The transformation of the world in a matter of months evinced the magnitude of the pandemic worldwide with a rising death toll and rapid spreading of infections from a previously unknown virus that appeared in Wuhan (China) in December 2019. Aside from the severe health and economic effects of the coronavirus, the environment has seen a few considerable improvements. Amongst others, air pollution and greenhouse gas emissions have dropped at a global level as countries struggled to contain the spread of the coronavirus. Although Greece has a long record of problems and challenges in its environmental policy, the pandemic seemed to have caused a significant decline in its air pollution levels. This is mostly manifested in the reduced average monthly concentrations of three air pollutants (NO2, PM2.5, and PM10) in 2020 compared to pre-pandemic levels. The aim of this paper is to assess Greece’s air quality by looking at three cities (Athens, Thessaloniki, and Patra) and comparing the average concentrations of NO2, PM2.5, and PM10 over the period 2019-2020.
