Stockholm Royal Seaport will be a fossil-free district with low resource use and minimal environmental and climate impact. The results are reported under the above four areas.
Achievements for 3. Resource Efficiency and Reduced Climate Impact
3.1 Reduce amounts of waste
To date, 212,800 m² of land has been remediated, equivalent to 29% of the area.
874,500 tonnes of excavated materials have been recycled in Stockholm Royal Seaport, which means that approximately 56,000 round-trip journeys have been avoided.
437,400 m³ drainage-pump water has been remediated.
Residual waste in Stockholm Royal Seaport is 104 kg per person/year. According to the resident survey, four out of five households always sort their waste, with the exception of textiles and furniture where the proportion is half. (2019)
Pop-up Reuse has so far been visited by 20,700 people, 12,300 items were given new owners and 6.2 tonnes have been recycled.
The amount of construction waste in new construction varies greatly between the developers; from 25 to 158 kg/m2 GFA.
Distribution of construction waste public open space: 64% material recycling, 34% energy recycling, 2% mixed and 0% to landfill. Some reuse of materials and equipment has taken place.
3.2 Resource-efficient water and effluents
100% of households, 67% of businesses with pentry and 84% of businesses with kitchen have waste grinders installed.
3.3 Fossil-fuel free energy and transport system
On average, Norra 2 is 67 kWh/m² which is 22% above Stockholm Royal Seaports requirement, but 26% below the then applicable Swedish building code regulations. On average, Brofästet is 67 kWh/m², 12% above Stockholm Royal Seaports requirements, but 23% below the then applicable Swedish building code regulations.
According to the 2019 residents survey, 33% of households have agreements on eco-labeled energy.
In total, approximately 1,040 MWh of solar energy is generated locally each year.
8% of car parking spaces in public open space have electrical charging (carpooling) and a fast charging station. 14% of car parking spaces on development sites have electrical charging.
There are currently three filling stations for HVO 100 in Stockholm Royal Seaport.
In 2021, the City of Stockholm’s work (fuels for transport and machinery) has reduced emissions by approximately 1,065 tonnes CO2e , partly through increased use of HVO in contractors and partly through local handling and reuse of masses.
In 2021, the share of renewable fuel used for truck transports made by the City of Stockholm’s own contractors in Stockholm Royal Seaport amounted to 0% and 55% for machinery.
3.4 Low climate impact
Average climate impact (public open spaces): Norra 1: 460 kg CO2e /m2 , Västra: 3,130 kg CO2e /m2 , Norra 2: 270 kg. CO2e /m2 .
Climate impact from energy use in Norra 2: Total amount is 1,640 tonnes CO2e equivalent to approx. 248 kg CO2e /person.
3.5 Good indoor climates
82% (23 of 28) of developers meet gold standard for indoor environments.
The 2019 residents survey shows that 93% of the residents feel that the availability of daylight is generally good or very good, 81% believe that the air quality and 58% that the temperature is very or quite good in their home.
3.6 Sustainable selection of building materials
7 out of 8 wood products on public open spaces used are FSC- or PEFC-labeled. Pressure treated timber is not used in the area and all stones have been checked based on ethical requirements.
Proportion of non-approved deviation of total registered deviations:
- developers: 47%.
- public spaces: 77%.
100% of developers and City of Stockholm contractors document materials in digital logbooks.
