This study investigates the impact of a clean cooking intervention on primary fuel choice and on households’ willingness to pay for an improved LPG distribution model in Ghana. Using data obtained via a survey of 904 households in two beneficiary districts, we found that the intervention led to higher LPG usage. The program increases the probability of households choosing LPG as a primary cooking fuel by 24% and the rate of use of LPG among households by 33%. Furthermore, an analysis of willingness to pay shows that delivery preference is not statistically different between beneficiary and control groups. The distance to refill the cylinder significantly affects LPG usage and willingness to pay. A policy that brings LPG refill closer to households and reduces the time and money cost of accessing a refill station is key to increasing the adoption of LPG as the primary cooking fuel.

本研究调查了清洁烹饪干预对加纳主要燃料选择和家庭为改进 LPG 分配模式支付意愿的影响。使用通过对两个受益区的 904 户家庭进行的调查获得的数据，我们发现干预导致 LPG 使用量增加。该计划使家庭选择液化石油气作为主要炊事燃料的可能性增加了 24%，家庭中液化石油气的使用率增加了 33%。此外，对支付意愿的分析表明，受益人和对照组之间的交付偏好没有统计学差异。加注气瓶的距离显着影响液化石油气的使用和支付意愿。
