Tiny Forest: we bring the forest back to the city

Transform grey spaces into lively, dense mini-forests. tgo plans, builds and maintains Tiny Forests as a complete solution – turnkey and scientifically grounded.

Scientifically grounded · Maintained long-term · Maximum impact

Four effects, one solution

Cities are getting hotter, heavy rainfall is becoming more frequent and companies need credible ESG measures. A tgo Tiny Forest is the answer – on a small footprint, with maximum impact.

Natural air conditioning

Up to 8°C of cooling through shade and evaporative cooling. Fewer heat deaths, a better quality of life in neighbourhoods and school playgrounds.

Sponge-city effect

Special soils with a humus-mulch system absorb water 32x faster than lawn. Relief for the sewer system and groundwater recharge.

Biodiversity hotspot

Up to 45 native species in the smallest of spaces. Wild bees, songbirds, hedgehogs, soil life – a Noah’s Ark on an urban scale.

On-site carbon sink

A 13-fold increase in soil carbon storage (SOC). Certifiable under ISO 14064 and the EU Carbon Removal Framework.

A Tiny Forest achieves more than you think

Scientifically proven, measured every year, documented in black and white.

A Tiny Forest needs just 100–200 m² – three parking spaces. And it delivers more ecological benefit than a park ten times its size.— Miyawaki research, confirmed in 40+ studies

Choose your path

Whether you are a local authority or a company – we have the right solution for your climate targets.

From grey space to living ecosystem

Tiny Forests turn unused spaces into natural air conditioning – tangible, measurable, lasting.

Scalable for any space

From courtyard to city-wide strategy – standardised, instantly calculable, turnkey.

What does your Tiny Forest cost – and what is it really worth?

Calculate in 60 seconds what your climate project costs and what value it generates over 30 years.

• ✓Complete planningSite analysis, soil screening, planting concept
• ✓2,000 plants35 native species, densely planted
• ✓3 years of maintenanceWatering, replanting, monitoring
• ✓Impact report & information boardAnnual documentation, on-site board

Scientific basis:

• CO₂ storage: 15 kg CO₂/m²/year (Miyawaki studies), valued at the EU ETS price (€0.18/kg)
• Cooling capacity: Avoided air-conditioning costs through local temperature reduction (€5/m²/year)
• Water management: Retention capacity based on the sponge-city concept (€1/m²/year)
• Biodiversity: Ecosystem services according to the TEEB study (€2/m²/year)
• Location value: Studies show a 5–15% increase in property value from green spaces

All values are conservative estimates based on peer-reviewed studies. The actual value may be higher depending on location and use.

Turbo growth through natural competition

Named after the Japanese botanist Akira Miyawaki. Through extremely dense planting of native species, the trees compete for light and grow 10x faster. After 20 years, you have a forest that would otherwise take 200 years.

• 🌱Dense planting: 3–5 plants per m² in a multi-layered structure (canopy, shrub and ground layer)
• 🪨Deep soil loosening: Preparation down to 60 cm with compost, mulch and organic substrate
• 🌊Sponge-city soil: Humus-mulch system for maximum water-holding capacity during heavy rainfall
• 🌳Multi-layered structure: A natural ecosystem with canopy, shrub layer and ground cover
• 🌿Native species only: A climate-resilient mix for maximum adaptation to the regional climate

40°C in the city. 32°C in the Tiny Forest. The difference? A forest on three parking spaces.— Measured cooling effect in urban Tiny Forests

More than just planting

Many plant trees and leave. We stay. Our all-inclusive, worry-free package secures your success in the long term.

Site check

We check utility lines, soil, water and access. You receive a clear go/no-go within 48 hours.

Miyawaki planting

3–5 trees/m², 20–45 species, deep soil loosening. A professional planting campaign with optional public participation.

3 years of maintenance

Watering, weeding, inspection. Replanting of up to 25% in case of losses. Until the forest stands on its own.

Monitoring & report

Annual KPI reports: survival rate, growth, biodiversity, soil infiltration – in black and white.

Trust through science

More than 40 peer-reviewed studies prove its effectiveness. Our partners are certified regional specialist firms.

Your complete package for real climate protection

From the first site analysis to the annual impact report – we are your partner for the entire term.

• ✓Turnkey implementationPlanning, soil, planting, information boards – all from a single source
• ✓3-year maintenance guaranteeWatering, weed control, replanting of up to 25%
• ✓Scientific monitoringAnnual KPI reports according to the tgo monitoring standard (A/B/C)
• ✓Carbon certificationISO 14064 / EU Carbon Removal Framework – audited by DEKRA/TÜV
• ✓Regional partner firmsCertified landscaping firms, tree nurseries, substrate suppliers

After 3 years, your forest stands – independently and permanently.

After just 20 years, a state that would otherwise take 200 years. And you get the data to prove it: survival rate, growth, biodiversity, soil infiltration.
