bluesign and SCTI donate the pioneering Sustainable Chemistry Index (SCI) Methodology to ZDHC

We are pleased to announce our collaboration with bluesign and SCTI in our journey toward a more sustainable textile, leather, and fashion industry! The Sustainable Chemistry Index (SCI) Methodology, developed in 2022 by bluesign and SCTI, is being donated to ZDHC. This collaboration aims to revolutionise chemical management in the textile, leather, and fashion industries by holistically addressing environmental impact. 

The SCI offers a comprehensive tool for

  • assessing chemical sustainability
  • enhancing supply chain transparency
  • responsible sourcing 
  • and resource efficiency

By integrating the SCI into its Chemicals to Zero (CTZ-A) program, ZDHC will make the content freely available, fostering industry-wide collaboration. This new initiative minimises the impact of the textile value chain on people and the environment by empowering manufacturers and brands to make wise decisions for their chemical change initiatives.

Singapore, St. Gallen, Amsterdam – June 19, 2024

The textile industry is taking a great step forward in sustainable practices as bluesign and SCTI donate the pioneering Sustainable Chemistry Index (SCI) Methodology to ZDHC. This collaboration aims to revolutionize chemical management in the textile, leather, and fashion industries while addressing environmental impact in a holistic manner.

The Challenge of Harmful Chemicals in Fashion

For decades, the use of hazardous chemicals in clothing has been a major challenge. Despite industry efforts with numerous overlapping standards and voluntary schemes - the textile, leather, and fashion industries struggle with varying regulations, inconsistent data, and a lack of common action. Inconsistent regulations, lack of transparency, and little coordinated action hinder progress, while consumers do not receive information about the overall environmental impact of these industries.

A Unified Effort for Sustainable Solutions

Leading organizations in the textile sector are elevating the conversation to tackle these issues head-on with converging assessment tools.

SCTI, a group of innovative and pioneering chemical manufacturers, aims to bring positive change to the textile industry and make sustainable chemistry the norm. bluesign, a renowned sustainability solutions provider, has extensive experience in ensuring safe and responsible chemical management, environmental and worker safety as well as resource efficiency in the production of textiles. The ZDHC Foundation, driven by major fashion brands, is on a mission to detox the fashion industry by providing tools and guidelines for sustainable chemical management.


"We have been partnering with all stakeholders involved for some time and recognized that our market has been operating with multiple isolated approaches. Within SCI content, we are converging several approaches, while raising sustainable chemistry to the benefit of our community"
                                                                                                                             -Wolfgang Schumann, Chairman of SCTI and ZDHC board member


“As a contributor in the development of Sustainable Chemistry Index, we are glad to continue the journey we have started in 2022 with this initiative, and look forward to working with our partners to further move sustainability forward in our industry.”
                                                                                                                                                                             -Daniel Rüfenacht, CEO of bluesign


"Our initiative elevates collective action to new heights and enables the textile and fashion industries to make sustainable choices by taking full advantage of what solidarity can do to power change ".
                                                                                                                                                                      -Isabella Tonaco, SCTI Executive Director


“At ZDHC, our mission is to build a dynamic platform that highlights the transformative journey of sustainable chemistry in the fashion industry. By integrating the SCI into our publicly available Chemical Management Framework, we’re showcasing true thought leadership essential for driving positive change.”
                                                                                                                                                   -Frank Michel, ZDHC CEO
The Start of the SustainableChemistry Index (SCI)

In 2022, SCTI and bluesign announced the development of the first comprehensive Sustainable Chemistry Index (SCI) for the textile industry. The pioneering work leverages best available technologies, while transcends existing chemical assessments, and introduces a one-stop-shopping tool for a broader assessment of environmental impact. Such an approach was missing. Now, the SCI introduces a standard common language for convergence and alignment throughout global textiles.

Innovative Parameters for a Sustainable Future

The SCI brings new parameters to assess how chemical products improve resource utilisation in the processes they are used and along the life cycle of a garment. Key building blocks include Supply chain transparency, responsible sourcing, feedstock reducing fossil dependency, product carbon footprint, resource consumption, efficiency in use during textile production, end-use impact, and end-of-life of consumer applications. This transparent framework makes it easier for the industry to evaluate the sustainability impact of chemicals present in a garment and promote circularity.

A Collaborative Donation to Advance the Industry

SCTI and bluesign are donating, to advance and foster industry-wide collaboration, the SCI to ZDHC as the cornerstone of its Chemicals to Zero (CTZ-A) program. CTZ-A represents the highest level of sustainable chemistry within ZDHC.In 2024, the SCI content will undergo ZDHC's stakeholder engagement and consultation processes, aiming to enhance the Roadmap to Zero Program by addressing sustainability and circularity.  ZDHC will make the SCI content freely available to the public, enabling widespread adoption and impact.
