This project started as a grassroots movement by Hunter’s Bar Infant School (HBIS) in Sheffield when they were seeking to actively help to protect children from air pollution. HBIS led a fundraising campaign that, in collaboration with the University of Sheffield, provided the base to create a green barrier in their playground. The NBS is part of a bigger study called BREATHE that provides the science behind the project, which involves the design of the green barrier, the assessment of its impacts and a feasibility evaluation for installing green barriers in other schools in Sheffield and in Buenos Aires.

The 16-storey EnBW Administrative Complex and planned office district in Stuttgart's industrial area of Fasanenhof has three wings and a high-rise for about 2,000 employees on the 35,000 square meter sites, with many extensive green roofs and usable intensive roofs over underground parking. With the new office complex, EnBW wanted to create a modern and pioneering work environment for its employees. Different green system solutions were used on the project including a "Natural Roof", "Garden Roof", "Public Roof" and "Landscape Roof", with both extensive as well as walk-intensive plantings. The resulting green roofs offer respite and recreation for employees and visitors. [ref 1, 2]

The field is a 3.5 hectare of grassland, grazed by horses for over 20 years. After it fell vacant in early 2011, a group of local residents (“The Field Group”) negotiated a community lease with its owners, City of Edinburgh Council, with the aims of creating an orchard, creating/restoring semi-natural habitats and encouraging its use for quiet recreation and informal education. Members can volunteer their gardening labour or donate money. They can then participate in a garden run for the community – whether to pick the vegetables, learn fruit-growing, help to keep the chickens or just enjoy the space. [ref 1, 2]

Hanken School of Economics has placed green walls on its campus in Helsinki. The walls are placed in libraries and group rooms where students spend long periods of time to provide better air quality (ref, 2). The NaturVention (now known as Naava) patented active green walls are claimed to filter air 100 times more effectively than regular indoor plants (ref. 3). With pure and fresh Naava air, it is claimed that people can focus on their day, while Naava takes care of their air (ref. 5).

The reduced green space in cities and the declining level of unstructured physical activity affect especially children as major developments in the immune system occur during the first years of life. Interacting with nature also increases perceived well-being and promotes environmental responsibility. The KOTA-project was funded by Helsinki Metropolitan Region Urban Research Program and the University of Helsinki conducted the study. KOTA examined how greening of kindergarten yards affects children’s health and well-being in the urban environment. Six kindergarten yards were transformed and a control group of non-modified kindergartens was used. The project extended beyond Helsinki, with the transformed sites being not only in Espoo (part of the Helsinki Capital Region). (ref. 1).

Situated on an area of 52 acres, Father Collins Park incorporates many sustainability-focused features and has won a number of awards. Over 1200 trees and 2000 native saplings were planted to help integrate the existing woodland, maximise biodiversity, and vastly increase the ecological value of the park. Also, wetland areas were created to filter and clean the water in the park as part of a recycling system that replenishes and helps clean the lake and water features. The wetland areas mimic the characteristics of natural wetlands and create a special ecosystem that encourages greater biodiversity in the park. (Ref. 1)

To test the newly developed Green Factor Tool for the City of Helsinki, with a focus on water management, two test sites (ätkäsaari pilot block and the three model yards in Kuninkaantammi) were created at residential blocks in Jätkäsaari and Kuninkaantammi. The tool itself is an Excel interface that calculates the quantity and quality of the city's green spaces per unit of area, It is part of the larger iWATER (integrated stormwater management) project (Ref 2). Specifically, after testing it on these two pilot sites, it is to support land use planning processes by providing a way to account for the quantity and quality of green space. The project aimed to analyze the cost-benefit of implemented sustainable stormwater solutions, compile stormwater-related planning tools as well as increase and strengthen the capacity of cities to work with stormwater issues (ref. 2).
One of the key objectives of developing the green factor method was to create green urban environments that have social value. Also, functionality was the second most important and cityscape (or landscape value) was the third most important category in green factor scoring.

The Royal Society for the Protection of Birds (RSPB) ran a project to turn Belfast into the first-ever “Swift City”. The Belfast Swift City project aimed to bring nature back to the city and protect the swifts (ref 1). The aim was to find out where the birds are nesting, so work can begin to protect them. Additionally, there was said to be potential for the creation of community gardens in the area of residential buildings undergoing regeneration to aid this project. (Ref 2). As thousands of swifts migrate from Africa and nest in crevices in buildings, nesting boxes were put in a few locations like the parliament building to attract more swifts. (Ref 4)

In 2017, the municipality of Sintra approved the municipal Solidarity Gardens Program, which aims at enabling the inhabitants of Sintra to "value solidarity and, in some way, value natural resources" (ref.4).
This intervention aims to create small gardens in urban areas. Not only as a tool for subsistence for families in situations of social vulnerability but also to generate access to areas that tend to deteriorate, through correct management and profitability of resources. Eventually, the NBS aims to promote actions for the implementation of sustainable urban development, focused on strengthening family and local agriculture (1)

In 2011, the Great Lines Heritage Park was formed by connecting the Great Lines, Lower Lines, Inner Lines, Forst Amherst and Medway Park together. To do so, a former military area was transformed. The intervention connects the heritage towns of Chatham and Gillingham and the Chatham Waterfront. By connecting the heritage of the town and the waterfront, the project aimed to emphasize both these aspects of the area, but also to improve visitors' access and be a habitat for a number of species (Ref 2). The area has been created from a site that is of international heritage significance. The park is located within the Thames Gateway priority housing area, Europe’s largest regeneration project (ref. 3).
