 The World Health Organization (WHO) estimates 1.5 million people die each year due to indoor air pollution. Simple interventions, like a chimney, can help improve the lives of millions.

Cookstoves, Air Pollution, and Health


 Cookstove Project Resources


 Cookstove Project Contact


​More than half of the world’s population relies on open fire cooking pits to meet basic energy needs. Indoor cookstoves can result in extremely high levels of indoor air pollution. Indoor air pollution is a phenomenon that kills 1.5 million people yearly on a global level. Improved stove designs have the potential to reduce indoor air pollution exposure; however, evaluations of improved stoves are limited.


The Nicaragua Cookstove Project started in 2007 by a group of undergraduate students at CSU who collaborated with a local non-profit group - Trees, Water, and People; a Nicaraguan cookstove manufacturing company - Proleña; and a woman's organization in Nicaragua, Casa de la Mujer. Together they were able to provide subsidized cookstoves that would replace their open pit fires to over 100 families in the community of El Fortín, Nicaragua. The undergraduate students, along with CSU faculty, developed an ongoing study which assessed the health improvements of the community as well as evaluated the improved smoke exposure from toxic agents such as carbon monoxide.

Cookstove Study in Honduras

In January 2013 a new study began to evaluate the impact of cleaner burning cookstoves on measures of cardiovascular health (blood pressure and markers of systemic inflammation) in Honduran women who currently cook over an open fire. The study will also evaluate the impact of the cookstoves on levels of carbon monoxide and respirable particulate matter (less than 2.5 micrometers in diamber). The study will take place near Copan Ruinas, Honduras.

Cookstove Intervention in Nicaragua

This project is a community cookstove intervention in a neighborhood called El Fortin, just outside of Granada, Nicaragua. The study will address a critical global environmental health problem by building community partnerships. This project is also contributing to the education and training of undergraduate and graduate students.

2008 Baseline Evaluation

The baseline evaluation of a population using traditional cookstoves was completed during the summer of 2008. The participating families then received the improved wood-burning stoves in August and September 2008.

2010 Return Trip

Students returned to El Fortin in December 2010 to perform exposure and health assessments to determine if the improved stoves had a positive impact on the participant’s overall health. Fundraising efforts are currently underway for future return trips. Please help fund this project with an online donation.

This project is a unique and valuable experience for the students, who use the project as an internship and/or receive research credits for their work. This study aims to involve undergraduate students, in applied and experimental research projects in this important area of global health and clean energy research.
