Can local waste management strategies act as an emergency brake on global warming?
In short: Mohamed A. Sultan explains how African cities are addressing methane emissions from burning landfills. By diverting waste and supporting sustainable farming, these communities are reducing greenhouse gases while improving urban living conditions.
Methane is a potent greenhouse gas that poses a greater short-term warming risk than carbon dioxide. In many African cities, landfills frequently catch fire, releasing this gas into the atmosphere. Mohamed A. Sultan highlights how local initiatives are tackling this issue by diverting hundreds of tons of waste away from these sites.
These efforts extend beyond waste management by helping thousands of farmers transition to more sustainable agricultural techniques. This dual approach serves as a practical strategy to lower global temperatures while fostering more resilient and livable urban environments. This project is supported by The Audacious Project, a TED initiative focused on funding global change, and was presented at the TED Countdown Summit on June 16, 2025.
