Seltor has a strong environmental focus at all levels and in all its construction projects, and has several projects that are BREEAM certified. We work actively with sustainability, circular economy, reuse and recycling in all our projects.

Seltor is committed to reducing both our own and our customers' environmental impact, which means that all our activities should include more sustainable products and solutions.

Seltor has a responsibility to contribute to the development of a sustainable society. We must ensure that what we do is in line with the UN's sustainability goals and that our solutions are positive for present and future generations. Our solutions and the way we work must provide environmental, social and economic benefits for the future, both locally and globally.

Seltor builds for the future. What we build today will benefit future generations. We therefore invest in the environment and environmental expertise. Seltor will facilitate environmentally friendly use and operation for many years to come. Taking care of the environment during work on the construction site and in the physical building is essential for sustainable development.


ISO certification

Seltor has been environmentally certified under the ISO 14001 standard since 2017, and we have built up a high level of environmental expertise over several years.

Seltor has achieved the following ISO certifications:

ISO 9001 : 2015 Quality system

ISO 14001 : 2015 Environmental certification


Our goal is to cut greenhouse gas emissions from our construction activities. We want to reduce our use of resources and eliminate the use of hazardous substances.

In order to efficiently implement projects with sustainable benefits, we have chosen to invest in digitalization. This offers many opportunities for solutions that promote the safety and health of our employees. Digitalization helps us to plan the environmental solutions of the future and streamlines the construction process. This is in line with our sustainable development.

At Seltor, we care about what we do and how we do it. Our buildings are produced in the most responsible way possible. We emphasize resource and energy efficiency, the least possible impact on the climate and environment, respect for human and labor rights, and of course comply with applicable laws and regulations. Seltor is not only a business, but also a social institution that aims to contribute to responsible and ethical value creation. Corporate social responsibility is therefore closely linked to our core business.

We emphasize environmental focus in all our construction projects, but especially in the following areas:

  • Waste treatment and sorting of waste
  • Emissions to air-soil-water
  • Energy-efficient buildings and construction processes
  • Eco-efficient construction site
  • Environmentally sound materials and chemicals
  • Clean Dry Construction procedures


We phase out harmful materials from the construction process and use products that are positive and sustainable for the environment. Seltor works to reduce the risk of environmentally harmful emissions and negative impacts on biodiversity by continuously risk assessing our action plans. This also includes dust and noise impacts.

Our design managers have a high level of expertise and experience in energy-efficient buildings. Good quality is an important environmental measure, as better quality and a longer lifespan improve the environment. Energy consumption during the construction process is measured and monitored, and building materials and chemicals are environmentally sound. We have an ongoing focus on Rent Tørt Bygg (RTB) in the construction process, both for future users and for our employees on construction sites.

Seltor minimizes waste produced and implements effective source separation on all our projects. We aim to sort better than public requirements.

We are often involved in construction processes with high environmental ambitions and are continuously building expertise to meet today's and tomorrow's requirements for energy-efficient and sustainable buildings.

BREEAM certification is increasingly in demand and expertise in the area is of great importance.



On the Kristian Augustsgt.12 project in Oslo, Seltor has renovated the property based on FutureBuilt's set of criteria for circular buildings. The client's ambition for the implementation was based on a focus on greenhouse gas accounting and emissions. Energy and material use form the basis of some of the largest emissions.

The implementation of the project was based on the circular economy in terms of preserving and reusing existing building components and reusing materials from other construction projects.

In order to implement a project based on a circular economy, Seltor has worked systematically with the client in connection with the reuse survey carried out in the early phase and actively participated in the choice of solutions and materials during the implementation period of the project.
