2. Background – EPA’s Stove Research Conducted research on coal-burning stoves in China in 1980s http://www.sciencemag.org/content/235/4785/217 http://www.sciencemag.org/content/235/4785/217 Sponsored cookstove research led by Kirk Smith in 1990s http://ehs.sph.berkeley.edu/krsmith/?p=249http://ehs.sph.berkeley.edu/krsmith/?p=249 Developed regulatory program for certifying wood-burning heating stoves in the U.S. from 1980s to present http://www.epa.gov/burnwise/woodstoves.htmlhttp://www.epa.gov/burnwise/woodstoves.html Provided technical support to Partnership for Clean Indoor Air 2002- 2012 (now integrated with the Global Alliance for Clean Cookstoves) http://www.pciaonline.org/ http://www.pciaonline.org/ 2

3. Cookstove Testing Conducted a first round of cookstove tests in 2007 – Initial independent evaluation of laboratory performance – Results published http://www.pciaonline.org/files/Stoves_Paper_Final_Color_2.26.09.pdf Conducted a second round of cookstove tests in 2010 – Tested newer model stoves and more fuel types – Measured emissions of additional air pollutants – Evaluated performance with two fuel moisture levels – Helped support development of IWA guidelines for performance – Results published http://ehs.sph.berkeley.edu/krsmith/?p=1387 A third round of tests is currently in progress – Testing additional fuels (LPG, alcohol, kerosene) and solar cookers – Helping to address increasing demand for independent testing – Supporting development of regional testing centers – For more info: http://www.pciaonline.org/files/PCIA-Bulletin-Issue-30.pdf 3

6. Current Research Activities Laboratory testing of cookstoves coordinated with field testing (sponsored by EPA Office of Air and Radiation) Laboratory testing of solar cookers Health effects studies –Mutagenicity potential –Animal exposure STAR (Science to Achieve Results) grants http://www.epa.gov/ncer/rfa/2012/2012_star_cook_heat_light.html http://www.epa.gov/ncer/rfa/2012/2012_star_cook_heat_light.html Decision support tool (database development) Navajo Nation coal stove study http://www.daily-times.com/ci_22359594/scholars-visit-shiprock-talk-about-fuel-alternatives http://www.daily-times.com/ci_22359594/scholars-visit-shiprock-talk-about-fuel-alternatives 6

7. Air Pollutant Emissions Testing 7 Seth Ebersviller, U.S. EPA Post-doctoral Fellow, tests a cookstove for air pollutant emissions and fuel efficiency

8. Laboratory Test Parameters Fuel consumption, energy efficiency, power PM (particulate matter), integrated samples: gravimetric PM, real-time: SMPS, APS CO (carbon monoxide), CO 2 (carbon dioxide): infrared analyzers CH 4 (methane), THC (total hydrocarbons): FID analyzers NO X (nitrogen oxides): chemiluminescence analyzer Black carbon: aethalometer, transmissometer Organic carbon, elemental carbon: thermal-optical analysis Aerosol light absorption and scattering, in situ: PASS-3 and nephelometer 8
