SUSTAINABLE CITIES START WITH GREEN

Grey fades, green rises. Sustainable city examples prove it: rooftops become oases, walls begin to breathe, streets burst with life. Urban greening is no trend – it’s nature at work. Inch by inch, meter by meter, mile for mile, we reclaim the city. We replant the planet.

Urban greening expertise

Since 1996 global experience in green roofs, walls, and ground covers for healthier, greener cities.

Proven green impact

Our greenmapper shows real, measurable impact on air quality, biodiversity, cooling, and water retention.

Reclaiming urban space

We transform walls, roofs and streets into living ecosystems that boost urban life and climate resilience.

our solution

A greener urban landscape

Across the world, cities are heating up, flooding more often and losing vital biodiversity. Urban greening is no longer optional, it’s essential. By bringing nature back into built environments, we cool overheated streets, absorb stormwater, and give space to pollinators. Greener cities mean healthier people and stronger resilience to climate change.

They monitor the entire system remotely. If anything is wrong, they’ll call, “Please have a look at that.” It works great.

How will you green your city?

Every roof, wall or street can play a role in urban green. Imagine your own surroundings: where could nature return? A rooftop garden, a green façade, or more biodiversity in public space? The change starts with one step – what would yours be?

GREENING VERTICAL SPACES

Green walls, such as those from Sempergreen, are transforming urban spaces into sustainable oases. As a core part of Urban Greening, they directly address the challenges of urbanization. In cities with limited ground space, these vertical gardens offer a clever solution. They improve air quality by filtering fine dust and absorbing CO2, and they combat the urban heat island effect by insulating buildings. This insulation also lowers energy costs and increases comfort. Furthermore, green walls boost biodiversity by providing habitats for bees, butterflies, and birds. This makes cities not only more functional but also more beautiful, enhancing people’s well-being.

LIVING ROOFTOPS FOR YOUR CITY

Sempergreen’s green roofs transform rooftops into living ecosystems. They are a key component of the Urban Greening movement, offering an effective solution to the challenges of urbanization. These systems directly help increase biodiversity by providing a habitat for bees, butterflies, and birds.
Next to that, green roofs contribute to reducing the urban heat island effect. By insulating roofs, they lower urban temperatures and decrease energy costs for cooling. They also function as a natural water buffer, slowing down rainwater runoff and reducing the risk of flooding. All of this makes cities more sustainable and liveable.

SUSTAINABLE GROUND SOLUTIONS

Green groundcovers are transforming urban areas into vibrant landscapes. They offer an effective, low-maintenance solution to the challenges of Urban Greening. These ready-made mats contribute directly to a more sustainable environment.
They help increase biodiversity by creating habitats for pollinators and other insects. They also reduce the urban heat island effect by insulating the ground and roofs, which lowers temperatures and saves energy. The groundcovers also act as a natural water buffer, regulating urban water runoff and reducing flood risks. This makes cities greener, healthier, and more resilient.
Our ready-made ground cover transforms tramways into vibrant green havens. The system, which uses 80% less water than grass, reduces noise and heat, contributes to biodiversity, and improves air quality in busy cities.

Everything about urban greening

Find answers to the most common questions about how green roofs and walls improve urban greening, comfort, and energy savings. 

What is urban greening?

Urban greening means bringing nature back into the built environment. Think of green roofs, living walls and green public spaces that make cities healthier and more resilient.

Why is urban greening essential for cities?

It helps combat heat stress, reduces flooding, cleans the air and boosts biodiversity. Greener cities also improve people’s wellbeing and strengthen resilience to climate change.

How do green roofs and walls contribute to urban greening?

They cool buildings, retain rainwater, absorb CO₂, and provide space for plants and pollinators — turning grey surfaces into living ecosystems.

What impact can urban greening have on communities?

Greener streets and buildings create more attractive neighbourhoods, increase property value, and foster social interaction while offering natural places to relax.
