Convention on long range transport of air pollutants

CONVENTION ON LONG-RANGE TRANSPORT OF AIR POLLUTANTS

  • LRTAP was the first multilateral treaty on air pollution (1979)

  • LRTAP has developed Protocols to address

    SulphurGround-level ozone

    NOxPersistent Organic Pollutants

    VOCAcidification and Eutrophication

    Heavy Metals

  • LRTAP Protocols have evolved

    • Initial agreements required simple, uniform emission reductions from all parties

    • Current agreements allow differentiated responsibilities to achieve policy goals in a cost-effective manner

CONVENTION ON LONG-RANGE

TRANSBOUNDARY AIR POLLUTION

50 Parties in Europe, North America and Central Asia


Mechanisms of transport in northern mid latitudes

MECHANISMS OF TRANSPORT IN NORTHERN MID-LATITUDES

Transport may be observed as

  • Discrete events in which plumes of pollution can be tracked across oceans and continents

  • An increase in general background concentrations of pollutants

TASK FORCE ON HEMISPHERIC TRANSPORT OF AIR POLLUTIONTF HTAP

  • The TF was created by the LRTAP Executive Body in December 2004

  • The TF is under the leadership of the European Community and the United States

  • The TF participants are Experts:

    • Nominated by national governments;

    • Representing intergovernmental organizations (IGOs) and accredited non-governmental organizations (NGOs);

    • Representing other bodies under the LRTAP Convention;

    • Invited by the Co-Chairs

  • The Executive Body encouraged the TF to engage participants from Non-UNECE countries

TASK FORCE ON HEMISPHERIC TRANSPORT OF AIR POLLUTIONTF HTAP

  • The TF is charged to plan and conduct the technical work necessary to:

    • Develop a fuller understanding of hemispheric transport of air pollution

    • Estimate the hemispheric transport of specific air pollutants for use in review of LRTAP protocols

    • Prepare technical reviews for submission to the Steering Body of EMEP

  • The TF discusses scientific questions, not policy


Task force focus questions

TASK FORCE FOCUS QUESTIONS

1.How does hemispheric transport affect air pollution?

2.How much do emissions in one country or region affect air pollution in another country or region?

3.How confident are we of the results? What is our best estimate of the uncertainties?

  • How will changes in emissions in one country or region affect air pollution in another country or region?

    5.How may these relationships change over the next 20 to 50 years due to changes in emissions?

    6.How may these relationships change due to climate change?

    7.What efforts are needed to develop an integrated system of observation data and models?

  • Assessment reports tf htap

    ASSESSMENT REPORTS: TF HTAP

    2007 Interim Report

    • Investigate the significance of intercontinental transport of air pollutants within the Northern Hemisphere

    • Goal: Inform the review of the Gothenburg Protocol

    • Focus on Ozone and Particulate Matter

      2009 Assessment Report

    • Full assessment of the scientific understanding of hemispheric transport of air pollutants

    • Builds on 2007 Interim report

    • Focus on Ozone and Particulate matter, PLUS Mercury and Persistent Organic Pollutants


    Task force process

    TASK FORCE PROCESS

    • TF Co-Chairs report to the EMEP Steering Body

      • Reports are the consensus of the FULL group of participants

      • Reports and conclusions are NOT by vote

  • Co-Chairs work to provide balance in workshops, meetings, and reports

    • The TF balances multiple regional perspectives, national opinions, and scientific viewpoints

    • TF participants have equal say at meetings and workshops

  • TF process is transparent

    • Up-to-date information is posted on the website (www.htap.org), including:

      • Assessment reports

      • Current and planned analytical activities

      • Upcoming meetings and details of past meetings


  • How can non unece countries participate

    HOW CAN NON-UNECE COUNTRIES PARTICIPATE?

    • Non-UNECE countries can nominate experts to the Task Force

    • Non-UNECE Experts in the Task Force:

      • Are full participants in the Task Force

      • Have equal say meetings and workshops

      • Participate as authors and reviewers of assessment reports

      • Participate in model intercomparisons and other collaborative analyses

    • Non-UNECE countries have also been invited to participate as observers to the EMEP Steering Body and LRTAP Executive Body


    Non unece participation benefits

    NON-UNECE PARTICIPATION: BENEFITS

    • Participate in scientific exchange

      • Air Quality/multi media modeling

      • Satellite/Aircraft observations

      • Fusion of many data sets (ground-based, satellite, aircraft)

      • Emissions inventories and projections

      • Links between air quality and climate change

      • Insights for local and national air quality management

    • Lay foundation for further cooperation

      • Scientific collaboration

      • Management of local/regional air quality

    • Non-UNECE participants can use the tools and expertise from UNECE participants to build technical capacity in their home countries


    Summary

    SUMMARY

    • The Task Force is an effort to build a common understanding of how air quality issues are linked throughout the hemisphere

      • Example: An increase in the background concentration of ozone affects everyone across the hemisphere

    • Participation by all countries in the Northern Hemisphere will ensure robust development of a credible scientific assessment of the intercontinental transport of air pollutants in the Hemisphere

    • The Task Force addresses scientific questions. The TF is not a voting body, and does not make policy

    • The LRTAP Convention may be a useful model for cooperation in other regions or building blocks for broader cooperation, and the LRTAP Parties are interested in furthering bilateral and multilateral cooperation to address air pollution problems

    • The Task Force may offer a way to build connections between such regional efforts as EANET, Male, CAI-Asia, ASEAN, ABC, and GAPF
