Air pollution is recognized as a public health and environment crisis. At the first session of the UN Environment Assembly in June 2014, air pollution was identified as a top priority that requires immediate action. Member countries requested UN Environment to support national efforts in addressing air pollution issues. Less than a year after, global health leaders came together at the World Health Assembly and recognized air pollution as an urgent public health crisis. They called for an enhanced global response to the adverse health effects of air pollution.
