1. GLOBAL CO-OPERATION FOR AIR POLLUTION SCIENCE AND POLICY Richard Mills Director General, International Union of Air Pollution Prevention Associations And Kevin Hicks Stockholm Environment Institute Paper presented at BAQ 2004, Agra, India 8 December 2004

2. IUAPPA Founded in 1964 To promote progress in the prevention and control of air pollution Member organisations in some 40 countries Key current issues: -Long-range transport of air pollution -Interaction of climate change and pollution -Transport and air quality in major cities Triennial World Clean Air Congress etc

3. OVERVIEW A few words of history What has changed in the last decade; -Evolving pattern of emissions and impacts -Institutional developments -New and Emerging Issues Possible ways forward: -Regional networks -Hemispheric Co-operation -From regional to global Work of the Forum

4. Sulphur Emissions in Europe since 1980

5. Meanwhile Emissions in Other Regions are increasing, rapidly in some cases

6. REGIONAL AND HEMISPHERIC TRANSPORT IN THE USA African Dust Alaskan & Canadian Forest Fires Smoke & Pollution Asian Dust & Pollution

7. NEW AND EMERGING ISSUES Increased concern in developed and developing countries: Rising emissions in developing world increase concern there, while falling emissions in areas of developed world increase the relative importance of pollution from outside Increasing evidence of hemispheric transport – satellite and remote observation Key pollutants: Particles and Ozone – regional and hemispheric scales Reactive nitrogen – and disturbance of the global nitrogen cycle Interaction of climate change and pollution

8. INSTITUTIONAL RESPONSES Treaty-based systems – sometimes free standing, sometimes environmental chapters of wider agreements – CLRTAP, Mal é, US/Canada, Mercosur Non-Treaty based inter-governmental systems – EANET, APINA Scientific based initiatives e.g. IANABIS, ABC All three models can have valuable and mutually supportive roles. But formal treaty or protocol base likely to be necessary as reciprocal actions and differentiated obligations begin to emerge.

9. MAJOR INITIATIVES IN ASIA Coverage now extensive and complex Malé Declaration, ASEAN Haze Agreement, [UNECE] EANET Indoex, ABC, CAI-Asia

10. Malé Declaration on the Control and Prevention of Air Pollution and its Likely Transboundary Effects in South Asia 8 SACEP countries have agreed to cooperate Network developed (annual meetings of FPs and NIAs) Scientific assessment has started (monitoring network set up in 2003/2004)

11. EANET Acid Deposition Monitoring Network in EAST ASIA EANET aims to: Create common understanding about acid deposition in E Asia Provide inputs to decision making in the region Promote mutual cooperation on issues related to acid deposition Monitoring network is current focus

12. UN Economic Commission for Europe (UN/ECE) Convention on Long-Range Transboundary Air Pollution (CLRTAP) 49 parties to the Convention 8 Protocols signed with commitments to reduce emissions of S, N, VOCs, HMs, POPs Convention structure promotes efficient flow of science to policy and vice-versa: emissions officially reported using EMEP/CORINAIR manual, EMEP transfer model officially recognised, IIASA-Rains model used to develop strategies

13. MODELS FOR GLOBAL CO-OPERATION Co-operative Framework for Regional Networks Hemispheric Co-ordination – Ozone From regional to global regulation – POPs Relevant interventions will depend on pollutant transport characteristics and will be diverse and over- lapping. To address the inevitably complex systems that result a more coherent global framework will become increasingly important.

14. TASKS FOR AN INTER-REGIONAL FORUM Explore common problems and share experience Develop more consistent and compatible systems and approaches; Provide a co-operative framework within which air pollution policies and measures at the hemispheric and global scales can be explored and integrated; Contribute to more balanced debate of the issues surrounding the relationship between air pollution and climate change; Help raise the public profile and understanding of regional and hemispheric air pollution issues.
