Future Vision

By early 2022, over 90% of our fabrics were made from certified materials and all manufacturing agents we work with are GRS-certified by 2022. Nevertheless, by 2022 we had an independent sustainability scan conducted by RethinkRebels, who investigated potential social and environmental risks throughout our supply chain. Our main focus over the past 5 years has been to develop a sustainable and quality collection with all the necessary material certifications. All our decisions have always been made as consciously as possible. Analyzing the sustainable business scan conducted by RethinkRebels, we came to the conclusion that a large part of our focus in 2023 should be on documenting our social and environmental requirements. We will do this by setting the following goals;

Goals 2023/2024

- MAIUM GRS certification as a brand.

- Develop a Code of Conduct (COC) to which all our suppliers are committed and signed by all tier 1 and 2 partners by the end of 2023.

- Develop a Restricted Substances List (RSL) and Manufacturer Restricted Substances List (MRSL) to which all our suppliers are committed for all future productions.

GRS Certification

GRS certification is usually limited to the production process. MAIUM goes one step further and seeks certification as a brand. The Global Recycled Standard is an international, voluntary, full product standard that sets requirements for third-party certification of recycled materials, chain of custody, social and environmental practices and chemical restrictions. The goal of the GRS is to increase the use of recycled materials in products and to reduce and eliminate the damage caused by manufacturing (source: Global Recycled Standard Implementation Manual 4.2). 90% of our fabrics are currently certified and traceable through the GRS certification process. Our goal is to also become certified as a brand, this way we can make sustainable and recycled claims on all of our products.

Code of Conduct

In 2023, we are developing a Code of Conduct (COC) for all our suppliers, both those who assemble products and producers of fabrics, trims and even raw materials. This Code of Conduct is based on the BSCI principles because we want to use the BSCI audits as a means to ensure compliance with the COC. In this, we mainly monitor compliance with rules regarding working conditions, working environment and environment & society. All our suppliers sign the agreement to comply with our COC by the end of 2023.


A Restricted Substances List (RSL) contains a list of chemicals and substances that must be kept out of our clothing and manufacturing process at all times. The overall goal of developing an RSL is to reduce the use of hazardous substances in our goods and supply chains. By the end of 2023, all of our Tier 1 and Tier 2 partners should have signed an agreement to comply with the RSL. Through our material certifications, we already know that no chemicals are used in our fabrics that are not allowed. However, we want to have this well documented for transparent communication with our customers and partners.


In line with the EU Green Deal, our industry's circular textiles plan aims to produce every garment 50% from sustainable materials by 2030 and fully circular by 2050. As a brand, we are constantly trying to incorporate circular and sustainable practices into our design process. We are currently exploring what opportunities we see for our garments and fabrics once they reach the end of their useful life. Recycling rainwear is currently a challenge within our industry, so we are exploring options for repair, rental or a second life.

Long-term goals and strategy for 2025

- B Corp certification
- 100% traceability in our supply chain from tier 1 to tier 4
- 100% independent third-party social audits from tier 1 to tier 4

B Corp certification

B Corp certification is an international certification for profit-driven companies that impact people and the environment and have made sustainability an integral part of their operations and are able to create value in alternative ways. To become B Corp certified, their movement does not focus on a single domain, but looks holistically at the entire company. It is about awareness of profitability through a healthy balance between sustainable production and work culture. We therefore consider this an important goal for 2025 and will put it on our agenda as a KPI from 2024.

100% Traceability

To make substantial strides in improving our supply chain, it is imperative that we make our entire supply chain as transparent as possible. Currently, Maium has visibility of its partners from tier 0 to tier 2 and we want to expand this to tier 4 by 2025. By making this fully transparent, we can take responsibility as a company and minimize potential social and environmental risks.

100% Social audits

By carrying out social audits throughout the supply chain (tier 1 to tier 4), in collaboration with our partners, we can detect and improve social risks in our chain. These social audits are now conducted up to tier 2, in 2025 we want to expand this to tier 4.
