Household air pollution remains a major threat to health in developing countries, attributed to an estimated 2.6 million premature deaths in 2016. Though the use of clean fuel such as liquefied petroleum gas (LPG) could alleviate this burden, the high cost of LPG makes it unaffordable for the majority of rural populations. We propose to conduct a series of observations, interviews, and systematic water boiling tests to identify strategies for gas conservation, and evaluate the impact of these strategies on gas consumption and emissions when implemented with rural households in Puno, Peru. This study will leverage the ongoing Cardiopulmonary outcomes and Household Air Pollution (CHAP) trial in Puno, Peru. The results will inform the development of a toolkit for promoting LPG conservation to increase the affordability of exclusive LPG use, which could be integrated into clean energy programs across low- and middle-income settings.
