“In the global race for clean air, everyone deserves to win.” — Antoinette Taus, UNEP’s Goodwill Ambassador

 

Clean air is a triple win: for our health, our climate, and our economy. Yet air pollution remains the second leading cause of death worldwide, claiming over 8 million lives each year and hitting the most vulnerable the hardest. 
UNEP’s Goodwill Ambassador Antoinette Taus reminds us: clean air saves lives, it is a right, and in the global race for air, everyone deserves to win.
 

From Space to Cities: NASA’s contribution to a cleaner air

To mark #CleanAirDay, NASA’s Research Physical Scientist Laura Judd explains how the TEMPO mission is helping to monitor and respond to air pollution.  

By combining satellite, aircraft, and ground data, the organization can provide science-based information to inform better decisions to protect health, guide cleaner air policies, and help communities plan for a healthier future. 

Clean Air, Shared Future: Tajikistan's youth advocates call for regional action on clean air

The Youth group on the protection of the environment calls for bold regional cooperation to address air pollution as a shared challenge that crosses the borders of Tajikistan and affects every aspect of life in Central Asia.
