Austrian Assessment Report (AAR)

In 2014, the first comprehensive national assessment report (AAR14) was published. Austrian researchers working on climate change produced an assessment report on climate change in Austria over a three-year process, modelled on the IPCC Assessment Reports. More than 240 scientists comprehensively evaluated the (then) current state of science and research on climate change, and compiled it in a policy- and practice-relevant way, following the IPCC principle of being "policy-relevant, not policy-prescriptive". The Austrian Climate Research Program (ACRP) of the Climate and Energy Fund made this work possible by funding coordination activities and contributions in kind. 

The Second Austrian Assessment Report on Climate Change (AAR2) was presented on 17 June 2025 at a press conference with Federal Minister Totschnig and the report's scientific steering committee, to considerable media attention across Austria. The report represents the most comprehensive scientific work on climate change in Austria to date.

In cooperation with and supported by the Climate Change Centre Austria (CCCA), the report was developed by around 200 scientists from a range of disciplines, coordinated in an interdisciplinary manner, and reviewed to the highest scientific standards. The AAR2 follows the standards, methodology, and ambition of the international reports of the Intergovernmental Panel on Climate Change (IPCC). It is a product of the Austrian Panel on Climate Change (APCC) — the national counterpart to the IPCC — which is hosted under the umbrella of CCCA.
