Jointly modeling the adoption and use of clean cooking fuels in rural India

Abstract

Solid fuel combustion is a major cause of household air pollution, a leading environmental health risk factor globally. In India, over 750 million people continue to rely on firewood and other solid fuels for daily cooking. We explore the drivers of adoption and use of liquefied petroleum gas (LPG), India’s dominant clean cooking fuel. We document strides in LPG ownership using a panel dataset of over 8,500 rural households from six Indian states surveyed in 2015 and 2018 (ACCESS), partially due to India’s flagship clean cooking policy Pradhan Mantri Ujjwala Yojana (PMUY). We further demonstrate that the drivers of initial LPG adoption also apply to use. While fuel stacking—using solid fuels and LPG jointly—is pervasive, improved rural incomes and education result in the increased use of clean cooking fuels. After adoption, general LPG customers are predicted to consume on average 93 kilograms of LPG yearly (95% confidence interval (CI): 91–95 kg/year). However, PMUY beneficiaries are predicted to consume 27 kilograms of LPG (95% CI: 24–30 kg/year) less on average than general customers each year, even after controlling for socio-economic differences and years of using LPG. Our findings suggest that additional strategies to accelerate the transition to exclusive LPG use among the 80 million households acquiring LPG through PMUY should aim to improve affordability and increase awareness to realize the full benefits of the Government of India’s investments in cleaner cooking.
