16. SNV Clean Cookstoves Programme Mekong
• 2015-2019
• Cambodia, Laos and Vietnam
• 120,000 clean cookstoves; 46,000 in Vietnam
• Market development approach: Result-based finance incentive
through the stove auction.

17. Market Study – 2/2016
• 70% of rural population use
traditional cookstoves such as iron
bar stove.
• Potential market of 12.8 million
HHs.
• Most results from project
interventions are successful but not
sustainable in long term.
• Private sector has many challenges:
products’ quality, behavior change
barrier, limited management
capacity and financial constraints.
