Sihlcity, one of Switzerland's largest shopping malls, is located in the Wiedikon district of Zurich. It was built on the grounds of a former paper mill, Papierfabrik Sihl, near the Sihl River. The Green Wall of the Sihlcity car park is a striking feature of the development at a height of 23 meters and a width of 25.5 meters. The wall is an elegant aesthetic solution to the car park facade, keeps the car park cool during summer, provides insulation in the winter, sound insulation for the busy car park, and an effective deterrent to graffiti.

The "Oasis for Children" project, implemented in Zagreb, is based on the experience of implementing non-institutional education in 5 primary schools in Zagreb. The main objective of the project is to promote the principles of healthy lifestyles, environmental protection, sustainable development and volunteering among pupils of partner primary schools. Throughout the year, students will be educated outdoors in school gardens, on environmental protection, sustainable development, healthy lifestyles and volunteerism. Students will also work on the garden for the opportunity of practising the knowledge gained from the regular education system. Every academic year, new primary schools are added to the project with the increased popularity of the school gardens [Ref 1]

The John Muir Pollinator Way is an initiative by the NGO Buglife to create and restore pollinator habitats along a 215 km long-distance active travel route – The John Muir Way – across the densely populated central belt of Scotland. The John Muir Pollinator Way is the first B-Line ‘pathway’ in Scotland and stretches from Helensburgh in the west to Dunbar in the east (Emilie). It is an ambitious project given the length (215 km) of this pathway. It connects nine different local authorities and 40 km of the total length falls within the Edinburgh local authority area (Burgess, 2016). This not only serves to halt the process of declining pollinator numbers providing crucial ecosystem services, but also helps people to connect with nature. Between July 2015 and March 2017, project partners and volunteers have transformed 19 sites into species-rich grassland. [ref 1]

Revitalization of a large urban park in the Walle and Gröpelingen districts of Bremen. The current park constitutes a neglected area of the former port and shipyards sites with around 4,000 small garden parcels.The local government consulted with numerous societal actors the envisioned project, which aims at the revitalization of the park's both green and blue infrastructure. The goal of the intervention is to create a large recreational park for the districts of Walle and Gröpelingen, which will improve the image of the districts, help with their economic revitalization and provide sustainable practices for urban green care and community gardening (Ref. 2, 3). "Between September 2017 and September 2020, the Green West of Bremen was the focus of the federally funded project "Green Urban Labs" (Ref. 5). As of 2020, "Several of these building blocks have already been started or implemented and have led to an improvement in the cooperation between the actors on site, to an upgrading of the infrastructure and biotopes as well as to an increase in the popularity of the previously rather unknown area" (Ref. 5).

A local government-led project of the renaturalization of the part of the Weser river shore. The initiative aimed to restore part of the river bank to its natural state and to create habitats for the typical local flora and fauna. Additionally, a sand beach for the public was created. The project aimed to increase biodiversity, increase the river shore protection and water management, as well as to improve public access to the recreational area at the water and the attractiveness of the river landscape (Ref. 1, 2, 5).

A private investment project that aimed to create a new building complex in the Findorff district of Bremen and build two large residential buildings "Münchner Bogen" and "Findorffer Tor" with green roofs on top. The green roofing of the buildings was influenced by the local actors - the alliance "Green Bremen" and the advisory board of the Findorff Council. The initiative aimed to contribute to sustainable urban development by the positive impact on biodiversity, rainwater retention, improved local air quality and provision of natural thermoregulation for the buildings (Ref. 1, 2, 3).

A project of the local government developed with EU and federal funds that aimed at the development of the green and beach area in the course of the refurbishment of the flood protection system. The initiative sought to provide a model project for urban flood protection, which can showcase that flood protection measures do not require a separation between city and water and new recreational spaces at the water and shore can be created instead. The project involves redevelopment of the shore area, enlargement of the public space at the shore with additional sand deposit and greenery planting (Ref. 1, 2). The bank area with a beach and recreational facilities opened in May 2019 (Ref. 5).

The project aimed to create a garden on the roof in the Bremen Volkshochschule, developed with the help of local NGO, Gemüsewerft Bremen and local citizens. The initiative involves vegetables and herbs growing, educational workshops on nutrition and urban gardening as well as various social activities. It aims at increasing access to the urban gardening space and increase in ecological awareness of the residents of Bremen (Ref. 1, 3).

A city-wide initiative for the protection of bees developed by the BUND Bremen together with a number of local NGOs, local government and the citizens of Bremen. The project involved the planting of trees and wildflowers that will serve as a food for pollinators in different parts of the city as well as the provision of additional nesting places for the bees. It aims to protect the endangered bee species, increase biodiversity and beautify the city with the new plantings (Ref. 2, 3).

The two-year project "Integrationsgärten" aimed at the creation of three social integration gardens for refugees at different residential districts: transitional house Arbergen 2 (2016), a transitional house at Tannenbergstraße (2016/2017), and in Huckelriede (2017). The project involved various gardening activities and cultural events that aimed at increasing social integration of the refugees, improving their language skills, as well as stimulating neighborhoods to social engagement and participation in environmental issues in the neighborhood (Ref. 2, 3).
