South Korea is holding a wide range of events for tomorrow's second annual International Day of Clean Air for blue skies.
The foreign ministry on Tuesday will hold an international forum on air pollution available online.
The environment ministry this month on social media is hosting what it's calling a race event online and a contest to sing a campaign song, while a number of local governments are hosting forums and talk shows.
The occasion will be also celebrated at UN Headquarters in New York and at the UN Environment Programme in Nairobi.
September 7th was designated the day of clean air at the UN General Assembly in 2019.
The idea was proposed by South Korean President Moon Jae-in at the UN Climate Action Summit.
