At Thirtyfour, we consider sustainability extremely important. This can be divided into two types. On one hand, we look at our ecological footprint, focusing on resource depletion and emissions. On the other hand, we also emphasize social sustainability. After all, our clothing is made by people, and we ensure they work under the right conditions.

To implement both types of sustainability, Thirtyfour has received various certifications and evaluations through its parent company, Tailor & Stitch B.V. For instance, Thirtyfour has achieved ISO9001 and ISO14001 certifications, along with a silver EcoVadis rating. Additionally, Thirtyfour is recognized as a FairWear Leader!

We are proud to announce that Thirtyfour® is certified for both ISO9001 and ISO14001 through its parent company, Tailor & Stitch.

Thirtyfour® produces sustainable clothing with consideration for people and the planet. Continuous innovation and improvement are also key priorities for us. Over recent years, Thirtyfour® has grown significantly, both as a brand and in terms of its customer base. To sustain this growth without compromising on quality and sustainability, Tailor & Stitch decided to obtain ISO9001 (quality management) and ISO14001 (environmental management) certifications.

These standards provide Tailor & Stitch, and therefore Thirtyfour®, with a solid foundation to monitor processes more effectively, leading to an enhanced focus on quality, sustainability, and reliable delivery.

EcoVadis is a leading platform that helps companies gain insight into their sustainability performance. The system evaluates companies in four key areas that are critical for corporate social responsibility: Environment, Labor & Human Rights, Ethics, and Sustainable Procurement. These areas form the basis of the evaluation, helping companies identify strengths and implement targeted improvements.

In each of these areas, EcoVadis assesses not only how policies are formulated but also the concrete actions taken and their actual impact. This thorough process results in a final score from 0 to 100, which places companies into categories: no medal, bronze, silver, gold, or platinum. In our initial assessment, we received a silver medal, placing us in the top 15% worldwide.

With this silver rating, our customers can trust they are partnering with a company that not only takes sustainability seriously but also actively and effectively implements it. This contributes to a better world and helps you achieve your own sustainability goals.

Together, we work towards a responsible future.

Since its inception, Thirtyfour has been an active member of the Fair Wear Foundation (FWF). This nonprofit organization is dedicated to improving the apparel industry, a mission to which Thirtyfour is committed. As a Fair Wear Member Brand, Thirtyfour adheres to Fair Wear's principles and guidelines:

• Transparency about the production chains and steps Tailor & Stitch takes to improve working conditions.
• Active and long-term cooperation with factories to implement and embed Fair Wear’s improvements and guidelines.
• Monitoring of factories and reporting on progress and challenges in compliance with Fair Wear standards.
• Providing training and support to factories and workers to raise awareness and capacity to meet the standards.
• Developing and implementing concrete improvement plans for factories that do not meet the standards.

Brand Performance Check Over the past year, we have worked hard to professionalize our efforts in this area and embed them into our management systems. Every year, Member Brands are evaluated based on their commitment to and integration of these principles into daily operations through a Brand Performance Check.

This year, our efforts were rewarded with a benchmarking score of 85, giving us Fair Wear Leader status!

This category is for Member Brands that perform exceptionally well and operate at a high level. Leaders demonstrate best practices in complex areas such as living wages and freedom of association.

In addition to our exciting developments in the area of sustainability, we are pleased to share our first Sustainability Annual Report with you! Over the years, sustainability has increasingly played a role within both Thirtyfour® and Tailor & Stitch.

As both a company and brand, we are taking many steps to become more sustainable. However, it would be unfortunate if these sustainability efforts went unnoticed. Therefore, we have prepared a Sustainability Annual Report in which we review the sustainability actions we have undertaken over the past year and look ahead to the future.
