Improved cookstoves such as rocket and gasifier cookstoves have been shown to be more harmful to humans than conventional cookstoves due to the excessive presence of ultrafine air pollution particles, a new study has found.
In 2015, 85.6 million years of life were lost due to impairment due to indoor air pollution and resulted in more than 2 million early deaths worldwide. A big contributor to indoor pollution is domestic solid fuel burning used for cooking and heating.
