Urban Reforestation

Plant a tree in the greatest cities on Earth.

From New York to Tokyo, Paris to Singapore, CityCanopy runs urban reforestation programs that turn concrete into living canopy. One neighbourhood at a time.

Why it matters

Cities need trees more than ever

The world is urbanising faster than at any point in history. Without deliberate, large-scale canopy investment, cities become heat traps, air pollution zones, and mental health deserts.

๐ŸŒก๏ธ

Lower Urban Heat

A single mature tree can reduce surrounding air temperature by 2-8ยฐC through evapotranspiration. City streets with full canopy cover are up to 15ยฐC cooler than treeless equivalents.

๐Ÿ’จ

Cleaner Air

Urban trees absorb CO2, particulate matter (PM2.5), ozone, and nitrogen dioxide. One large tree can absorb 48 pounds of CO2 per year and produce enough oxygen for two people.

๐Ÿง 

Mental Health

Living within 300 meters of green space reduces stress, anxiety, and depression. Studies in London and Amsterdam show hospital admission rates for mental illness drop 12% near tree-lined streets.

๐Ÿ’ง

Stormwater Control

Tree canopy intercepts 30-40% of rainfall, drastically reducing runoff and flood risk. New York's urban forest absorbs 890 million gallons of stormwater every year.

๐Ÿ˜๏ธ

Property Value

Homes on tree-lined streets sell for 10-15% more. Research from Portland and Chicago shows mature street trees increase surrounding property values by $8,000-$12,000 on average.

๐Ÿฆ‹

Biodiversity

Urban trees create corridors for birds, insects, and small mammals. A single oak tree supports over 280 species of insects. Cities like Singapore have recorded 400+ bird species thanks to urban greenery.

Where we work

The world's great cities

Each city has its own climate, soil, culture, and canopy story. CityCanopy builds programmes tailored to the specific character and ecology of every urban landscape.

Our method

How we plant at city scale

Planting trees in cities is harder than planting in forests. Compacted soil, underground utilities, air pollution, and heat stress all need careful management. Here is our proven process.

01

City Assessment

We map existing canopy cover, heat islands, air quality, and soil conditions across every neighbourhood. Data drives every decision.

02

Species Selection

Native and climate-adapted species only. We match species to soil type, microclimate, and local biodiversity. No monocultures.

03

Community Planting

Local volunteers, schools, and city workers plant together. We train teams, supply tools, and run every event from permit to last shovel.

04

Long-Term Care

We monitor every tree for 3 years post-planting. Watering, pruning, pest management, and survival tracking keep the canopy growing.

Proven results

Trees don't just look good. They work hard.

Every CityCanopy tree is tracked from nursery to maturity. We measure canopy growth, carbon sequestration, stormwater capture, and community health outcomes. Impact is not a feeling. It's a number.

Singapore: the world's greenest city

Singapore has achieved what most cities only dream about: 47% canopy coverage in a dense tropical metropolis of 6 million people. The government has planted over 7 million trees since the 1960s, and the city's "City in a Garden" master plan continues to accelerate.

Singapore proves that density and green space are not opposites. Vertical gardens, rooftop forests, and Supertrees at Gardens by the Bay show what a city-scale commitment to nature looks like. CityCanopy programmes draw on Singapore's methodology worldwide.

The science

Not all urban tree programmes work

Most city tree-planting campaigns fail within five years because of poor species selection, inadequate aftercare, or a lack of community ownership. CityCanopy's approach is built to last.

๐ŸŒฑ

Native species first

Exotic species in unfamiliar climates struggle to establish and offer little to local wildlife. We prioritise indigenous species with proven urban tolerance.

๐Ÿชฑ

Soil before saplings

Compacted urban soils need decompaction, mycorrhizal inoculation, and organic matter before a tree can thrive. We prepare every planting site for 5+ years of growth.

๐Ÿซถ

Community stewardship

Trees planted by a community are watered and cared for by that community. Every programme includes a 12-month 'tree guardian' training course for local volunteers.

๐Ÿ“Š

Data-driven site selection

We overlay heat maps, air quality data, soil surveys, and demographic data to prioritise neighbourhoods with the highest need and the highest probability of canopy survival.

๐ŸŒง๏ธ

Infrastructure-conscious design

No tree within 3 metres of a water main. No shallow-rooted species above cable lines. Our city planning team works with municipal engineers before every planting.

๐Ÿ“…

3-year survival guarantee

Any CityCanopy tree that dies within 3 years of planting is replaced at no additional cost. Our 91% survival rate across all programmes means this is rarely needed.

๐ŸŒณ
"A society grows great when old men plant trees whose shade they know they shall never sit in."
Greek proverb

The best time to plant a city tree was 50 years ago. The second best time is right now. CityCanopy is running programmes across 12 cities today. Every tree you fund is GPS-tagged, monitored, and publicly reported for its full 50-year lifespan.

Join us. Plant a tree in a great city.

Individuals, businesses, and city councils all have a role to play. Whether you plant one tree or fund a whole neighbourhood, the canopy grows together.
