Daniel Ddiba, a researcher at the Stockholm Environment Institute, highlights the significant yet overlooked role of sanitation systems in global greenhouse gas emissions. With growing access to toilets leading to increased methane emissions, Ddiba emphasizes the need for innovative solutions to reduce these emissions and combat climate change. He advocates for better practices in sanitation management, like more frequent emptying of septic tanks and utilizing wastewater as a resource, which can contribute to both climate and energy crises.
