Deforestation · 2001–2025
Which has lost more forest, Tampere or Turku?
Tampere has lost more: about 2,850 ha of forest within 10 km of its center from 2001 to 2025, against 1,620 ha around Turku. 1,440 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2020, with 260 ha lost.
Worst year: 2017, with 206 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Tampere vs Turku: your questions answered
Is Turku cleaner than Tampere?
On air quality, yes, right now: Turku reads AQI 36 against 44, a gap of 8 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 7 days, on modeled daily averages, both averaged AQI 17.
Is it safe to exercise outdoors in Tampere and Turku today?
The advice is the same for both today. Air quality is satisfactory for everyone. Tampere reads AQI 44 and Turku reads AQI 36.
Which has lost more forest, Tampere or Turku?
Tampere has lost more: about 2,850 ha of forest within 10 km of its center from 2001 to 2025, against 1,620 ha around Turku. 1,440 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Tampere or Turku?
Turku has more tree cover: 40.1% of the land within 2 km of its center against 38.2% around Tampere, or about 124,214 trees against 108,248. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Tampere and Turku need?
Tampere needs about 0 more to reach its canopy target of 30%, and Turku about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Tampere and Turku measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Tampere vs Turku comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 11, 2026 and Sep 6, 2026), and the forest figures are published yearly.
