Achieving 30% urban tree canopy cover: best practices for European

UpGreen tree productivity grid map over aerial imagery, showing citywide spatial variation in tree productivity and vitality using green and yellow square cells, highlighting areas of higher and lower photosynthetic performance for urban greenery management.

Protect what already works: mature trees as the fastest canopy

Map from the UpGreen audit marking the locations of Lisbon’s highest-value trees with orange dots. These trees provide exceptional ecosystem services—such as cooling, carbon capture, and air purification—based on their size, health, and proximity to populated areas. The spatial distribution highlights priority zones for conservation and illustrates the application of tree value mapping in support of 3-30-300 urban greening targets.

Nature Based Solutions: Greening Europe’s Cities for Climate Resilience

Close-up of fresh water splashing over grass and soil, symbolizing the essential role of water in supporting healthy urban greenery. The image represents the importance of soil moisture and sustainable water management for trees to cool their environment, absorb carbon, and deliver crucial ecosystem services in cities.

Why cities are turning to satellite tree mapping

Illustration of a row of trees changing canopy density and colour, symbolising tree growth stages, seasonality, and long term urban greenery development.

Why every city needs a 3-30-300 green audit

ASITIS and the City of Slavkov win first place in

Award ceremony where ASITIS and the City of Slavkov u Brna are recognized for winning first place in the Czech Smart City Awards 2025 in the category Urban Planning and Environment.

Connecting the Dots: How Climate Impact Chains Help Cities See

Infographic illustrating the concept of Climate Impact Chains — showing how climate hazards (such as heatwaves or drought) trigger cascading impacts on urban systems, health, and the environment. The visual reflects ASITIS’s data-driven approach to understanding climate risks and supporting adaptation strategies for cities and regions.

3-30-300 Analysis in Slavkov: Green infrastructure as a key to

Map of Slavkov showing tree canopy cover in different neighborhoods and buildings meeting the 30 rule based on the 3-30-300 concept. The color scale represents tree canopy cover: 0-15% (red) – areas with low tree cover, 15-20% (orange) – areas with medium cover, 20-25% (yellow) – areas with higher cover, 25-30% (light green) – areas with high cover, >30% (dark green) – areas with very high cover. Buildings that meet the 30 rule (i.e., are surrounded by sufficient tree canopy) are marked in green, while those that do not meet this criterion are marked in red. The map includes a scale for better orientation.
