Annual highlights

Stockholm Royal Seaport shows the way towards a sustainable future. Here are some highlights from the annual sustainability reports from 2015.

2023

Climate analyses were conducted for the detailed development plans for the Kolkajen and Valparaiso phases. Developers delivered preliminary climate calculations for their buildings.
Developer Obos and the City of Stockholm selected the architectural team from Cobe and Yellon for the "City Lights" development, formerly Gasklocka 4.
A new wet screening facility opened at the Mass Consolidation Centre to increase the local reuse of excavated materials.
IIn 10 years, the amount of plastic packaging and residual waste from households has been halved.
The Construction Consolidation Centre initiated the reuse of construction and installation materials.
The “Grey Turns Blue” R&D project demonstrated significant potential for using treated greywater for irrigation. Three new R&D projects will start during the year.

The Stockholm Transport Museum opened, and Bobergstorget was completed.
Climate-enhanced concrete has been tested on a temporary pile deck for the Lidingö Line. This concrete replaces some of the cement with blast furnace slag, a by-product of steel manufacturing.
For the Kolkajen and Ropsten phases, extensive amounts of contaminated soil needed remediation. Due to new technology that stabilizes the soil while treating it, the soil can be remediated and strengthened on-site. This not only halved the costs but also saved 12,000 truck transports.
The R&D project MACRO (Food in Circular Robust Systems) demonstrate that sorting wastewater systems contribute significantly to environmental gains by enhancing the potential for recovery of heat, water, and nutrients, and also offer opportunities for biogas production.

The purifier building, Reningshuset, in Gasverket wins the ROT Prize for preserving existing values.
Barge transport of excavated materials reduces the number of heavy transports. A new environmental permit allows for the transport of materials by sea to and from the Mass Cosolidation Centre. The City of Stockholm has initiated a collaboration with Stockholm Region to reuse rubble from the metro expansion. The resource reuse saves 50,000 heavy transports.
The City of Stockholm becomes the first municipality in Sweden to use an entirely electric truck for construction transports.
The purity level of the plastic fraction in the vacuum waste collection system was 99% during a spot check.
The stormwater management in Stockholm Royal Seaport has received significant attention.
The revised sustainability program, version 3, adopted by the City Council.

An EU project on energy-positive districts begins, titled Cities 4 Positive Energy Districts.
The library opens on Bobergsgatan.
A digital dialogue on a temporary park, the Pop-up park, 440 people participated with 1,390 suggestions.

Gasverket has opened, featuring the new primary school Bobergsskolan, the sports hall Hjorthagshallen, and the rock-climbing facility Klätterverket.
Occupancy has begun for the two plus-energy buildings in Brofästet.
The oil operations at Loudden have been discontinued; remediation of the land and demolition of the old tanks have started.
Continued support from Vinnova for MACRO, Food in Circular Robust Systems, an innovation project on sorting wastewater systems.

One of Stockholm's largest solar panel installations is located at the newly established Mass Consolidation Centre in Frihamnen.
For the first time, Stockholm Royal Seaport participated in the Open House Stockholm architecture festival.
A spring market at Storängstorget and the unveiling of seven bronze sculptures in Hjorthagsparken.
During the year, the project received 7,000 study visits. In total, over 33,000 people have visited since 2012.

Inauguration of the interactive water art installation at Storängstorget.
Construction begins for the primary school Bobergsskolan in Gasverket.
Final report of the innovation project C/O City, highlighting the importance of urban greenery.
Land allocation competition starts for the Kolkajen phase.
The revised sustainability program, version 2, adopted by the City Council.

Occupancy began in Norra 2 – the first phase fully developed with sustainability requirements.
A new land allocation policy was tested in Värtahamnen. For the first time, the City of Stockholm conducted a land allocation competition at a fixed price, selecting based on architectural quality and sustainability criteria.
12 million in research funding over the year.
300 delegations visited Stockholm Royal Seaport and a new forum, 'Hållplatsen', for sustainability dialogues with preschool children was launched in the district.

A mobile reuse centre was tested in Stockholm Royal Seaport. Innovation dialogues with preschool children were conducted.
Early dialogues were held for public spaces in Kolkajen-Ropsten. Many good suggestions were gathered and have influenced the development of the area's urban park, water arena, and quayside.
Stockholm Royal Seaport was awarded the prize for the best sustainable urban development project at the UN Climate Conference in Paris by C40, Cities Climate Leadership Group.
Stockholm Royal Seaport published its first annual sustainability report.
