Urban releaf call for participation

The Riga Planning Region calls on local residents to engage in air quality measurements in Riga. This Urban ReLeaf campaign aims to facilitate evidence-based urban planning, aligning with the European Green Deal and Sustainable Development Goals.

Using sensors, the campaign seeks to gather data on air quality, temperature, and variability across different areas of Riga City Centre.  

PM2.5 pollution is a significant environmental hazard, causing premature mortality. In the European Union in 2018, 380,000 deaths were attributed to PM2.5 and 75,000 to Nitrogen Dioxide and Ozone combined. The ratio is even more pronounced in Latvia with 1,800 deaths attributed to PM2.5 pollution compared to 130 from NO2 and O3. 

Only two official monitoring stations in Riga measure PM2.5, the city has a need for additional data to support better decision-making. Therefore, from May 2024 to April 2026, 20 air quality sensors will be placed throughout the city, with a focus on PM2.5 pollution. 

The study aims to educate stakeholders and compare air quality between urban green spaces and high-traffic areas. Seven sensors will be placed in green areas, while thirteen will be installed in collaboration with residents across various locations in the City Centre. 

This opportunity is ideal for individuals interested in Riga’s air quality, or who are keen to learn about citizen science and those residing in or near the city centre. Participation involves filling out an application form, with thirteen residents being selected based on the suitability of proposed sensor locations and project requirements.  

For residents who will participate in the study:
⚈ Resident will receive one air quality sensor for installation in living / working place to measure pollution;
⚈ It will be necessary to fill out a questionnaire in which the macro and micro conditions of sensor placement are described in more detail;
⚈ It is desirable to ensure the operation of the sensor in the designated place for at least 2 years;
⚈ An opportunity to receive technical support will be provided in situations where there are problems with the operation of the sensor;
⚈ Technical problems with the sensors will require access to the sensor for repair.

Application deadline: March 18, 2024
