  1. High Level Sub-regional Consultation on Advancing Action on Short-Lived Climate Pollutants (SLCPs) in Southeast and Northeast Asia, 19th August 2014, Bangkok, Thailand

  2. What are SLCP ? Short-Lived • Stays in atmosphere for short duration (weeks) [vs. CO2 (centuries) Climate • Has the potential to affect the climate Pollutant • Has the potential to deteriorate the air quality

  3. SLCPs • SLCPs is a collective term • Black carbon (BC) • Tropospheric ozone (O3) • Methane (CH4) • Hydroflurocarbons (HFCs) • ~40% of present climate forcing due to SLCPs • Reducing SLCPs most effective strategy for constraining warming in near term- technologies with incremental benefits available • Co-benefit: Health and Food security (main drivers of policy change ?)

  4. Project Surya • Kitchen Smoke in 500 million households: Pollute climate + Health hazard • October 2009 in IGP (India) • Partners: LOGOS

  5. Methods and Results

  6. Ambient Data Collection

  7. Indoor Data Collection

  8. Cooking drives BC in village • Strong diurnal pattern, with peaks during morning and evening cooking hours • Cooking period BC ~ 5 X Non-cooking period BC • Ambient BC concentrations about an order of magnitude larger than BC values in most polluted cities in developed countries

  9. Testing of “improved” biomass cookstoves • Dependence on biomass as cooking fuel in 2030 • Supply constraints • Economics • Focus on clean and affordable stoves • Forced Draft: “Gasifier” stoves with two-stage combustion aided by fan • Natural Draft: Improved one stage burning- “rocket elbow” combustion chamber

  10. Improved stoves are not equal • Performance • Air quality: BC concentration • Fuel Consumption • Convenience • Fuel processing • Service • Price • Life

  11. Why clean stoves are useful for end users? • Improved combustion efficiency (90% to 99%): Less smoke • Improved heat transfer efficiency (15% to 50%): Fuel Saving • Less Cooking Time (5% to 30%)

  12. SLCPs as part of ETS • In spite of its importance, SLCPs not included in carbon market • Project Surya developed world’s first methodology to • Valuate in CO2e form • Validate using cell phone technology • Reward IC users for reduction in SLCPs • Partnership with Gold Standard Foundation to peer review and register the methodology • Rolled out 5000 households as part of a dummy carbon market in form of C2P2_McQuown5000
