COVID-19 Pandemic Leads to Significant Emission Reductions in Aviation Sector

Strategic Insights -

The COVID-19 pandemic had a profound impact on various sectors, including aviation and travel, as travel bans and lockdowns led to a drastic decline in air travel. According to a study conducted by researchers at the Zonguldak Bulent Ecevit University, Turkey, the pandemic resulted in significant emission reductions in the aviation sector. The study aimed to investigate the Landing/Take-Off (LTO) emission changes at Turkish airports, and the findings were published in the journal Environment, Development and Sustainability.

The study revealed that total emissions of SO2, CO2, CO, NOx, NMVOC, CH4, N2O, and PM2.5 decreased in 2020 compared to 2019 by 49.8%, 49.7%, 41.0%, 52.6%, 40.0%, 33.8%, 49.8%, and 50.3%, respectively. The study also found that total CO2 reductions in the Q2, Q3, and Q4 periods of 2020 compared to that of 2019 were 87%, 50%, and 43%, respectively.

The researchers concluded that the main causes of emission reductions were travel bans in Q2 and changes in travel intention in Q3 and Q4. The study's findings contribute to both air pollution and tourism management research, highlighting the importance of understanding the underlying reasons for emission reductions in the aviation sector.

Key Takeaways:

  • The COVID-19 pandemic led to a 49.8% decrease in CO2 emissions in 2020 compared to 2019 at Turkish airports.
