This research evaluates six clean burning cookstove designs for potential mass production in Cameroon using the Analytic Hierarchy Process, a structured multi-criteria decision-making method. The evaluation aligned with the ISO and IWA Tiers of Performance framework, assessing eight parameters that included thermal efficiency, specific fuel consumption, and high, low, and indoor emissions of carbon monoxide and particulate matter. Findings indicate that optimal cookstove selection depends heavily on local priorities. The charcoal stove proved superior for combustion efficiency with a twenty-four percent priority score, whereas the Kirk Harris top-lit updraft stove led in emissions reduction with a thirty-seven percent score. The decision-making model demonstrated mathematical robustness through sensitivity analysis and an acceptable consistency ratio, providing a systematic approach to balance technical output with environmental and user requirements.
Choosing the best clean cookstove involves balancing lower fuel consumption against harmful smoke emissions. By systematically scoring different designs against international performance tiers, this approach helps regional planners and manufacturers select cookstove concepts that best address their most pressing local challenges, whether that is combating indoor air pollution or conserving scarce biomass resources.
The findings directly assist cookstove manufacturers and energy policymakers in selecting verified stove concepts for mass production and deployment in Cameroon and comparable settings. The study represents an applied decision-making stage, evaluating existing stove prototypes to guide commercial manufacturing choices and regional clean cooking rollouts based on specific health or fuel-efficiency targets.

This study used the Analytic Hierarchy Process (AHP), a multi-criteria decision making (MCDM) method to evaluate six clean-burning cookstove designs - the Natural Draft Sunken Pot Rocket Stove, the Kirk Harris TLUD Stove, the Side Feed Bottom Air Forced Draft Stove, the Top Lit Forced Draft Stove, the Charcoal Stove and the SSM Jet-Flame Stove -for mass production in Cameroon, addressing the dual priorities of thermal efficiency and emissions reduction under the ISO/IWA Tiers of Performance framework. Building on a prior quantitative survey of cookstove performance, eight criteria— thermal efficiency, specific consumption, high and low power emissions (CO, PM2.5), indoor emissions (CO, PM2.5). —were used to assess the designs. Pairwise comparisons showed the charcoal stove as optimal for combustion efficiency (24% priority score) and the Kirk Harris TLUD stove as superior for minimizing emissions (37% score), demonstrating that design suitability depends on context-specific energy and environmental goals. The AHP methodology was validated through sensitivity analysis and a consistency ratio below 10%, confirming its robustness for structured decision-making. By systematically balancing technical performance, user needs, and environmental impact, this study underscores AHP’s utility in guiding the selection of clean energy technologies. The findings provide policy makers and manufacturers with actionable insights to prioritise designs that meet regional priorities, whether fuel efficiency in resource-constrained environments or emissions reduction in health-sensitive areas. This approach supports scalable, evidence-based transitions to sustainable cooking solutions in Cameroon and similar contexts.
