It turns out the smell is the least of our worries when it comes to landfills.

In this talk, sustainability strategist Mohamed A. Sultan shares why methane gas, the odorless, invisible gas, is so dangerous for our health and our well-being.

Showcasing different examples of sustainable development projects across the African continent, he offers an alternative path towards a world with low methane emissions and shares why this is not only good for the planet, but good for people everywhere.

That was Mohamed A. Sultan at the TED Countdown Summit in Nairobi, Kenya in 2025.
