Goal 12

Responsible Consumption and Production

As a fashion brand, we must take responsibility for the climate crisis. Read more about what we do in the production process and what you can do as a consumer to minimize the impact on the climate.


We incorporate sustainability already at the start of the design process. In 2020, we launched our new basics-line, CC Heart. Our customers have known of and worn our products for many years - that is why we felt that it was time to give our core products a new look and identity. CC Heart thus became the start of our digital design process. With our first 3D designs, we can reduce the number of samples from our production flow and reduce our environmental impact.

As a customer, it is a good idea to have basics in your wardrobe, made in good quality and long-lasting materials, so that you can use them all year round and that they last for a long time. Do not buy new clothes constantly and stick with your basics wardrobe and a few seasonal items. Thus, you can reduce the environmental impact on yourself and the fashion industry.

Hangtags, Labels, Packiaging and Shipping

At Coster Copenhagen, we try to do everything to do our best – even the smallest details can make a big difference!

We produce our hangtags in FSC-certified paper and our care labels in OEKO-TEX certified cotton. 

When you buy your clothes from Coster Copenhagen, we not only do our best to make sure to make our clothes in sustainably resourced materials. We also do our best to ensure sending you our items in a way that has the lowest possible impact on the environment.

We ship our clothes from the production sites to our warehouse via train, instead of on ships or planes, as trains have a lower environmental impact.

Most of our packaging comes from recycled materials. We wrap your items in recycled silk paper and include a postcard made from recycled cardboard. After this, we pack your items in a bag made from recycled and biodegradable plastic, with stickers made from recycled materials. Even the cardboard boxes that we use at our warehouse to store the items are made from recycled cardboard and gets used several times.


When clothes are designed and produced, one of the most important choices is the choice of materials. In the fashion industry, we can do a lot to choose sustainably resourced materials. Here you can read about what materials to look for when shopping for a more sustainable choice.


In the fashion industry, we often end up with what we call “deadstock.” Deadstock is leftover fabric unfit for production. The amount of deadstock is alarming, which is a problem we have taken up with our suppliers. We are working with our suppliers to find solutions for using deadstock and thus reducing the environmental impact.

In the initial stage of redesigning our deadstock, we faced many obstacles. We needed this product to have a minimal impact on carbon emission, and we wanted to be able to use as much of the deadstock as possible. Finally, we ended up on the idea of a square scarf. This way, we can use the entire roll of fabric due to the square-aligned sides. Since not all fabric rolls have the same width, and we need to use up all our deadstock, we decided that they will be produced in different sizes, depending on the width of the fabric roll.

We launched our first production of deadstock scarfs in April 2021.

Sustainable resourced materials


Seawool is a brand-new type of sustainable material. Seawool consists of a mix of recycled plastic bottles and surplus oyster shells from the food industry.

Seawool has a 99% comparability to wool – it is also heat-regulating, self-cleansing and has a soft feel without being scratchy. Other than that, it is also anti-bacterial and anti-static.

1 kg of Seawool recycles approximately 60 plastic bottles.

Recycled polyester and Cupro

Even though polyester promotes the synthetic manufacturing of plastic and has a high environmental impact, it is a durable fibre that can be recycled and reused multiple times. That is why we have chosen to work with recycled polyester to prolong the life cycle of the fabric and lower the need to produce new material.

Cupro is a bi-product of cotton production and helps lower the environmental impact of cotton production, as more of the cotton plant is being used instead of discarded. However, the construction of cupro requires the use of chemicals. These chemicals are used in a closed circuit and do not harm any ecosystems surrounding the production site.


Lyocell is similar to viscose, both in looks and production. Lyocell consists of tree fibres dissolved in a closed circuit and does not harm surrounding ecosystems. The dissolved tree fibres are spun into yarn and then woven into fabric.

Nature-friendly materials

Organic Cotton and Linen

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

Linen comes from flaxseed and is thus a plant-based fibre. The flaxseed often does not need more than rainwater, and the production of linen needs a lot fewer chemicals than other fibres, which causes a lower environmental impact.

Animal-friendly choices

Down Feathers and Leather

At Coster Copenhagen, we do not use down feathers in our products. We have made this choice as we cannot support the sourcing of down feathers. Down feathers used in clothing often come from ducks or geese, and the animals are most often alive when the feathers are taken from them, which is a painful process for the animals.

The leather we use in our products is from India, and in India, it is illegal to kill animals to produce leather, meaning we use leather from the food industry. It also generates less waste as more of the animal is being used.
