Abstract
OnStove is a geospatial tool that evaluates the net benefits of various stoves compared to a defined baseline. The net benefits of all stoves are then compared to each other. The net benefit is the total benefits minus the total costs. The benefits comprise reduced mortality, reduced morbidity, lower emissions, and time saved, and the costs are capital cost, fuel cost, operation, and maintenance costs. The OnStove is modelled in two scenarios(social and private).
