A map of the city showing trends in the condition and development of urban greenery. Individual areas and trees are color-coded according to trend: thriving, resilient, stable, vulnerable, and endangered. Prosperous and resilient greenery is concentrated mainly in continuous green belts, parks, and forest edges, while vulnerable and endangered areas are more common in densely built-up areas and along major roads. A legend of trends and a scale of 0–500 m are included.

UpGreen
Tree Productivity

Understand how well your trees are actually performing, based on chlorophyll and seasonal photosynthetic activity measured from satellite time series. UpGreen Tree Productivity helps you spot underperforming trees early and protect the cooling and carbon benefits your city relies on.

Close-up of colourful townhouses along a canal in central Copenhagen, with no visible greenery or street trees – highlighting the limited canopy coverage in dense urban areas flagged by the UpGreen analysis as a priority for future greening.

Map of the city with an overall assessment of the condition and resilience of urban greenery. Color-coded areas distinguish stable and more resilient parts of greenery in shades of green and more vulnerable areas in shades of yellow. More resilient zones are mainly located in outlying districts and near contiguous forest areas, while more vulnerable areas predominate in central and densely built-up parts of cities.

Copenhagen (Denmark)
UpGreen analysed approximately 280,000 trees across the city. Results show that around 20 percent of trees have below average productivity, indicating reduced photosynthetic performance and a higher risk of declining cooling and carbon benefits, especially in central and coastal districts.

Lisbon (Portugal)
The analysis covered 306,834 trees with crown areas larger than 30 m². Results reveal widespread reduced productivity during summer, driven by water scarcity, with many trees closing stomata to limit water loss, directly lowering cooling capacity and carbon sequestration across most of the city.

Kuřim (Czech Republic)

UpGreen assessed 16,916 trees within the city. The results show clear differences in productivity between neighbourhoods, highlighting trees that underperform despite low visible stress, providing an early signal for targeted maintenance and renewal planning.

UpGreen: measuring tree health, equity and climate benefits. Tree by tree, citywide. Using satellite data.

UpGreen identifies and evaluates trees across the city using satellite data and advanced modelling. We map tree crowns and assess key indicators that determine whether your greenery is thriving, cooling the city, sequestering, or silently declining. For the price of 10 cents/one tree.

More about UpGreen

What is tree productivity, and how we measure it?

In UpGreen, tree productivity shows how actively a tree is growing and photosynthesising. It reflects chlorophyll levels and leaf performance, making it a reliable indicator of tree vitality and overall health.

We measure productivity using satellite time series data that track vegetation activity throughout the growing season:

For each individual tree, we analyse satellite signals and create a smooth seasonal growth curve.

We identify the main growing period and calculate how well the tree performs over the season.

The shape of the seasonal curve also helps distinguish between broadleaf and conifer trees.

The result is a clear, comparable measure of how well each tree is actually performing, not just how green it looks on a single day.

Let's talk

Map of the city with an grid assessment of the condition and resilience of urban greenery. Color-coded areas distinguish stable and more resilient parts of greenery in shades of green and more vulnerable areas in shades of yellow. More resilient zones are mainly located in outlying districts and near contiguous forest areas, while more vulnerable areas predominate in central and densely built-up parts of cities.

Why should you know your tree productivity?

Because not all green is healthy.

Productivity helps reveal trees that look fine visually but are already underperforming.

Because productivity underpins benefits people feel.

More chlorophyll means more photosynthesis, which supports cooling, carbon sequestration, and overall vitality.

Support climate reporting and funding narratives.
City level totals and district breakdowns can be used in reporting, project justification, and grant documentation.

Compare areas fairly.

Aggregation by grid and administrative units shows where carbon storage is concentrated and where it is missing, which supports planning and targeting.
