Clean Cookstove Research
According to the World Health Organization, cookstove smoke is a major contributor to indoor air pollution in developing countries causing approximately 2 million premature deaths annually and a wide range of illnesses.
Nearly half of the people in the world still depend on the burning of biomass (wood, charcoal, crop residues, and dung) and coal in rudimentary cookstoves or open fires to cook their food. People in developing countries, primarily women and children, are exposed to smoke with high concentrations of pollutants such as fine particles composed of toxic compounds.
Health studies show that exposure to cookstove smoke contributes to a wide range of illnesses such as pneumonia and low-birth weight in children, lung cancer, chronic obstructive pulmonary disease, blindness, and heart disease in adults, especially women who are disproportionately exposed in their homes.
As part of the Global Alliance for Clean Cookstoves , EPA is an international leader in clean cookstove research and provides independent scientific data on cookstove emissions and energy efficiency to support the development of cleaner sustainable cooking technologies.
Laboratory testing is being conducted at EPA's cookstove test facility in Research Triangle Park, NC. The facility has state-of-the-art measurement capabilities to characterize emissions of gases and aerosols, including toxic air pollutants, greenhouse gases, and black carbon.
Studies are conducted using multiple stoves and fuels tested under varying conditions to simulate operating conditions found in the field. EPA also sponsors and supports field testing.
Cookstove technologies are selected for testing based on specific criteria including: quantity in use, existing test data, potential market, need for baseline data, fuel availability, unique features, innovation, and partner needs.
EPA's research is making a significant contribution to providing cleaner cookstove technology throughout the world.
- As part of this effort, EPA supports development of standard laboratory testing methods and protocols designed to be representative of actual stove use in the field. Standards can provide incentive for stove developers to innovate and improve stove performance.
- The work is supporting the Global Alliance for Clean Cookstoves , which has a goal to foster the adoption of clean cookstoves and fuels in 100 million households by 2020.
- Investors, donors, and governments are seeking out the independent data to make decisions about clean cookstove programs
- The science is providing information to cookstove developers and manufacturers to advance clean cookstove technology.
The scientific contributions by EPA are:
- Improving the health of people in developing countries
- Addressing environmental problems with cookstoves such as deforestation when wood is sought for burning
- Addressing emissions of black carbon and greenhouse gases that contribute to climate change.

As part of PCIA's integration with the Global Alliance for Clean Cookstoves, the PCIA website has transitioned to a legacy website. The resources that were produced over the past 10 years of the Partnership are still accessible on this website. However, the content will no longer be updated as of June 1, 2012.
