Sustainable development diplomat, educator, activist

Innovative cooling solutions range from high-tech to low-tech, promising a sustainable future without warming the planet.

Transforming cities for cool involves more than technology; it's about creating equitable, sustainable environments for all.

By 2050, the demand for air conditioners is expected to surge to over 5.5 billion, increasing electricity needs for cooling by 50% by 2030.
