Analysis by SBP


SBP, Sustainable Brand Platform, is a sustainable project that was launched by Idee Brand Platform in late 2020.

SBP is a platform where designer brands and partners can communicate about their sustainability and improve their sustainable approaches.

SBP strives to be the ultimate platform for brands highlighted for environmental, social and economic sustainability mixed with high design content.


The fashion industry has been known for its high pollution for many years. We have an obligation to respond to the pressure of the climate crisis. The industry has the tools, we just need learn how to use them. We want to be a part of the solution!

We have never claimed to be a sustainable brand, but we have taken small steps towards better choices. We are aware of our shortcomings as a brand in the fashion industry and have learned that being part of greenhushing is just as conflicting as greenwashing. We hereby commit to be open and transparent with the choices we make, as well as honest and humble about our committed goals.

We are committed to care!

*Greenhushing is when a company withholds information about their sustainable actions.

*Greenwashing is when a company gives false environmental impression, or provides misleading information about its products, or the perception of the brand.


According to the Global Footprint Network, we consume more than 1,75 times the earth’s natural resources yearly, and by 2030, we will need the resources of two planets for a year’s consumption. This leaves a massive pressure on our planet from the human demand on the ecosystem.

Unfortunately, we are in the industry that leaves the 4th largest pollution on the environment. On a positive note, this means we can do more, and that is what we intend to do. Our Corporate Social Responsibility plan is based on necessity and moral obligations to help our planet and the environmental footprint we leave in this industry.

To help focus and guide us, we have chosen to work with the UN Sustainable Development Goals. – Responsible Consumption and Production, Climate Action, Life on Land and Partnerships for the Goals.

First off, it has been important for us to go back and start from the beginning. Mapping all our groundwork and hereby have traceability within our supply chain. Even though we have close partnerships with all our suppliers and have been working with many of them for a long time, we needed to rebuild our Corporate Social Responsibility plan from a different perspective and start over, draw new cards and build the strategy from the foundation and up again.


A big part of our Corporate Social Responsibility plan is to use better materials. We know this can be a jungle to navigate in, so we have made an easy overview of our current responsible and nature friendly materials.



Seawool is one of the newest methods when it comes to creating sustainable materials. The name derives from its 99% comparability to wool. Seawool possesses many of the same qualities as well, as it too is heat-regulating, self-cleansing and is nice and soft without being scratchy. Seawool is made from recycled plastic bottles and surplus oyster shells – hence the reference to the sea in the name, Seawool.

Every year, a lot of plastic end up in the ocean or at a waste site for incineration, which is bad for the environment. Luckily, many countries have become better at recycling their waste and recycling plastic, where it can be melted and repurposed as yarn.

The same goes for the oyster shells that is being used for Seawool. They’re collected as a surplus from the food industry, where they throw out up to four million tons of oyster shells each year. When making Seawool, they are pulverized and mixed with the material from the reused plastic bottles.

Seawool thus benefits from the mix of fibers. The plastic bottles make it wrinkle-free and quick-drying, whereas the oyster shells make the fabric anti-static, anti-bacterial and self-cleansing.
1 kilo of Seawool reuses approximately 60 plastic bottles.

Recycled polyester

Polyester tends to have a bad reputation due to its manufacturing of plastic and high environmental impact. However, the many benefits of polyester also tend to be
forgotten. It is a very durable fiber, which is both strong and resistant, and can be reused many times if the process is done correctly. This makes the life
cycle for polyester garments much longer and helps lower the need for disposal of the products.

However, we still need to focus on lowering the environmental impact of polyester production. That is why we at Coster Copenhagen have chosen to use recycled polyester. This way we can help prolong the lifecycle of the fibers.

Currently some of our suppliers are certified with:

o  GRS, Global Recycle Standard for Recycled Polyester

o  COC, on Eco Circle Recycled Polyester Fiber

EcoVero Lenzing viscose

EcoVero Lenzing viscose is produced by the Austrian company Lenzing Group. EcoVero Lenzing viscose is a branded fiber with a certified lower environmental impact. It is made from sustainable wood and paper pulp from certified and controlled sources. EcoVero Lenzing viscose carries the EU Ecolabel as EcoVero Lenzing viscose generates up to 50% lower carbon emissions and water impact than generic viscose.


Organic cotton

Organic farming of cotton uses crop rotation and a biological method to control pests and pathogens, instead of using toxic chemicals and GMOs. This helps reduce soil, air and water contamination. Additionally, this help the fertilization of and the biodiversity in the soil, which is good for both human and wildlife health and well-being. Finally, it also reduces the emission of greenhouse gases.

Currently some of our suppliers are certified with:

o  GOTS, Global Organic Textile Standard

o  GRS, Global Recycled Standard for Recycled Cotton

o  OEKO-TEX Certified Cotton

o  OCS100 Standard, Organic 100 Content Standard

Take care of your garment with organic cotton:

By washing at a maximum of 30 degress you will both save energy and your garment will last longer.


Linen comes from the flaxseed and is thus a plant-based fiber. The flaxseed often does not need more than rainwater and needs a lot less chemicals than other fibers, which causes a lower environmental impact.

Currently some of our suppliers are certified with:

o  GOTS, Global Organic Textile Standard

It's a work in progress, so stay tuned! We will be updating this page regularly.

All the best,
