The implementation of ECHA’s substitution strategy to safer chemicals requires collaboration between several stakeholders. Collaborative networks play an important role in coordinating and advancing innovation and informed substitution.

Network on substitution

ECHA has set up a network for stakeholders for exchanging information on substitution and promoting cross-border collaboration within the EU. The inaugural meeting was held in October 2017.

Interested in joining the network? It is open to all stakeholders interested in actively supporting substitution initiatives in the EU, bringing together public authorities and agencies, industry, NGOs, academia and consultants.

 Substitution to safer chemicals - European Information Sharing Network

The LinkedIn group is a collaboration space to discuss and share information on substituting to safer chemicals. The group aims to bring together authorities, industry associations, companies, researchers, NGOs and other relevant actors with a demonstrated interest and experience in substitution at EU level.

 Network of REACH SEA and Analysis of Alternatives practitioners

The Network of REACH SEA and Analysis of Alternatives practitioners (NeRSAP) has been set up to promote the exchange of views and information on concepts, methods and experiences related to the socio-economic analysis and analysis of alternatives under REACH and the EU or national chemicals legislation. The network is based on collaboration between ECHA, Member States and stakeholders from industry and NGOs.

OECD/UNEP Global Perfluorinated Chemicals Group

The group facilitates the exchange of information on perfluorinated chemicals (PFCs) and supports a global transition towards safer alternatives. It brings together governments, industry, academia and NGOs from both developed and developing countries, organising webinars and events and publishing regular surveys on the release and use of PFCs.

International Sustainable Chemistry Collaborative Centre

An independent, international institution based in Germany, the centre develops and promotes sustainable chemistry solutions worldwide. Its activities are geared towards moving entire supply chains to sustainable circular economy models, avoiding waste, minimising the use of hazardous chemicals, and making better use of natural resources.

Association for the Advancement of Alternatives Assessment

The Association for the Advancement of Alternatives Assessment (A4) is the only professional association solely dedicated to advancing the science, practice, and policy of alternatives assessment and informed substitution. A4 is an interdisciplinary community of researchers, practitioners, and others working collaboratively to accelerate the transition to the use of safer chemicals, materials, processes, and products.

Green Chemistry & Commerce Council

A multi-stakeholder collaborative, the Green Chemistry & Commerce Council drives the commercial adoption of green chemistry by catalysing and guiding action across all industries, sectors and supply chains.


A collaboration network between NGOs and businesses working together to accelerate the transition to a safer, healthy economy, BizNGO’s mission is to promote the creation and adoption of safer chemicals and sustainable materials, thereby creating market transitions to a healthy economy, healthy environment, and healthy people..
