实验室研究表明，改进的炉灶可以减少室内空气污染，改善健康状况，并减少发展中国家的温室气体排放。我们从印度的一项大规模随机试验中提供了证据，证明了一种经过实验室验证的普通炉灶的好处，并进行了为期四年的随访。虽然烟雾吸入最初福尔斯下降，但这种影响在第二年消失。我们没有发现健康结果或温室气体排放的变化。家庭不定期和不适当地使用炉灶，不进行维护，使用率随着时间的推移而下降。这项研究强调了在现实环境中测试环境技术的必要性，在现实环境中，行为可能会破坏潜在的影响。
Laboratory studies suggest that improved cooking stoves can reduce indoor air pollution, improve health, and decrease greenhouse gas emissions in developing countries. We provide evidence, from a large-scale randomized trial in India, on the benefits of a common, laboratory-validated stove with a four-year follow-up. While smoke inhalation initially falls, this effect disappears by year two. We find no changes across health outcomes or greenhouse gas emissions. Households used the stoves irregularly and inappropriately, failed to maintain them, and usage declined over time. This study underscores the need to test environmental technologies in real-world settings where behavior may undermine potential impacts.
