Collaborations and Memberships

Collaboration is vital to reduce the impact of the fashion industry on the planet and to slow down climate change

OTB adheres to voluntary initiatives to promote and accelerate the necessary transition for a more responsible fashion industry and to fight climate change

Promoting a more responsible business approach

We recognise the importance of multi-sectoral collaboration to develop a more responsible fashion industry. We need to act together to allow the Fashion System to progress and evolve in this direction.

Collaboration in the Fashion Industry

To face the current and future challenges of the fashion industry, a tight collaboration among all the players along the entire value chain and the industry peers is needed, thus promoting innovation and responsible practices.

In this context, we adhere to voluntary initiatives and organisations to promote a sustainable and coherent development path aiming at ensuring the necessary transition to fight climate change.

The Aura Blockchain Consortium is a non-profit association that aims to promote responsible practices in the luxury industry

The OTB Group is a steering member of the Aura Blockchain Consortium together with LVMH, Prada Group and Cartier, and is represented on the Consortium Board by Stefano Rosso, CEO of Marni, Chairman of Maison Margiela and CEO of BVX. The Consortium promotes a global blockchain-based solution open to luxury brands in any sector and region. Its aim is to accelerate the transition to circular business models, provide customers with additional information on products, and improve transparency.

OTB actively participates in developing projects and defining the strategic initiatives of the Aura Blockchain Consortium, encouraging participation of each brand of the Group. In 2024, OTB registered more than 1 million products of Marni, Maison Margiela and Jil Sander on the blockchain platform in a secure, time-immutable and incorruptible manner, doubling the number of products registered in 2023, for an overall total of approximately 1.8 million products registered since 2022.

The Leather Working Group (LWG) is a non-profit organisation that has identified the internationally recognised reference standard for the leather manufacturing industry

The Leather Working Group (LWG) is a global non-profit organisation that gathers together several stakeholders with the common goal of creating a more responsible industry through the development of leather responsible sourcing practices. Led by a global community of more than 2,200 members who represent the entire leather supply chain, the organisation aims at promoting the change, spreading best practices, and revolutionizing the leather-manufacturing sector. LWG covers one quarter of worldwide finished leather production, with certified factories in more than 60 countries.

Innovative recycling solutions with the Re.Crea Consortium

In August 2022, the Re.Crea Consortium was established by the OTB Group together with Dolce&Gabbana, Max Mara Fashion Group, Moncler Group, Prada Group, Ermenegildo Zegna Group and the coordination of the Italian National Chamber of Fashion (CNMI), in response to the European Directive on “Extended Producer Responsibility for Textile Waste (EPR)” and to related national legislation. The Re.Crea Consortium is active in the management of end-of-life textile and fashion products and the promotion of the research and development of innovative recycling solutions. Currently chaired by Carlo Capasa, President of the Italian National Chamber of Fashion, and with the Vice-presidency of the OTB Group, the Consortium is open to new memberships from key players in the fashion and Made in Italy segment, in order to further strengthen its impact.

The Fashion Pact is a global coalition of fashion companies working together to reduce the industry’s environmental impact

Established in 2019 to reduce the industry's environmental impact, The Fashion Pact is a global coalition that connects leading fashion and textile companies, including suppliers, manufacturers, distributors and marketplaces. The companies involved, including Diesel from 2020 and the entire OTB Group from 2022, collaborate to share best practices and jointly identify innovative solutions to meet common goals, among them: mitigating global warming, restoring biodiversity and protecting oceans and ecosystems.

ZDHC Foundation's Roadmap to Zero Programme

In 2021, the OTB Group and its brands joined the Zero Discharge of Hazardous
Chemicals Foundation, an initiative promoted by the ZDHC organisation to reduce and eliminate the use of hazardous chemicals in the textile, clothing and footwear industry.

In this context, OTB is committed to phasing out hazardous chemicals from the entire products life cycle to protect the environment, factory workers and end consumers, in line with international regulations and the Group's environmental guidelines.

Since 2022, OTB has adopted a Restricted Substances List (RSL) & Product Safety Requirements (PSR) to regulate the management of chemicals for all the Group’s companies. The document, which is revised annually, supplements the regulatory restrictions for global markets on chemicals used in manufacturing with more stringent requirements and standards, such as the latest guidelines of the ZDHC Manufacturing RSL.

Science Based Targets Initiative

The global “Science Based Targets initiative” (SBTi) was created to address climate change issues and, specifically, to help companies achieve decarbonisation objectives such as: limiting global warming to +1.5 degrees Celsius above pre-industrial levels, promoting business innovation for process improvement by adopting low-carbon technologies, reducing business risks by setting science-based targets. In 2023, OTB obtained approval for its ambitious reduction targets and continues to work to achieve them.

Forest Stewardship Council®

The Forest Stewardship Council® is an international non-profit multi-stakeholder organisation established in 1993 to promote responsible management of forests globally through timber certification. In 2024, Diesel again confirmed its commitment to using FSC®-certified paper or cellulose materials for almost all of its B2B and B2C packaging.
