The EANET Awareness Workshop in 2021 was organized virtually on 6 September 2021, in partnership with the Republic of Korea. The event gathered over 200 participants from 16 countries and focused its discussion on international cooperation on acid deposition and air pollution. The workshop was aimed at increasing public understanding of regional acid deposition issues while reflecting on the work achieved by the EANET in the last 20 years. During the panel discussion on international cooperation, the panelists highlighted the EANET’s success, challenges, opportunities, and best practices. The Awareness workshop also featured a Special Session on “sharing experience from the Republic of Korea in acid deposition and air quality management”. The AIT RRC.AP supported the EANET Secretariat in organizing the event.
