBSTA) on impacts, vulnerability and adaptation to climate 
change, and requested that SBSTA, at its twenty-eighth session, 
consider additional activities based on new information, including 
that presented in the AR4.

SBSTA 23 considered the IPCC’s Special Report on Carbon Dioxide 
Capture and Storage and, inter alia, requested the UNFCCC 
Secretariat to organize an in-session workshop at SB 24 on carbon 
dioxide capture and storage, and encouraged parties and the 
private sector to support research and deployment of such 
technologies. In relation to harvested wood products, SBSTA noted 
with appreciation the IPCC report on progress made in estimating 
and reporting harvested wood products in the context of preparing 
its 2006 Guidelines, and decided to continue consideration of this 
issue at SBSTA 24.

ELEVENTH SESSION OF THE TGICA: At the eleventh meeting of the 
TGICA, held in Cape Town, South Africa, from 7-9 February 2006, 
participants discussed matters that included management of the 
Data Distribution Center and the status of a TGICA initiative to 
build capacity and develop appropriate data products for use in 
developing countries and countries with economies in transition. 
They also prepared a comment on the draft recommendations of the 
TGNES, to be considered at IPCC-25.

IPCC EXPERT MEETING ON NEW EMISSIONS SCENARIOS: At this meeting, 
held from 20-22 March 2006, in Seville, Spain, participants 
discussed proposals of the TGNES for developing emissions 
scenarios, including: possible IPCC coordination and facilitation 
with the scientific community; the process, timeline and 
deliverables of new emissions scenarios development; the 
organizational arrangements for the IPCC’s own activities on 
scenarios; and the possibility of encouraging a wider family of 
non-climate scenarios that might include emissions scenarios.
