Deforestation · 2001–2025
Which has lost more forest, Moscow or Novosibirsk?
Moscow has lost more: about 243 ha of forest within 10 km of its center from 2001 to 2025, against 239 ha around Novosibirsk. 231 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: 2018, with 24 ha lost.
Worst year: 2008, with 23 ha lost.

Trees
Which has more trees, Moscow or Novosibirsk?
Novosibirsk has more tree cover: 20.0% of the land within 2 km of its center against 15.4% around Moscow, or about 55,543 trees against 44,849.
The dark mark is each place's canopy target: 30% of the land, raised where air quality is poor.

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
Moscow vs Novosibirsk: your questions answered
Is Novosibirsk cleaner than Moscow?
On air quality, yes, right now: Novosibirsk reads AQI 31 against 48, a gap of 17 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 5 days, on modeled daily averages, Novosibirsk averaged AQI 45 against 79, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Moscow and Novosibirsk today?
The advice is the same for both today. Air quality is satisfactory for everyone. Moscow reads AQI 48 and Novosibirsk reads AQI 31.
Which has lost more forest, Moscow or Novosibirsk?
Moscow has lost more: about 243 ha of forest within 10 km of its center from 2001 to 2025, against 239 ha around Novosibirsk. 231 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Moscow or Novosibirsk?
Novosibirsk has more tree cover: 20.0% of the land within 2 km of its center against 15.4% around Moscow, or about 55,543 trees against 44,849. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Moscow and Novosibirsk need?
Moscow needs about 42,519 more to reach its canopy target of 30%, and Novosibirsk about 27,772 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Moscow and Novosibirsk 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. Moscow is read from a nearby ground station and Novosibirsk is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Moscow vs Novosibirsk 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 10, 2026 and Sep 11, 2026), and the forest figures are published yearly.
