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.

CIAM prepares technical background material for the annual meetings of the Task Force on Integrated Assessment Modelling (TFIAM). The Task Force brings together information gathered from the Parties and from other Convention bodies on cost-effective emission control strategies. Its regular reports to the negotiating bodies of the Convention assist - through computer models - in the development of legal instruments (protocols).

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:
