‘Slussen and a new water regulation plan for Lake Mälaren’ is part of the rebuilding of the city district Slussen (The Slussen Project) (Ref. 1). In connection with the rebuilding of Slussen, SMHI (Swedish Meteorological and Hydrological Institute) was in 2007 commissioned by Stockholm City to review and propose a new regulatory strategy for the lake Mälaren (Ref. 2). A new regulation prevents floods, reducing the risk of saltwater entering the lake, benefiting the natural environment around Mälaren. Further effects will also benefit the ecosystem of the lake (Ref. 3).

Pilestredet Park project was one of the largest urban ecology projects in Scandinavia and included redevelopment of a neglected inner-city quarter of Oslo while meeting high standards of sustainable construction. The project included energy efficient buildings with high quality indoor environments, plenty of green areas, as well as an extensive stormwater runoff management system for the whole site. Pilestredet Park also contributed toward the development of more sustainable construction techniques and products, much thanks to the strict requirements from the Environmental follow-up program developed by Statsbygg and Oslo Municipality's (Ref. 1)

Oslo municipality is underway with the large-scale project of opening up rivers that previously were running in underground pipes. Alna Environmental Park is a part of this project and includes major transformation and environmental upgrade of the river Alna. The Environmental Park runs along the river and has transformed grey structures to accessible parks and recreation areas and now acts as an important resource for Oslo's citizens. Central aims of the project are to improve the self-cleaning ability of Alna, while maintaining biodiversity in the region and to inspire future urban development. (Ref. 1, 3)

Hammarby Sjöstad is the first eco-city district in Stockholm. It is a 'town around a lake' where the planning work begun in the 1980s with an opportunity to expand the inner city of Stockholm. It is one of Stockholm's biggest urban development project and it focuses on water, energy and eco-friendly solutions. As a part of the ambition to create an eco-friendly city district, investments in e.g. green spaces, walkways and several large parks have been made. Furthermore, the Hammarby Model is the eco-cycle which describes environmental solutions used for energy, waste and water and sewage. It was established with a focus on 7 key areas: soil remediation, urban form, transportation, green buildings, energy, waste management, and water efficiency. (Ref. 1, 2, 11)
