An excerpt from the most recent issue of ISOFocus Magazine, this issue features new sustainable technologies and practices. Specifically, this publication covers household air pollution, a major concern for billions of people around the world, cutting lives short, damaging the environment, and putting huge burdens on global health.

Ranyee Chiang, formerly the Director of Standards, Technology, and Fuels at the Clean Cooking Alliance and now the Chair of technical committee ISO/TC 285 for Clean Cookstoves and Clean Cooking Solutions, explains why ISO standards are an essential ingredient.
