In the past 6 years, SSM had worked with our partners to distribute approximately 860,000 units improved cook stoves in Southeast Asia. These improved cook stoves offer households subsidised or free clean cooking solutions, which are adapted to meet local customs and contexts. Comparing with local traditional stoves, SSM clean cook stoves have high thermal efficiency 50%+, which are estimated to reduce wood fuel consumption by 60% and carbon dioxide emissions by 80%. The impacts of improved cook stoves are wide-reaching and positive on income and health.
