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.

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.

Adoption Study – 11/2016

Negative health symptoms felt by HHs: headaches, coughing,

stinging and watery eyes, difficult breathing.
