A guest lecturing was delivered for graduate students of the American University of Armenia, course "Humans and the Natural Environment" on 1 July 2021 by the National Ozone Focal Point Ms. Liana Ghahramanyan. As students were supposed to gain an overview of environmental principals and current environmental issues, to review key environmental issues including climate change, loss of biodiversity, nitrogen and phosphorous cycle disruptions, eutrophication, chemical pollution (including persistent organic pollutants, heavy metals, particulate, etc.), degradation of natural habitats (deforestation, grasslands change and wetlands drainage), and so on under this course, the case of the Montreal Convention and the global effort to restore the Ozone layer was demonstrated to them as the success story addressing one of the global environmental problems.

The talk included the science behind Ozone layer depletion and the global efforts in restoring it, as well as the work that was done on the international fora and how Armenia compared to the global efforts.

The National Ozone Unit of Armenia has been using the guest lecturing format as one of the forms of raising awareness on the problem since 2005.
