Intergovernmental Panel on Climate Change (IPCC)
The IPCC is the United Nations body for assessing the science related to climate change.
The IPCC was created to provide policymakers with regular scientific assessments on climate change, its
implications and potential future risks, as well as to put forward adaptation and mitigation options.
Founded 1988 by UNEP and WMO
No research, no monitoring, no recommendations
Only assessment of peer-reviewed literature
Authors academic, industrial and NGO experts
Reviews by independent Experts and Governments
Policy relevant, but NOT policy prescriptive
Full report and technical summary: accepted by governments without change
Summary for policymakers: government approval
The Intergovernmental Panel on Climate Change (IPCC) was founded in 1988 by the United
Nations Environmental Programme and the World Meteorological Organisation to assess
scientific, technical and socio-economic information on the science, impacts and mitigation of
climate change. Its reports are broadly regarded as authorative and are influential in the climate
policymaking process. The quality of the IPCC reports is guarded by an extensive and long
process; it takes several years to publish a report. Only peer-reviewed literature is used as the
basis for the assessment, the authors are from different disciplines, parts of the world, and work
in different organisations (universities, industry, NGO’s, research institutes, international
organisations). The reports are reviewed in several steps: first internally, then by experts, then
by experts and governments.The mantra of IPCC is that its reports must be policy relevant, but
not policy prescriptive, and IPCC does not “favour” technologies or make recommendations on
policies. The full report and technical summary are the responsibility of the authors and are
accepted by governments without change. An important aspect is that the governments in the
IPCC approve the SPM line by line and by doing that, acknowledge the results in that summary.
The IPCC is organised in three working groups and one task force. Working Group I deals with
the science of climate change. It's technical support unit is in Boulder, Colorado. Working Group
II works on the impacts of climate change and adaptation. Its technical support unit is at the
