"By working together, we can create a future where health and environment are at the centre of sustainable development." – Regional Director, WHO Office for the Western Pacific.

The mandate of WHO’s environment and health programme is to support Member States in improving health outcomes linked to environmental risks including:

  • unsafe water and inadequate sanitation;
  • poor air quality (indoor and outdoor);
  • exposure to toxic, hazardous waste and chemicals; and
  • climate change.

A key emphasis is on enabling more collaboration between health and environment sectors. WHO aims to enhance capacity in countries through regional networks of experts, sharing of good practices among countries, research, policies and action on environmental and occupational hazards to health, and beefing up of environmental surveillance and information systems.

Air pollution in the world: real time air quality map

  • View the interactive map here
    Worldwide, outdoor air pollution causes more than 3 million premature deaths each year. While some cities have already reached hazardous levels of air pollution – such as Delhi, India where smog practically covers the city daily – others are coming dangerously close. This new interactive map presents most of the world’s air quality in real time. (Linda Poon, The Atlantic Citylab)
