Replace Cookstoves Get Results

Reduce CO2 Emissions

Each stove installation reduces emissions by 30t CO2 yearly. We are installing 5000 stoves.

Remove exposure to smoke and heat

Our stoves have chimneys to move smoke away from workers’ eyes and lungs.

Combat deforestation

40 kg of firewood is saved per student per year. We serve over 2,000,000 students.

Proven method: Rocket Technology

The project reduces green-house emissions by installing fuel-efficient stoves to replace open fire cooking in school kitchens. The improved institutional stove reduces fuel consumption by introduction of an insulated combustion chamber which increases combustion efficiency and retains heat. It uses the well-proven rocket technology, which consists of an insulated elbow-jointed combustion chamber that increases combustion efficiency and retains heat while also raising the cooking pot to the hottest point above the flame. The institutional rocket stoves further increase heat transfer by having the cooking pot rest within a skirt.

With your involvement, we can sustainably finance the program through sales of ITMOs (Paris-Compliant Carbon Credits).


Front the capital expenses to install and maintain cookstoves in schools. They get their return on investment from sales of our high quality credits on the carbon market.

business agreement


Pay for emissions reductions to meet their climate obligations. The revenue pays for the materials, equipment and labour to deliver the program. As well as to reimburse investors.


The less capital we take from investors to cover costs, the more of the revenue we can dedicate to climate adaptation through the community benefit fund.
