Helping Cambodian households switch from wood and charcoal to electric induction cooking
Applied Implementation Research for Clean Cooking in Cambodia: Equity, Exposure, Costs, and Benefits of Induction Stove Interventions
This project will test whether giving and supporting families in peri-urban Cambodia to use electric induction stoves helps primary cooks stop using wood or charcoal and lowers household air pollution.

What this trial studies
This is a multi-year, cluster-randomized implementation trial across 65 peri-urban villages in Cambodia that compares different approaches to promote induction stove adoption, such as direct sales, subsidies, and community promotion. Households that receive induction stoves will be monitored with cloud-connected data loggers to record stove use and with air pollution monitors before and after intervention. Researchers will collect survey and interview data from about 3,100 households, focusing on primary cooks, and will analyze costs, health impacts, time savings, and environmental effects. The study uses established implementation frameworks (RE-AIM) and a cost-effectiveness analysis to understand which strategies produce sustained, affordable reductions in household air pollution.
Who should consider this trial
Good fit: Households in selected peri-urban Cambodian villages with reliable electricity where an adult primary cook consents and that do not already use induction cooking are eligible.
Not a fit: Households without reliable electricity, those already using electric induction cooking, or those planning to move out of the area within 12 months are unlikely to benefit.
Why it matters
Potential benefit: If successful, this approach could substantially reduce household air pollution exposure for primary cooks and lower related health risks while saving time and fuel costs.
How similar studies have performed: Previous cleaner-stove programs often failed to fully displace biomass cooking or to lower pollution, and large-scale promotion of induction cooking in low-resource settings remains relatively novel with limited prior proven success.
