To make our city a cleaner place!



Monitor the air quality of the entire city and give its residents easy access to clearly structured and always up to date information.


Mission objectives

Our goal is to create a well engineered, weather resilient box, containing gas, temperature and pressure sensors that can easily be mounted on buildings, public transportation vehicles, bicycles etc. The data that they collect is presented on an interactive, user friendly map that shows in color the cleaner and the more polluted areas of the city which will inform people and involve them in the issue. This serves as a milestone to our ultimate goal- to make Sofia’s air cleaner.


The problem

The urbanisation in most of the world is creating new challenges for scientists and engineers. Pollution remains one of the most severe problems, causing a variety of health issues and affecting millions of people living in large cities.

According to the European Environment Agency, Sofia is the european capital with the most polluted air. The Bulgarian Environment Agency has an air quality monitoring system, however it is incomplete and shows data from only 13 sensors throughout the city and only displays the measurements above critical level. The awareness among citizens is low which causes negligence toward this very serious problem. We have created an ongoing online questionnaire from which the current results show that most of the people feel they are not well informed about the pollution levels in Sofia and have concerns towards the subject.
