SLCPs: Short-Lived Climate-forcing Pollutants • Aerosol Particles: Gases: • – Soot (incl. Black Carbon (“BC”)) – Methane (CH 4 ) – Organic Carbon – Ozone (O 3 ) – Sulfate (SO 4 2- ) – Hydrofluorocarbons (HFCs) – Etc. – Etc. Roles • Act as air pollutants or pollutant precursors (except HFCs) • Responsible for significant climate-forcing (warming /cooling) • Relatively short-lived in the atmosphere (days to decades) Institute for Advanced Sustainability Studies e.V. 7
Mitigation Possibilities? è 16 Key Global Measures for CH 4 and BC Institute for Advanced Sustainability Studies e.V. 8 [UNEP, 2011]
9 Key Global Measures for Reducing BC Emissions è è Many are typical for (South) Asia! Remove mega-emitters / DPF Modern coke ovens Improved biomass stoves Cooking with clean fuel Improved brick kilns Pellet biomass heating stoves Coal briquettes replacing coal Reduce agricultural burning Reduce flaring 9 (Courtesy of J. Kuylenstierna, SEI/CCAC)
Clear Need for: • clean-solutions • grounded in sound science • tailored to local context è One Response: Pilot Studies (our example: Nepal) è Significant levels of pollution (Transformation needs), but… • Manageable size for potential interventions (Transformation potential) • à Collaboration with ICIMOD and over 20 other research institutions Institute for Advanced Sustainability Studies e.V. 10

Conc nclu lusions ns • Science has made a strong case that cannot be ignored: SLCPs are a significant threat to development in Asia • Need to continue advancing SLCP science in the region • Connect to local policy makers and other key stakeholders: especially showing benefits near where emissions are cut, plus extension to other regions through climatic and The Goal: Clean Air economic impacts for Asia!
