The novel sars-cov-2 virus was first found in humans somewhere in december 2019. more than half a year later, the virus has spread all around the world causing the worst global pandemic in over a century. its impacts have gone well beyond the disease, as the unstable socioeconomic situation resulted in the dubbed coronavirus great recession, reaching the maritime industry, as well. this master’s thesis assesses the impact of covid-19 on maritime traffic and the related emissions within a 30 nautical mile range around barcelona. the study uses real-time ais-acquired data, from march to july 2020, through a receiving unit located at the barcelona school of nautical studies (upc-barcelonatech). emissions were computed following the steam v.2 model developed by jalkanen et al. in 2012. results found that during the strictest lockdown days, vessel traffic increased by +1.8% in the area, in spite of a reduction in -8.8% in the number of calls at barcelona. this together with a reduction in the average speeds of vessels can be explained due to changes in the way vessels operated owing to the ongoing uncertainties. concerning emissions, values were also above the average. passenger vessels were responsible for up to 45% of total emissions, whereas they represented just 17.2% of total traffic. moreover, maritime traffic was found to have an important impact in daily variations of major air pollutants within the city, especially with regards to so2 and nox emissions.
