Consulting
Our experienced team offers consultancy services in air quality, air pollution, and climate change. We provide a wide range of solutions to governments, regional and local authorities, organizations, and European agencies.
We support the European Environment Agency and the European Commission in various aspects of air quality management. Additionally, we advise countries and regions on the implementation of European Directives.
Enviromental monitoring
We carry out air quality studies using passive samplers and other advanced techniques to analyse pollution in both indoor and outdoor environments. We provide realistic solutions based on scientific evidence and tailored to each setting.
We support the management of air quality networks, including the implementation and data management of hybrid networks with low- and mid-cost sensors. Additionally, we handle the validation of sensor data to ensure its reliability.
Furthermore, we offer installation services for weather stations to complement environmental analysis.
Interpretation and analysis of data
“It is as important to have equipment to measure air quality as it is to validate and interpret the data that this equipment provides us.”
4sfera specializes in the analysis and interpretation of environmental data. We apply different techniques to deepen our environmental knowledge. Using official air quality (QA) data, sensor data, modeling software and other sources of information, we conduct assessments for local, regional and/or European assessments…
Development of IT Solutions
We develop mobile applications, websites, and digital tools to facilitate the management and communication of air quality data. Our intuitive systems make this information more accessible to the public and inform sensitive groups about pollution levels.
By leveraging the potential of mobile technology and digital tools, we enable more local and direct communication with users.
We offer optimized solutions through efficient knowledge management and the innovative application of cutting-edge information technologies.
Public Health
Air pollution is a public health problem. In recent years, the majority of the European population living in urban areas has breathed in polluted air, which exceeds the limit values recommended by European directives and the World Health Organization. Exposure to poor air quality is estimated to cause some 400,000 premature deaths a year in Europe (EEA, 2020).
Climatic change
Air pollution and climate change are related. Various air pollutants are also climate force, which can have a potential impact on the climate and global warming in the short term. Because greenhouse gases and air pollutants share the same sources of emissions, the benefits can be derived from limiting one or the other emissions.
The impact of climate change on other air pollutants, such as particulate matter, is less certain. The response of PM to climate change is more complicated than that of ozone due to the diversity of PM components.
