The Restoration of degraded wetlands in Wolfschlugen (in the administrative district of Stuttgart) was conducted within the wider regional level of sustainable urban development to enhance resilience, protect the city from flooding, support sustainable development, and safeguard biodiversity. Ditches and craters line the 700 metres long and 50 - 70 metres wide strip of landscape northeast of the development boundary behind the Wolfschlugen forest cemetery. This is formed by the Riederwiesen, which absorb water to protect the place from flooding. The wetland should protect people at least during a so-called hundred-year flood and at the same time offer animals and plants a habitat. (ref 3, 11)

The indoor green wall installed at the University of Natural Sciences in Lublin. Apart from its decorative and aesthetical functions, the wall will serve educational and research purposes. The wall consists entirely of moss and does not require watering. It will be monitored regularly to analyse the impact of light conditions for proper growth and development of plants in these type of installations [1,2].

In 2008 the new building of the WGV-Insurance has been opened in Stuttgart. Since then customers and employees of the WGV have enjoyed the beautiful courtyards which contribute to a good working environment. The approx. 3.6 ft. (1.1 m) high, built-in planters have been provided with an automatic irrigation system with the irrigation pipes installed below the elevated concrete slabs. The four courtyards have been planted with a total of 58 small crowned trees. In addition, several extensive green roof areas of approx. 21,600 sq. ft. (2,000 m²) total were installed to improve the Stuttgart climate. (1, 6).

The 40-storey mixed-use skyscraper will serve as an economic catalyst for the French city’s central business district and comprise offices, a hotel, a restaurant, and residences. The tree-covered areas of the tower will give the building its iconic appearance and a portion of that green space will be open to public use (Ref. 1). Trees will line the platform of the building and a ribbon of gardens will curl around the glass facade to its full height (Ref. 2).

Greened-over urban railway tracks (grass tracks) is a city-wide program in Stuttgart which assumes the construction of tram lines with grassed-over tracks. This applies not only to planning and construction but also long-term maintenance (ref 1).

A large urban park in Lublin was built to commemorate John Paul II’s visit to Poland in 1987. The project ensured the utmost possible preservation of the natural terrain so that it forms a harmonious whole with the surrounding landscape. The park serves as a green recreational area for the citizens with its open-air sports facilities and a small amphitheatre for local festivities and extracurricular activities [1].

The garden was designed by landscapers Michèle Orliac and Miquel Battle and realized for a cost of 3 million euros. This "new green lung", as presented by the City Hall of Toulouse, is part of a major urban project that provides for the creation of 500 housing units in the Niel District (Ref. 1). The project involved creating vegetation enmeshed benches (Ref. 7) and using permeable flooring materials that prevent water loss and reduce the potential of flooding (Ref. 8).

The construction of a new main bus station inaugurated in 2014, is part of a desire to reduce greenhouse gas emissions and to encourage users to favor bus routes (Ref. 1). Part of this construction project, a vegetal wall of 210 meters long and 8 meters high has been implemented in order to act on noise (-20 decibels) and visual pollution, and improve air quality. It will be the largest public vegetal wall in France. (Ref. 4, page 26)

The project introduces an urban park in the place of a formerly derelict area and a landfill, located by the river valley of Bystrzyca. The park would increase access to the green recreational area in the city, which is a part of a longer-term plan to make the river’s banks citizen-friendly and easily accessible. The initiative includes: clearing the land and planting greenery, construction of the 'sensory' garden for the youngest users, building walking and cycling paths and infrastructure adjusted to people with disabilities, as well as installation of the nesting boxes, feeders and insect hotels [1].

In 2008, a green wall of more than 500 m^2 using a hydroponic watering system was developed on the side of the Max Juvenal bridge. Designed by Patrick Blanc, french botanist and pioneer in the development of green walls, it is considered an "authentic work of art, which evolves over time and the seasons and contributes to "renaturing" the urban space" (Ref. 4, page 7). The wall is intended to illustrate the benefits that green walls can bring to the environment, such as the reduction of heat islands in urban areas and their contribution to cleaner air due to the production of oxygen and the reduction of CO2 rate by photosynthesis (Ref. 1).
