As part of the World Cleanup Day and the environmental campaign #EUBeachCleanup, about 150 participants on the right bank of the river, including diplomats and employees of the Embassies of European countries, Asia, Africa, America as well as various UN agencies and other international organizations, cleaned the bank of the Yesil River from garbage.

As a result of this eco-event, a teleconference was organized with the UN Office in New York and Astana. At the end of the event, participants took part in a flash mob - they lined up on a map of Kazakhstan, which symbolized the participation of the entire country in this event.
