A running track is being built in the center of Józsa, on Klastrompart. The one-kilometer-long running track will cross the Tócó stream in two places. Here, among the trees, on the banks of the stream, it will be possible to exercise in a natural environment, where the Green Sentinel will also watch over joggers.

The Citizen Science program continues: this time, more than 300 students at three locations learned about the operation of the Green Watch. The children learned how data is collected, what measuring instruments the system uses, and how the environment is examined. The importance of biodiversity was illustrated in an interactive presentation.

The Green Sentinel senors reported a significant increase in PM10 and PM2.5 particulate matter concentrations on 11 June 2025 between 02:00 and 04:00 am, due to adverse meteorological effects.

The Green Sentinel has expanded with a new community initiative: the Citizen Science program has been launched! The goal is to give the residents of Debrecen a closer look at how environmental data collection works and even allow them to participate in it.

The European Commission has recognized Debrecen's commitment to environmental protection: our city has been named one of the ten best candidates for the European Green Capital Award 2027. This decision further reinforces the knowledge-based, green approach that characterizes Debrecen's development.

The Environmental Control System, one of the priority measures of Debrecen's Environmental Strategy, the Green Codex, has been implemented, and the details of its operation were presented at a scientific conference by the university researchers and experts involved in its development. This marked the launch of the Green Sentinel, a short tutorial video of which can be found on its website here.

The Environmental Monitoring System monitoring station network has been completed and a public site visit was held on 30 January 2025. The press tour, which was attended by the Mayor, included a presentation to the press of the first completed Józsa Klastrompart complex monitoring station.

One of the 50 measures outlined in Debrecen's environmental program, the Green Code, is the creation of an Environmental Monitoring System. This Green Watch is unique in the country: it is an automated information and data collection, analysis and monitoring system developed by experts, operated and supervised 24 hours a day, which continuously monitors our environment.

The construction of the monitoring stations is progressing well. On 11 November 2024, the Board of Directors was informed about the progress of the works in the immediate vicinity of the Southern Economic Belt. The construction of the monitoring stations has reached the finishing line and the infrastructures are ready to receive the equipment.

Baseline monitoring is a prerequisite for monitoring and controlling changes in the environment, i.e. the precise assessment and recording of the baseline condition. Any changes that may occur in the environment can be compared to this. The baseline monitoring involves the assessment of surface water, groundwater, ambient air quality and soil conditions, and the associated baseline environmental a

How do we test the state of our environment? Complex and automatic samplers, quality control stations, probes and many other instruments support the work. Instruments and sensors provide continuous online data. Some instruments also take samples of our environment (air, aerobic and water samples), which form the basis for laboratory tests.

The Environmental Monitoring System consists of 16 complex monitoring stations and 2 surface water monitoring stations, forming a coherent system covering the whole city. The locations of the monitoring stations have been selected to be representative of larger similar areas.
