What Is Urban Greening & Why Is It Crucial for Your Business

Although our cities are growing by the day, they are suffering from a lack of green spaces. This can negatively impact the air quality and mental well-being of those who live in urban areas - almost 85% of the UK’s population - as well as contributing to the urban heat island (UHI) effect, where cities are much warmer than rural areas. 

Fortunately, this is an issue that many governments worldwide are looking to tackle through urban greening, and more sustainable urban landscaping is being installed across our cities to combat climate change. This article will explore the benefits of urban greening, common strategies to achieve it, and how we’ve contributed here at Scotscape. 

What Is Urban Greening?

By definition, urban greening is a public landscaping and urban forestry scheme that promotes mutually beneficial relationships between city inhabitants and their surrounding environment. In other words, it’s about changing our urban spaces from concrete jungles to green areas we enjoy spending time in, reaping the social, economic, and environmental benefits that come with this. Popular examples of urban greening include living walls, pocket parks, and micro forests - we’ll explore these in more detail later. 

Back in 2018, the Mayor of London, Sadiq Khan, set out an ambitious target of making London a zero-carbon city and at least 50% green by 2050. Urban greening has been instrumental in helping London take great strides towards meeting these targets, which would see the capital become the greenest global city. 

What Is the Urban Greening Factor?

The Urban Greening Factor (UGF) is a planning tool that assigns weighted “greening scores” to different types of vegetation and green infrastructure on a development site. This ensures a minimum, quantified level of greenery by comparing the site’s total greening score against a target factor value.

Urban greening projects are the practical application of the UGF framework; by installing green roofs, planting street trees, or incorporating living walls, site developers can accrue greening “points” based on the type, extent, and ecological value of each intervention.

What Are the Benefits of Urban Greening?

There are many benefits of urban greening, which is why so many projects in major cities such as London, Manchester, and Birmingham are getting involved. Let’s explore the advantages for the wider cities, the businesses within, and the people who live and work there:

Benefits for Cities:

• Reduces urban heat island effects through increased shade and evapotranspiration.
• Strengthens stormwater management by absorbing and filtering water runoff. 
• Improves air quality by trapping airborne pollutants, such as particulate matter.
• Supports urban biodiversity by creating natural habitats and ecological corridors.
• Creates a more resilient and attractive city for residents, commuters, and tourists. 

Benefits for Businesses: 

• Increases foot traffic and dwell time, as customers tend to stay longer in greener areas.
• Reduces energy costs through natural cooling and shading of commercial buildings.
• Strengthens business image through visible sustainability efforts. 
• Improves property value, since green buildings are more desirable. 
• Attract and retain employees who value healthy, attractive work environments

Benefits for People: 

• Promotes increased physical and mental well-being through access to green spaces. 
• Encourages outdoor activity and social interaction in safer, more inviting areas. 
• Improves respiratory health by lowering airborne particulates.
• Limits noise from motorways or other busy roads, since plants absorb acoustic energy.
• Reduces stress and anxiety, as green spaces create a positive emotional response.

What Are Common Urban Greening Strategies?

So, how is urban greening achieved? Here are some of the most common strategies that project planners use to help our cities become greener:

Living Walls

Living walls are vertical gardens fixed to the facade of a building, helping to make the most of available space in urban areas. Plain walls are transformed into plant-filled surfaces, often using low-maintenance greenery such as climbers and wall shrubs. These flexible installations improve air quality, provide insulation that can reduce heating and cooling costs, and create an aesthetically pleasing environment that’s attractive for all who see it.

Green Roofs

Green roofs are another popular urban greening strategy, replacing conventional roofing materials with a layered system of waterproofing, soil substrate, and vegetation. They are great for retaining rainwater, reducing building energy use through passive insulation, and offer a habitat for pollinators like bees and birds. On large scales, green roofs are a major contributor to a reduction in the urban heat island effect, helping to keep our towns and cities cooler.

Street Trees

Planting and maintaining street trees is one of the most cost-effective greening strategies. Trees provide natural shade that can lower pavement and road temperatures, intercept rainfall to reduce runoff, and filter airborne pollutants like dust. National sponsorship schemes, such as Trees for Streets, offer residents, businesses, and councils the opportunity to increase the number of street trees in urban areas.

Living Pillars

Living pillars are the application of planting to street lighting, offering a sustainable solution to the difficulties of planting in our concrete streets. They are solar-powered with recirculating irrigation methods, helping to recycle the water used within each living pillar. Whilst they are great for adding year-round visual interest, they are also successful at mitigating pollution caused by the “street canyon effect”, where pollution is trapped at street level.

Groundscrapers

Although our larger towns and cities are synonymous with skyscrapers, many urban planners are opting for groundscrapers; essentially, a skyscraper on its side. Groundscrapers integrate expansive, low-rise building footprints with green landscapes, combining horizontal architecture with open gardens or other eco-friendly social spaces. Offices, retail, and housing are woven into tree groves, water features, or small meadows to support biodiversity and increase outdoor enjoyment.

Pocket Parks

Pocket parks are another great example of urban greening, transforming underused or vacant areas, often no larger than a single building footprint, into a tiny public green space. Even small clusters of benches, plantings, water features, and children’s play features can boost livability within the area, provide informal gathering spots, and improve mental well-being. Their small scale makes them easy to install and maintain, offering an attractive option for local councils and developers to consider.

Micro Forests

Similar to pocket parks, micro forests use small spaces in urban areas to increase carbon mitigation, helping to deliver exceptional air quality and biodiversity benefits. They are grown using the basic principles of the Miyawaki method of afforestation, which emphasises the natural growth of forests through the use of native plant species. Through the correct ground preparation, this method can see trees grow up to 8 times faster than a conventional tree per year!

Community Gardens

Community gardens allocate plots of land to residents and businesses for growing fruits, vegetables, and flowers. These areas can strengthen social cohesion, offer hands-on environmental education for children and adults alike, and support biodiversity through pollinator-friendly plants. Community gardens don’t need to be large, making them ideal to fit between even the most built-up areas in the UK.

Rain Gardens

Rain gardens are shallow or dipped areas designed to receive water run-off from nearby building roofs and other impermeable surfaces. Planted with vegetation that can be waterlogged for up to 48 hours at a time, they slow and filter rainwater, reducing storm drain loads. Rain gardens can absorb up to 30% more water than a typical lawn, and the vegetation is attractive for insects, birds, and other nearby wildlife, increasing biodiversity in our urban areas.

Urban Greening in Practice

At Scotscape, we’re eager to play our part in urban greening projects. Commissioned by Shaftesbury Capital PLC, we were tasked with installing a living wall at 5 - 7 Carnaby Street, London, softening the impact of a new double-height roof extension. Carnaby Street is a busy and attractive area, so the project needed to deliver immediate impact, whilst also increasing biodiversity levels and absorbing pollutants. 

The installation involved a chevron tree planting design, inspired by the 60’s heritage pattern. All areas of the wall were covered by greenery, thanks to our bespoke planting panels, and we designed multiple zones to ensure the greatest control over the delivery of irrigation to all parts of the living wall.
