Stockholm Royal Seaport

Sustainability Report

Research and innovation projects

To reach Stockholm Royal Seaport's ambitious sustainability goals, new knowledge, systems, and processes are needed. Around 40 projects have been completed, with 11 ongoing in construction, mass consolidation, water & wastewater, digitization, electrification, and more.

Climate impact analysis of a detailed development plan

The purpose of a climate impact analysis for an entire detailed development plan is to place various building components and the construction phase in one context and identify the factors driving climate impact. The objective is to develop a tool for early-stage analysis of climate impact during the detailed development planning phase.

Innovative construction logistics

A Construction Consolidation Centre for building materials minimize the number of heavy truck transports made to and from Stockholm Royal Seaport construction sites. Co-ordination of transports by the centre, in addition to waste management, cuts the number of transports by as much as a half.

BEAst: Environmental data follow-up

In order to achieve a climate-neutral and competitive construction sector, one step is to measure and capture environmental data that can be evaluated. Currently, the city is testing the BEAst system to capture all emission data from construction production regarding transportation, building materials, and construction processes.

Eco-cycle model
In progress

Stockholm Royal Seaport's Eco-cycle model

An ambitious effort of requirement setting, monitoring, and data collection has been underway for several years. Parallel to that, the ambition has been to develop an interactive circular economy model called 'Reflow'.

The LocalLife project is an innovative communication platform for people in local communities, for example a city district. Pilot studies were conducted in Hammarby Sjöstad, Stockholm Royal Seaport, Storsudret on the island of Gotland and Ebbepark in Linköping.


The Construction Sector's Environmental Calculation Tool, Climate Calculation Test

The Environmental Administration, the Development Administration, and the housing companies have together tested and evaluated IVL's industry-wide climate calculation tool.

Construction site electrification

The project "View from the Driver's Seat" aims to facilitate the introduction of electric trucks and electrified work machines at construction sites.


Procurement of electric truck

The purpose of the electric truck is to reduce the environmental impact and noise from construction transport, and through the use of swap body systems, increase flexibility to avoid diesel-powered auxiliary machines for unloading. The goal is to minimise the emissions of greenhouse gases from construction transport.

Connected Stockholm Royal Seaport

Connected SRS was initiated with the aim of continuing to explore how IoT and increased data sharing could be used as a tool in sustainability work, this time based on the city’s strategy.

Green structures as active components in the urban environment

C/O City was a research and development project based on the challenges related to climate change and the deterioration of ecosystems due to urbanisation. The project was intended to develop knowledge about how Stockholm Royal Seaport’s green structures could support and develop ecosystems and biodiversity and maintain valuable ecosystem services.

Recycling centre of the future

Innovation procurement for recycling centre of the future

Stockholm Royal Seaport contributes to make it easy to recycle in the area with an innovative platform solution for the collection and disposal of bulky waste with high environmental requirements. The project is the initiative of the Development Administration and Stockholm Vatten och Avfall, both City of Stockholm.

Smarter Greener Cities

As part of the urban development project Stockholm Royal Seaport, work is being done into how smart technology can strengthen the dialogue and feedback between nature and people and help us become better at interpreting nature – especially when nature is under pressure, such as during periods of heavy rain and in dry, hot summers.

A roadmap to a fossil fuel-free city district

The purpose of the project was to develop strategies to ensure that Stockholm Royal Seaport will be fossil fuel-free by 2030 and to contribute to developing and disseminating methods and experiences internationally for how to work towards, monitor, and calculate climate impacts in a city district.
