The Task Force’s main focus is to combine information produced by the various scientific working groups of the LRTAP Convention and through computer models assist in the development of legal instruments.
The Task Force on Integrated Assessment Modelling (TFIAM) was established by the Executive Body of the Convention on Long-range Transboundary Air Pollution at its fourth session in 1986. In the following years integrated assessment models were developed that provided the basis for negotiation of the 1994 Oslo Protocol and the Gothenburg Protocol in 1999. The Task Force is co-chaired by France and Sweden.
The Task Force’s main focus is to combine information gathered from the Parties and from other Convention bodies and through computer models assist in the development of legal instruments (protocols).

Centre for Integrated Assessment Modelling (CIAM)
Since 1999 IIASA has been hosting the Centre for Integrated Assessment Modelling (CIAM), one of the four centres assigned for the European Monitoring and Evaluation Programme (EMEP) of the Convention on Long-range Transboundary Air Pollution. Read more
Reports, Presentations and Data related to the Gothenburg Protocol Revision
At its 61st meeting (Geneva, 4-6 September 2023), the Working Group on Strategies and Review requested a policy brief on the potential implications of introducing collective risk-based targets for the UNECE region to address air pollution impacts on health and ecosystems. Such a document is being jointly prepared by the Task Force on Integrated Assessment Modelling and the Centre for Integrated Assessment Modelling (CIAM). An overview of the comments received on an early draft, the latest revised version (4 November 2024) of the policy brief and country emissions by GNFR sector, are available below:
- Draft guidance document on non-technical measures (draft, 18 October 2024)
- Overview of comments on earlier version of the Policy Brief (July 2024)
- Policy brief on potential targets to reduce risks for health and ecosystems
- Country emission totals and summaries by GNFR sector (3 February 2025: includes optimized scenarios and revised MTFR)
- Country emissions by GNFR sector (3 February 2025: includes optimized scenarios and revised MTFR)
Forthcoming Meetings
Announcement: The 54th TFIAM-meeting will be held from 3 to 4 April 2025 in Laxenburg, Austria.
The focus of this meeting is on the tasks necessary for TFIAM to support the Air Convention during the revision of the Gothenburg protocol including scenarios targeted at health improvement and biodiversity protection. The draft agenda will be made available here soon.
This TFIAM meeting is held back-to-back with a TAIEX meeting specifically targeted at knowledge sharing on emission inventory and integrated assessment modelling for the EECCA and West Balkan countries and Türkiye, held in Vienna from 31 March to 2 April.
