Smoke - indoor air pollution

The killer in the kitchen

Nearly four million people die each year as a result of inhaling lethal smoke from kitchen stoves and fires. Most of these deaths are a result of respiratory infections. Most victims are women and children under five.

More than three billion people worldwide depend on fuels such as wood, dung and coal to meet their basic energy needs of cooking, boiling water and heating.

Burning these fuels on rudimentary stoves or three stone fires creates a dangerous cocktail of pollutants. It is the poor who rely on the lowest grades of fuel and have the least access to clean energy.

  • 3 billion people still cook on open fires using wood, animal dung, crop waste or coal as fuel
  • Each year 4 million people die prematurely from diseases caused by inhaling smoke from indoor fires
  • Half the deaths from pneumonia of children under five are attributed to indoor air pollution
  • Over 1 million people die each year from Chronic Obstructive Pulmonary Disease (COPD), again attributed to exposure to indoor air pollution

Statistics from the World Health Organization

Practical Action have been involved in developing appropriate and affordable household cooking stove technologies for over 20 years in many countries in Latin America, Africa and Asia, in many areas of stove development and implementation.

Our experience and technical skills on this issue ranges from technology development, through to market support, awareness raising and gender and health issues in both urban and rural areas.

Scaling up to save lives

Practical Action works directly with those affected by indoor smoke to cut indoor air pollution and improve health. We also work with governments and other agencies to scale up this approach beyond our own projects.

Recently the Nepali government announced that all homes in Nepal would be smoke-free by 2017. And the Global Alliance for Clean Cookstoves aims to provide 100 million clean-burning stoves to villages in Africa, Asia and South America by 2020.

Practical Action continue to promote sustainable solutions to energy access and indoor air pollution, and move towards eradicating the killer in the kitchen.

Around the world, Practical Action's simple solutions are making a real impact on people's health and lives.
