Using a randomized experimental design, real-time electronic stove surface temperature measurements and controlled cooking tests, we estimate fuelwood and CO₂ savings from an improved cookstove (ICS) program in rural Ethiopia. Cooking uses a majority of the fuelwood in the country and therefore is a critical determinant of greenhouse gas emissions. Estimating fuelwood savings is therefore a key aspect of crediting ICS climate change benefits. Our findings suggest that the Mirt injera stove saves a substantial amount of fuelwood. Using a relatively low estimate of percentage of nonrenewable biomass, on average one Mirt stove avoids the burning of approximately 634 kg of fuelwood per year and sequesters an additional 0.65 tons of CO₂, which is about one-third of previous estimates. The U.S. Interagency Working Group (2013) 2015–2019 estimate for the global social cost of carbon of $44.00 per ton implies annual global benefits from reduced fuelwood burning of $28.60 per stove per year, which substantially exceeds the $12.00 initial cost of the stove. As the global benefit is much greater than the cost, which is borne entirely by Ethiopia, international transfers would be warranted to support expansion of Mirt adoption.

使用随机实验设计、实时电子炉表面温度测量和受控烹饪测试，我们估计埃塞俄比亚农村改进炉灶 (ICS) 计划所节省的薪材和 CO _{2 。}烹饪使用该国大部分薪材，因此是温室气体排放的关键决定因素。因此，估算薪材节省是 ICS 气候变化收益的一个关键方面。我们的研究结果表明，Mirt injera 炉子可以节省大量薪柴。使用相对较低的不可再生生物质百分比估计值，平均一个Mirt炉子每年可避免燃烧约 634 公斤薪柴，并额外隔离 0.65 吨 CO ₂，大约是之前估计的三分之一。美国机构间工作组 (2013) 对 2015-2019 年全球碳社会成本的估计为每吨 44.00 美元，这意味着每年每炉子减少薪柴燃烧带来的全球收益为每年 28.60 美元，这大大超过了 12.00 美元的炉子初始成本。由于全球收益远大于成本，成本完全由埃塞俄比亚承担，因此有必要进行国际转移以支持扩大Mirt的采用。
