The Convention on Long-range Transboundary Air Pollution
and Protocols
Martin WilliamsChairman of the Executive Body of the United Nations Economic
Commission for Europe (UNECE) Convention on Long Range Transboundary Air Pollution
http://www.unece.org/env/lrtap
More than 20 years of international cooperation to combat air pollutionThe scientific basis dates back to the 1960sFirst emphasis on acidification leading to the
adoption of the Convention in 1979In 1980s ground-level ozone and eutrophication
become a target of actionSince 1990s, health-impacts are of major concern:
heavy metals, POPs, fine particles

The Convention on Long-range Transboundary Air Pollution - future action
Review of the Protocol on Heavy Metals (complete 2006)
Addition of new substances to the POPs Protocol – several substances are being reviewed for addition Review of the Protocol to Abate Acidification, Eutrophication and Ground-level Ozone (complete in 2007) possible revision of the Protocol to follow Assessment of intercontinental transport of air pollutants
Outreach to other regions around the world
Implementation of the Convention’s EECCA action plan
In-depth review of reported emissions data to improve data quality
Continued focus on compliance with Protocol obligations
Need for Global Cooperation on Air Pollution Control and Prevention
– Health and environmental costs of air pollution are staggering
– Great deal of activity underway around the world; mostly uncoordinated
– Budgets are limited and need to avoid duplication of effort
– Science showing pollution to be regional, hemispheric and even global in nature
Need for Global Cooperation on Air Pollution Control and Prevention
• Critical need to develop and harmonizehigh quality air pollution data bases across the various regions
• Growing consensus on need for coordinated assessment and pollution control strategies at the hemispheric scale
• A comprehensive global atmospheric pollution convention is one possible outcome to address hemispheric and global pollution issues
• Until then, there are opportunities to build on the efforts of existing regional initiatives, networks, and institutions
The Global Atmospheric Pollution Forum
• Interim Management Committee Comprised of:
-- United Nations Environment Programme (UNEP)-- UN Economic Commission for Europe/ Convention on
Long-range Transboundary Air Pollution (UNECE/LRTAP)-- Clean Air Initiative (CAI)-- Air Pollution Information Network for Africa (APINA)
-- The Inter-American Network for Atmospheric/Biospheric Studies (IANABIS)
-- International Union of Air Pollution Prevention and Environmental Protection Associations
(IUAPPA)-- Stockholm Environment Institute (SEI)
• Secretariat provided by IUAPPA and SEI
Role of the Global Atmospheric Pollution Forum
1. Support efforts of regional networks to tackle air pollution at the regional, hemispheric and global scales; and support development of new networks, where needed
2. Promote sharing of experiences, collaboration and capacity building between regional networks
3. Promote discussion on more effective frameworks to address regional, hemispheric or global air pollution
