REG mechanisms in North-East Asia: 1992-1999

(Sub)regional Environmental Governance in Asia and the Pacific

Mechanisms for Comprehensive Cooperation

NEASPEC (Northeast Asian Subregional Program for Environmental Cooperation) established in 1993, 6 countries

NEAC (Northeast Asian Conference on Environmental Cooperation) established in 1992, 5 countries (now discontinued)

TEMM (Tripartite Environment Ministers Meeting) in 1999, 3 countries

Mechanisms for Governing the Commons

NOWPAP (Northwest Pacific Action Plan) in 1994, 4 countries EANET (Acid Deposition Monitoring Network in East Asia) in 1998, 13

countries LTP (Joint Research Project on Long Range Air Pollutants) in 1995, 3

Goal: reduce environmental impacts by acid deposition

Membership: covering 13 countries with 54 monitoring sites

1993, expert meeting

1998, intergovt’meeting

2012,Formal agreement-“Instrument”

Geographic scope: China, Japan and the Republic of Korea

Programme scope: Monitoring and modeling including S-R relationship

Subject scope: sulfur, nitrogen, PM, ozone and others

Long-range Transboundary Pollution (LTP)

Estimate emissions among three countries Research on monitoring and modeling Produce S-R relationships among countries

Establish a foundation for joint researchEstablish database on the concentration and

emissions of air pollutantsEstablish a modeling system

Modeling S-R Relationship

Monitoring Long-range Transport of Air Pollution

Monitoring Stations of LTP

Implication of Modeling and Monitoring• Value disparity exists among countries but significantly

narrowed • Not interference by politics in computing given data but

in advancing overall modeling exercise• scientific shortcomings in taking account of various

factors (seasonal variations, microclimatic conditions, nonlinear chemical reactions, etc)

• Updated data with better quality• Expanding data sharing with expansion of monitoring

stations• Expanding chemical species (O3, PM2.5, VOCs, POPs,

etc)

Technical measures

Implication in institutional context

• Conflicting national interests among initiators of each mechanism, and between source and receptor countries

• Limited model comparison work and policy linkage

• Limited participation of academic community, thereby weak epistemic community

Harnessing benefits of knowledge and experiences from other regions to strengthen consensual knowledge
