The project focuses on encouraging residents of Rio de Janerio's Arará favela to install green roofs on their homes, primarily to reduce the urban heat island effect but also to harness the broader social, environmental, and economic benefits which green roofs can provide, "...from providing thermal protection and improving air quality to mitigating stormwater runoff pollution and saving costs for both residents and cities" (Refs. 2 & 3). The individual behind the project, Luis Cassiano Silva, further hopes that introduction of green roofs into the favela which help to improve residents’ quality of life and "describes the emotional benefits of incorporating green space into the favela landscape" (Ref. 2).

Delhi Development Authority (DDA) has established a network of Biodiversity Parks in Delhi with unique landscapes that harbour a diversity of plants, animals and microbes living in ecologically sustainable biotic communities and rendering multiple ecological services. Presently there are seven Biodiversity Parks developed by DDA located across the landforms of Delhi. These parks have a mosaic of habitats with rich floristic and faunistic diversity that function as a dynamic ecosystem. They have ecosystem processes such as organic matter decomposition, regeneration of plants, pollination, resting and nesting of birds and colonisation by other animals. The biodiversity parks in Delhi have proved to provide extreme essential services by creating ecological corridors and maintaining the genetic diversity in an urban setup. Furthermore, these parks have shown substantial potential in storing carbon and other pollutants and help in mitigating climate change. [2, 3]

The construction of "the biggest vertical garden in Uruguay" was completed in 2014 (Ref. 1). The vertical garden has an area of 300m2 and contains over 6,000 plants, of which most are endemic, comprising 35 species and 10 different families (Ref. 2). In addition to being aesthetically pleasing, the garden is intended to reduce temperature, produce oxygen and offset greenhouse gas emissions. It is thought to "contribute...to the filtration of approximately 165 tons of gases per year and [be] capable of producing the necessary oxygen for 255 people, in addition to trapping 130 kilos of dust" (Refs. 2 & 3).

The Bluebelt programme in Staten Island was implemented as it "preserves natural drainage corridors including streams, ponds, and wetlands, and enhances them to perform their functions of conveying, storing, and filtering runoff precipitation or stormwater". (Ref. 2). By delivering "stormwater to engineered systems that are designed to mimic natural streams and ponds which...meander or wind back and forth, the water slows down naturally" (Ref. 1). These actions are intended to "help control flooding, pollution and erosion" (Ref. 2), whilst also providing open green areas for both local communities and a "diverse habitat for wildlife" (Ref. 2). Beginning in 1990, the Bluebelt programme has undergone continual expansion, recognising that "as New York City prepares for rising sea levels and heavier rains due to climate change, Bluebelts offer a natural and effective solution for stable and sound stormwater management" (Refs. 2 & 4). The Bluebelt now includes approximately 400 acres of freshwater wetland and riparian stream habitat and 11 miles of stream corridor (Ref. 4).

A rain garden has been implemented at the Fazenda Lagoa do Nado Municipal Park in Belo Horizonte. The rain garden has been created as "a solution that contributes to the runoff of rainwater, allowing the water to be filtered through vegetation and infiltrate into the soil", with this type of solution being recognised as a method which "recharge[s] the water table, increases biodiversity, improves the local microclimate and air quality" (Ref. 1). The rain garden has been created as a demonstration project within the wider INTERACT-Bio project which is led by the global Local Governments for Sustainability network, ICLEI (International Council for Local Environmental Initiatives) (Ref. 1). As summarised by President of the Municipal Parks and Zoobotany Foundation of Belo Horizonte, Sérgio Augusto Domingues, “This is an important experiment that enables solutions based on nature. The idea is that it, like other mechanisms, complements macro-drainage interventions, helping the city to be more resilient to extreme events related to climate change" (Ref. 3).
According to the Municipality of Belo Horizonte, the Multiannual Government Action Plan (PPAG) aims to implement 30 rain gardens in the municipality by 2025, each garden having an area of ​​150 square meters (Ref. 7).

One of the first public institutions to rise to the climate change challenge in the Philippines is the LLDA, which unveiled a two-wing, four-story green building in Quezon City to mark its 48th anniversary in 2014.
Reflecting the critical mandate of the LLDA to protect the country’s largest freshwater lake, the LLDA building features its own water treatment facility, material recovery facility, and a rain collection system that can hold 60,000 gallons of water. In order to be certified by the Building for Ecologically Responsive Design Excellence, several greened areas have been installed in the building: two “pocket gardens” on intermediate levels and a green roof (Bio Roof) which covers an area of 208 m2. The Bio Roof is integrated within the building’s structure. Its vegetative layer protects the waterproofing membrane from climatic extremes, which allows for the reduction in maintenance and the reduction in the size of stormwater handling facilities. [1]

A green wall of 73 square metres was constructed on the building of the Federación de Entidades Empresariales Privadas de Cochabamba (FEPC, the Federation of Private Business Entities of Cochabamba) (Ref. 1). The vertical ecosystem comprises over 3000 plants of 35 species and is considered the first vertical garden to have been created in Bolivia (Ref. 1). The green wall is considered to have 'beautified' the city of Cochabamba, but is also considered to "contribute... effectively to the preservation of the environment" (Ref. 2).

As part of the "Urban Forest Policy", the first Miyawaki urban forest was created in an area of 2,850 square meters in Lahore, Pakistan. The initiative was a result of a public-private partnership between Lahore Development Authority (LDA) and Restore Green. The project was carried out under the PM Khan 10 billion tree plantation drive. Miyawaki is a technique pioneered by Japanese botanist Akira Miyawaki, which helps build dense, native forests. The approach is supposed to ensure that plant growth is 10 times faster and the resulting plantation is 30 times denser than usual. It involves planting dozens of native species in the same area and becomes maintenance-free after the first three years. [1, 2, 3]

Recognising the benefits which urban forests bring to its citizens, Salvador has committed to protecting and restoring the Atlantic Forest, and has developed its own local framework which goes beyond national requirements (Ref. 1). The city has launched several programmes under its 'Salvador, Capital da Mata Atlantica' initiative, which together aim to restore the forest which has "suffered from severe deforestation" (Ref. 1). Included under the umbrella initiative are programmes such as the "'Delivery of trees', recovery of parks and collective planting" (Ref. 4).

The Sustainable Residential Complex project was a measure taken by the city of Dubai, one of the largest city ecological footprints, with a goal to reduce it to the smallest ecological footprint by 2050. For the past two decades, the UAE government has made an effort to lower its own dependency on fossil fuels, shifting toward more environmentally-friendly sources to power its cities. The sustainable residential complex development project is one of the few initiatives taken by the city administration of Dubai under Vision 2021. Located just outside Dubai the area is the first operational net-zero energy residential complex in Dubai. [1, 2]
