Clean Cooking
About 2 billion people cook over open fires - often indoors - using cookstoves. These cookstoves cause excessive indoor air pollution and carry broader climate impacts. Women and girls in Sub-Saharan Africa spend an average of 2+ hours per day collecting firewood as cookstove fuel, which poses additional risks.
