Projects funded by the Green Bond Program

Projects we have funded through Green Bond program will be listed here. The projects will be added to this page as soon as they have passed the selection process.

Previously, the city has chosen to fund

  • Lackarebäck water plant and purification filter
  • GoBiGas – April 10, 2018 As a result of Göteborg Energi AB’s decision to discontinue its current operations and operations in GoBiGas, the SEK 920 million invested through green bonds will be reallocated to other green loan-financed Projects.
  • Gatubolaget electric cars.

In 2014,  more green projects have been added to portfolio, in addition to continued investments in existing projects, among others:

  • Gryaab denitrification Project
  • Park & naturförvaltningen tree planting
  • Göteborg Energi Celsius Project
  • Lokalförvaltningen – projects in sustainable housing

In 2017, the sewage pump station Kodammarna was added to the green portfolio.

In 2018, two new projects have been added to the green portfolio:

    • GöteborgsLokaler – project in sustainable housing
    • Göteborg Energi – renewable energy


GöteborgsLokaler – sustainable building

Selma Town hall

Selma Town hall, is a 5,500 square meter, four-story building housing a community service, library and leisure center, in addition to activities for senior citizens, a cultural school, a restaurant and daily activities.

The vision is to be a welcoming and social environment full of life. The mixture of different amenities promotes a creative environment with opportunities for interesting and inspiring meetings between people with different backgrounds. The facades of the house are designed as large curtains where small and larger openings expose the activities inside.

The building is silver-certified by Sweden Green building Council, which means an energy consumption less than or equal to 75% of the Swedish building code and a energy for heating requirement of 40 kWh/sqm or less. Regarding energy sources, there is also a requirement that at least 10% must come from renewable energy (environmental category 1) and less than 25% from non-renewable sources (environmental category 4). In addition to energy requirements, Sweden Green building Council also implements high indoor environmental (noise environment; air quality; daylight; moisture; thermal climate and legionella) and building material (removal of dangerous substances; documentation of building materials) requirements.

Göteborgs Energi – investment in renewable energy

Sweden´s largest solar park ‘Nya Solevi’ has been built by Göteborg Energi at Säve airport. Nya Solevi covers an area of 11 hectares, equal to the size of 16 football fields combined.
The facility comprises 20,000 panels with an expected lifespan of 30 years, which will produce about 5.5 GWh of electricity every year. This is sufficient to power 1,100 private houses.
Göteborg Energi announced a competition to determine the name for the park. The winning contribution, Nya Solevi, has a local connection. The largest two football stadiums in Gothenburg are named ‘Gamla (old) Ullevi’ and ‘Nya (new) Ullevi’. In addition, the name implies renewable solar energy.


Eco-cycle and water administration

Kodammarna- sewage pump station

Sketch of Kodammarna

The purpose of the investment is to secure the operation of Kodammarna pump station and reduce the overflow to the river Göta älv. The pump station drains sewage from 160,000 people, and it is crucial that it is in continuous operation. The pump station will be more energy efficient and measures to adapt the station to higher water levels will be made. The roof is prepared for installation of solar panels. The work is expected to be completed in 2022.


Lokalförvaltningen – projects in sustainable housing

 We build only low-energy when we build new buildings

A new building in Lokalförvaltningen auspices should only use a maximum of 45 kWh / year of energy for heating, hot water and building operations. This is about 60% lower than required in the national building regulations and is in line with passive house standard. In addition, we make very high demands on the energy performance of the components that affect the company’s energy consumption, such as energy saving light with smart control, energy-efficient appliances.

We put very high standards on materials use

We assume that children are more sensitive to exposure to hazardous materials. Therefore, we avoid such endocrine disruptors. Durability over time is a key word. Several projects have green roofs, known as sedum roofs to increase biodiversity, add more green in the urban environment, reduce stormwater flows, creating better microclimate and promote noise reduction.

‘Krumeluren’ is an energy efficient building with passive house standard. In addition, there are no plastic carpets with hormone-altering plasticizers and no material with high emissions. The building also has green roof to add more green in the urban environment, reduce storm water flows, create better microclimate and promote noise reduction.

Göteborg Energi AB – investments in district heating

Celsius – district heating for boats

In Celsius, the city has a “lead” position and Göteborg Energi AB project manages the various European cities participating in the project. Purpose is to show how the district heating and cooling can be used in particular to utilize waste heat in a city and maximize energy efficiency. EU demands this kind of solutions to achieve the 20 percent energy efficiency  by 2020.

A measure implemented by Celsius project is to heat a large ferry with district heating when it is docked. Göteborg Energi’s district heating system supplies the Stena Danica with hot water by a new heat exchanger. Gothenburg and Stena Line are the first in the world with this. Since earlier the ferry is also connected to the land electricity network. This saves emissions of 500 tons of carbon dioxide per year.

Celsius – district heating for domestic appliances

Instead of heating water in a washing machine or air in a dryer with electricity, a use can be made of district heating. Using district heating, it is possible to replace up to 80% of electricity demand and reduce the power requirement of electricity by up to 90%. With disting heating, the heat comes from the heat exchanger to the machines, instead from of electricity.


Gryaab – Denitrification

In order to fulfill Sweden’s commitments under the Baltic Sea Action Plan and to meet future population growths, Gryaab estimates that it is necessary to increase nitrogen retention further. Gryaab has decided to invest SEK 360 million on an expansion of existing denitrification facilities. The new plant if expected to be taken into use in 2016. The nutrient nitrogen is of great importance for the eutrophication of the North Sea.

Gryaab nitrogen removal is done in two steps. In the first step transforms bacteria ammonium into nitrate and in the other nitrate to nitrogen gas. The nitrogen then end up in the air rather than to fatten the sea. The new extension will increase capacity in the first stage.

A reactor with so-called mobile carriers will be built. The carriers are plastic pieces which bacteria adhere and grow into. The use of mobile carriers is an effective way to purify water in a small space. Prior to the decision, consultations with Gryaab seven owner municipalities were conducted. All municipalities were in favor of the investment.


Lackarebäck water treatment and purification filter management cycle and water

  • The largest ultrafilter built in Scandinavia
  • Water treatment by ultrafilter
  • Ultra-Filter is an independent microbiological barrier, which means a good barrier effect even during disturbances
  • Capacity Increase by 40%
  • Ready to use 2015
  • Total cost 700 million

Estimated effects of the project

  • Capacity increase of 40%
  • Socio-economic benefits in terms of lower disease outbreaks that saves up to 290,000 days of lost productivity from 2014 to 2038
  • Socio-economic benefits in terms of cost savings of 1.4 million hospital Days

April 10, 2018 – As a result of Göteborg Energi AB’s decision to discontinue its current operations and operations in GoBiGas, the SEK 920 million invested through green bonds will be reallocated to other green loan-financed projects
  • Large-scale production of biogas
  • Effective – high efficiency in production and recycling of waste heat for district heating and electricity
  • Flexible – can withstand varying quality of raw material
  • Platform for development within industry and academia

Estimated effects of the project

When the plant is in full production, the delivery will amount up to 800-1000 GWh, equivalent to fuel for between 80,000 to 100,000 cars.

Electric cars         street.


Gatubolaget has purchased a number of electric vehicles for city departments and companies. The goal was 100 electric vehicles in the city fleet by 2015.
