Clear the skies for a thriving planet.

 


What’s clouding our future? Air pollution—the top environmental health threat—chokes lives, climates, and economies. “Invest in Clean Air Now” isn’t just a call—it’s a win for health and sustainability.

On thiS International Day of Clean Air for Blue Sky and every day in between, WMO’s on it: tracking trends with the Air Quality and Climate Bulletin, monitoring wildfire smoke, and mapping pollution hotspots. Cleaner air fights climate change, boosts crops, and saves lives.

Let’s cut emissions, power up renewables, and strengthen warnings—together, we’ll clear the skies for a thriving planet.

Annual meeting of the Joint Task Force on Health Aspects of Air Pollution (2025).

Image
The 2025 annual meeting of the Joint Task Force on the Health Aspects of Air Pollution gathered virtually 50 participants representing 27 Member States and 4 intergovernmental organizations to share information and updates or air quality and health and to review recent progress in the health risk assessment of air pollution under the United Nations Economic Commission for Europe Convention on Long-range Transboundary Air Pollution (UNECE Air Convention). Air pollution in an evolving context The Head of the WHO European Centre for Environment and Health, Ms Francesca Racioppi, opened the meeting by pointing to the increased attention to air quality following the Second WHO Global Conference on Air Pollution and Health (March 2025) and the adoption by the World Health Assembly of the Updated road map for an enhanced global response to the adverse health effects of air pollution (May 2025). The road map includes a voluntary target to halve the health impacts from anthropogenic air pol...

Healthy Indoor Air: A Global Call to Action..

Image
   Join global leaders, policymakers, scientists and health experts for Healthy Indoor Air: A Global Call to Action – the inaugural High-Level Side Event on indoor air quality, to take place on the sidelines of the UN General Assembly. Outline of session: High-level speakers from government, UN agencies, academia, healthcare, education, policy, sustainability, and industry will gather to s hare insights, experience, and diverse perspectives on how they are approaching indoor air quality , noting this is currently a gap in most public health frameworks. Airborne diseases (including those that cause pandemics) and airborne pollutants (like wildfire smoke and vehicle emissions) may be invisible, but they cause profound harm. With global populations spending ~90% of time indoors, buildings need to prioritise and guarantee access to clean, safe air. As climate change intensifies wildfires and the risk of novel pathogens increases, the need for research, policy, and action on IAQ ...

Smarter Feed, Stronger Genes, Healthier Herds: The Path to Lower Livestock Emissions.

Image
  Livestock methane represents 32% of all human-made methane emissions. Increasing productivity of livestock systems is a crucial lever to reduce emissions from agriculture. It increases the production of food while reducing the need for extra animals, and it paves the way for the development and adoption of groundbreaking methane-reducing technologies by farmers. Investing in groundbreaking solutions to reduce emissions from livestock and on productivity increases are crucial steps to achieve the emissions reductions from livestock we need. The Climate and Clean Air Coalition (CCAC), Clean Air Task Force (CATF), Spark Climate Solutions, and the Environmental Defense Fund are coming together to highlight the key pillars for optimizing productivity and reducing emissions in livestock: feed, breed, and animal health – the triple win. Through the lenses of multiple livestock stakeholders, we will highlight the opportunities and challenges on the path to sustainable intensification, ...
