National Air Day was established in 2019 and is celebrated annually on April 12, with the aim of reflecting on the importance of the air we breathe and the challenges we face in preventing its degradation. This day emerged as a response to growing concerns about air pollution and its impacts on public health and the environment. Its creation seeks to raise awareness among the population and policymakers about the need for effective measures to reduce pollutant emissions and improve air quality.
Currently, air pollution is the leading environmental cause of death worldwide. According to the World Health Organization, it is responsible for around 7 million premature deaths every year. Prolonged exposure to atmospheric pollutants is associated with respiratory and cardiovascular diseases, as well as developmental problems in children, making coordinated action to address this issue urgent.
In Portugal, several academic and scientific institutions have been conducting research in the field of air quality, contributing to a better understanding of pollution impacts and to the implementation of more sustainable solutions. The Centre for Environmental and Marine Studies (CESAM) at the University of Aveiro stands out in this area, being one of the leading research centers on air quality in the country. CESAM researchers work on the development of predictive air quality models, pollution monitoring, and the definition of strategies to mitigate its harmful effects.
A survey on Portugal’s involvement in European air quality research projects (CORDIS platform) revealed that, out of a total of 92 projects, the University of Aveiro leads with participation in 10 funded projects in this area, followed by the NOVA University of Lisbon with involvement in 4 projects.
These figures reflect the ongoing effort of Portuguese scientific institutions to address the issue of air pollution and contribute to improving the quality of the air we breathe. However, this alone is not enough — a collective commitment to research, public awareness and engagement, and the implementation of effective policies is essential for a healthier and more sustainable future for all.
CESAM carries out cutting-edge research in the field of air quality through its RC3 – Oceanic and Atmospheric Modelling cluster. This research cluster focuses on air quality monitoring and forecasting, studying its sources and impacts, and defining strategies for its mitigation. The cluster’s interdisciplinary approach enables CESAM to actively contribute to the development of public policies.
