What kind of air are you breathing?
You can monitor the air quality in the Helsinki metropolitan area and Uusimaa in real time. Our map service shows the air quality where you are right now or where you are going. You can also check how the air quality changes over the next few hours.
The air quality in Finland is good by international comparisons, but air pollutants can reduce the air quality here as well from time to time. In the Helsinki metropolitan area, the air quality is reduced by street dust, traffic exhaust gases, air pollutants transported from elsewhere, dust from construction sites, and wood burning in detached house areas.
Up-to-date and comprehensive information on climate change is needed to enable sustainable urban life. We provide information on how residents can make a difference with their choices, as well as on how the region has succeeded in mitigating climate change and adapted to the changes it causes.Climate change Greenhouse gas emissions Climate-friendly life
Regional geographic information
Do you conduct planning or research work in which geographic information matters? Geographic information is being used more and more today, both at work and in leisure time. That is why we at HSY want to provide geographic information covering the Helsinki metropolitan area to both city authorities and ordinary citizens as open data. For those doing expert and planning work, we also offer customised register and map materials subject to licence, as well as information services.
In addition, we produce various information products about jobs, commuting, housing, lot reserves and monitoring. On our website, you can explore interactive graphs as well as more traditional reports on the above-mentioned themes.
Information for urban planning
Urban planning creates the conditions for a good and healthy urban environment. We provide urban planners with versatile information on the region’s development and the consideration of climate goals and air quality in planning.
