低效生物质炉灶产生的烟雾加剧了全球气候变化，每年造成约400万人死亡。减少碳排放的信贷可以潜在地补贴减少这些有害影响的节能炉灶。了解监测炉子使用情况的不同方法的准确性，有助于衡量炉灶项目的效果，并以碳信用额为目标。本文比较了测量炉子使用情况的四种方法：烹饪时间（来自炉子使用情况监测和炉子使用情况观察的预测逻辑回归）；在家庭饮食日记中报告的做饭人数；厨房性能试验中收集的燃料重量；以及家庭空气污染，使用颗粒空气监测仪收集的颗粒物质的24小时平均浓度。我们发现这六对测量中有五对之间存在统计学上显著的正相关。虽然相关性是正的，但每项指标对另一项指标的解释能力都很弱。这种弱相关性强调了对研究人员和碳审计人员来说，使用多种措施来跟踪炉子使用变化的重要性。(C) 2016 Elsevier B.V.版权所有
Smoke from inefficient biomass cookstoves contributes to global climate change and kills approximately four million people per year. Credits for reduced carbon emissions can potentially subsidize fuel-efficient cookstoves that reduce these harmful effects. Understanding the accuracy of different methods of monitoring stove usage is useful to measure the effects of cookstove programs and to target carbon credits. This paper compares four methods of measuring stove usage: hours cooked (derived from a predictive logistic regression of stove usage monitors and observations of stoves in use); number of people cooked for reported in household food diaries; fuel weight used gathered in a kitchen performance test; and household air pollution using mean 24-hour concentrations of particulate matter collected with particulate air monitors. We find statistically significant positive correlations between five out of six of these pairs of measures. While the correlations are positive, the explanatory power of each measure for another is weak. The weak correlations emphasize the importance of using multiple measures to track changes in stove use for both researchers and carbon auditors. (C) 2016 Elsevier B.V. All rights reserved.
