Carbon Funding for Widespread Adoption of Improved Cookstoves

About the Implementing organization

Name: Instituto Perene

Country: Brazil

Year of establishment: 2006

Type of organization: Community-based association or organization, Legally recognized non-profit status


The solution is to enable thousands of rural households to substitute their old, smoky stoves with efficient cookstoves by subsidizing the cost with revenue from the sale of carbon credits. This is a pioneering initiative, and to date, the only cookstove project in Brazil to harness carbon financing. When Instituto Perene first identified the need for cleaner cooking technology, the team developed an appropriate stove design with the help of local builders and cooks. The result was a robust, built-in model equipped with a chimney and durability of 10 years. Villagers were enthusiastic about obtaining the new stove, but the price was out of reach for the local population, which is among Brazil´s poorest. The answer came in the form of a partnership with the Brazilian company Natura, which purchases carbon credits to offset its corporate emissions. The revenue from the sale of the credits is used for construction and monitoring. It is important to note recipients contribute approximately 20% of the stove cost, either in cash or in-kind (bricks and cement), which helps ensure their commitment to proper maintenance. Instituto Perene carried out all steps of the carbon offset project, from local stakeholder engagement to non-renewable biomass studies, quantification of emissions reductions and monitoring of social and environmental impacts. External auditing, project validation and carbon credit issuance is performed by the independent auditor The Gold Standard.

Environmental Impacts

The Efficient Cookstoves program has a positive impact both on local air pollution and global climate change. To date, 157,800 tons of carbon credits have been contracted, of which 36,768 tCO2e have already been issued by The Gold Standard Foundation, an internationally-recognized certification body based in Switzerland. The stove substitution results in a reduction of fuelwood use of approx.14,000 tons/year. This directly reduces pressure on the surrounding forests and wildlife habitat, from which communities extract firewood. The Atlantic Forest has a high species diversity, many of which are endemic, but this tropical biome is severely threatened by overuse, with less than 9% of its original vegetation remaining - it is listed by Conservation International as one of the world's 25 Biodiversity Hotspots.

Sustainable Development Impacts

As Secretary-General-Designate of the United Nations António Guterres pointed out "Clean cooking impacts multiple Sustainable Development Goals and must play a central role in our work to ensure the realization of human needs and fundamental rights". Stove substitution is a direct climate action as it reduces greenhouse gas emissions and helps protect forest resources. The program has generated 36,768 tons CO2e of certified VERs (Voluntary Emissions Reductions) to date, with an additional 120,000 tCO2e under contract. The 7,000 stoves installed so far are benefitting 26,600 people across 491 communities. Health benefits are reported by 87% of cookstove users, with the main points being less respiratory discomfort and decreased redness and stinging in eyes. General cleanliness of the kitchen is also much improved, with walls, ceilings and cookware free of soot.


Instituto Perene has steadily increased the scale of operation in Brazil. Perene began disseminating cookstoves in 2008, testing models in six rural homes. With a US$5000 grant from CARE Brazil, a consultant from Aprovecho Research Center was hired to help fine-tune the stove model and make it the most efficient possible. From this start-up phase, the carbon project was formatted and the first 1,000 stoves were built under contract beginning in 2009. Two more contracts and 6,000 more stoves have since been added. The work is on-going, with approximately 250 stoves/month being built. The stove model is very robust and built to last 10 years, providing a durable answer to the problem of rudimentary, inefficient open-fires. The demand for this efficient cookstove is enormous, with an estimated 50,000 families still to be served in the immediate region, and over 3 million households in Brazil alone.


An estimated 3 billion people worldwide depend on biomass fuel for daily cooking and heating, according to the World Health Organization. To meet this need, a broad array of technical solutions and financing mechanisms will have to be employed. Instituto Perene believes that the framework it has developed to fund the dissemination of efficient stoves through carbon financing is a highly replicable solution. Instituto Perene is looking for partnerships to replicate this cookstove program experience, offering our expertise in carbon-financing and grassroots technology development, including establishing Community Agent networks, performing temporal analysis of satellite imagery to assess biomass resources, systematic identification and recording of stove installations, rigorous monitoring of impacts,and the step-by-step process for project registration, validation, verification and certification by an independent, third-party.
