Vienna, Austria

THEWOSAN is Vienna´s programme and funding scheme for thermal and energy renovation of existing residential buildings. Through both thermal insulation of buildings and additional measures for their heating systems, a significant reduction of the energy consumption in residential buildings can be achieved. This has the benefits of a reduction of CO2 as well as air pollutant emissions with linked improvement of the global and local environment.

Zagreb, Croatia

The project 'Urban Gardens' was established in 2013 by the City of Zagreb to enable citizens to temporarily use small cultivable plots in the city for the production of food, spices and flowers for their own needs. Besides the sustainable use of the land owned by the city, the project has many positive impacts like improved availability of healthy food, protection of city nature and biodiversity, promotion of healthy lifestyle and creating new relationships between citizens.

Vitoria-Gasteiz, Spain

The Green Belt is a group of semi-natural periurban spaces partially recovered from degraded areas, such as gravel pits, burnt ground and drained wetlands from the fringe areas of Vitoria-Gasteiz. Through the Green Belt project, the city has been making progress since the 1990s in land management to recover biodiversity by restoring many of its damaged ecological and landscape areas. 

Taipei, Taiwan

Municipal solid waste management remains a challenge for highly urbanized societies. Due to a dense population and limited spaces for waste disposal, Taipei City's local government has implemented several policies for waste management since the 1980s.  One remarkable policy is a waste charging system named “Per-Bag Trash Collection Fee Program”, introduced in 2000, whereby residents are required to purchase specially designated garbage bags for waste disposal. Since its introduction, waste production has reduced by one-third and the collection of recyclable materials increased significantly. 

Lima, Peru

In response to given water scarcity and underdeveloped wastewater treatment, Lima had collaborated with stakeholders to impact national legislation on wastewater reuse and to establish a demonstration project: using treated wastewater for a multifunctional city Eco-Park. This legislation allowing for wastewater reuse for irrigation of urban green spaces has opened the way for further applications with multiple benefits.

Rotterdam, Netherlands

In order to approach climate change as an opportunity rather than a threat, the City of Rotterdam launched the Climate Proof program in 2008. As a city, situated in a low-lying delta, with Europe's largest international port, Rotterdam has developed sustainable water management systems to fight climate change consequences -rising sea level, increases in cloud bursts, extremes in river water levels, longer periods of drought and higher temperatures.

Shanghai, China

Suzhou Creek, flowing through Shanghai, has fallen victim to rapid urbanization and industrialization, carrying most of the city’s waste water. In 1996, the ‘Economic and Social Development Plan for Shanghai’ was adopted which kicked off the 12-year-long Suzhou Creek Rehabilitation Project. Since then, water quality has been substantially improved through the implementation of a combination of measures such as flushing, environmental dredging, re-aeration and interception of wastewater, elimination of wastewater disposal, wastewater treatment, the relocation of solid waste processing wharves and embankment reconstruction.

Bordon & Whitehill, UK

The regeneration of Whitehill & Bordon is meant to transform the area into a low carbon, green and sustainable city. The town is expected to grow from 6,000 homes to over 9,000 when fully built, and new jobs and a new city centre will be created. Inclusion processes have been used to develop a master plan for the area, including projects for renewable and efficient energy supply, transport solutions, nature conservation and new business and work opportunities.

Zagreb, Croatia

The project “Zagreb for Me” aims to start a revitalization of public spaces through the realization of 17 urban interventions in the whole city area of Zagreb at the same time. This distributed approach will improve the general “image of the city” and raise the quality of urban life in segments of housing, recreation, leisure and social cohesion.
