摘要: Cook stoves that produce biochar as well heat for cooking could help mitigate indoor air pollution from fires and enhance local soils, while their potential reductions in carbon (C) emissions increases soil C sequestration offer access to market financing. We use system dynamics modeling (i) investigate the climate change impact of prototype refined biochar-producing pyrolytic cook improved combustion comparison conventional stoves; (ii) assess relative sensitivity stoves' impacts key parameters; (iii) quantify effects different accounting decisions. Simulated mean greenhouse gas (GHG) a traditional, 3-stone stove baseline are 3.50 tCO2e/household/year 3.69−4.33 stoves, which directly accounts 26−42%. The magnitude these is about 2−5 time...
