ECHA Takes on New Responsibilities to Strengthen Chemical Safety Across Europe
The European Chemicals Agency (ECHA) has taken on additional responsibilities under the European Union’s One Substance, One Assessment (OSOA) package, marking a significant step towards a more coherent, transparent, and efficient chemical safety system in Europe.
Through closer cooperation with EU agencies and national authorities, ECHA will play a central role in streamlining chemical assessments, improving data integration, and strengthening regulatory collaboration to better protect human health and the environment.
One Substance, One Assessment (OSOA): A New Approach to Chemical Safety
The OSOA package aims to ensure that the same chemical substance is assessed in a consistent and coordinated manner across different pieces of EU legislation. By reducing duplication and fragmentation in assessments, the initiative seeks to:
Improve efficiency and regulatory consistency
Enhance early identification of chemical risks
Make better use of existing scientific data
Support innovation and sustainable chemical management
ECHA’s Executive Director, Dr Sharon McGuinness, highlighted the importance of this initiative:
“The OSOA package represents a significant step towards a more efficient chemical safety system in Europe. By joining forces with our partner agencies and authorities, we will create a system that anticipates risks, brings together existing knowledge, and supports innovation.
Our shared goal is clear: a safer, more sustainable Europe through collaboration and science-based action.”
Building a Common Data Platform on Chemicals
One of the key elements of the OSOA package is the introduction of the Regulation on the common data platform and monitoring and outlook framework for chemicals. Under this regulation, ECHA will be responsible for managing a new EU-wide data platform on chemicals.
The platform will be developed and operated in close cooperation with other EU bodies, including:
European Environment Agency (EEA)
European Food Safety Authority (EFSA)
European Medicines Agency (EMA)
European Agency for Safety and Health at Work (EU-OSHA)
under the governance framework and implementation plan adopted by the European Commission.
Key Features of the Common Data Platform
The platform will integrate information from multiple sources and provide a wide range of services, including:
An information platform for chemical monitoring
A repository of reference values
A database for study notifications
Databases covering standard formats and controlled vocabularies
Information on regulatory processes and legal obligations
Data on chemicals in articles and products
Information on alternatives to substances of concern
Environmental sustainability-related data
By bringing these elements together, the platform will function as a one-stop shop for chemicals data, significantly improving transparency and accessibility for regulators, industry stakeholders, and the public.
New Tasks Assigned to ECHA
Beyond managing the common data platform, ECHA will take on several additional responsibilities under the OSOA framework, including:
Developing a monitoring and outlook framework for chemicals
Supporting early warning systems and risk identification
Generating new scientific data when necessary
Promoting the use of scientific research to strengthen chemical safety decision-making
These tasks further reinforce ECHA’s central role in ensuring coherent and science-based chemical assessments across the EU.
Expanded Regulatory Responsibilities
ECHA will also assume scientific and regulatory tasks previously handled by other bodies. These include:
Preparing restriction proposals and processing exemption requests under the RoHS Directive on hazardous substances in electrical and electronic equipment
Setting and reviewing limit values for persistent organic pollutants in waste under the POPs Regulation
Updating guidance on benefit–risk assessments related to the presence of certain hazardous substances in medical devices under the Medical Devices Regulation
Towards a More Transparent and Efficient EU Chemical Safety System
The expansion of ECHA’s responsibilities under the OSOA package represents a major step forward for chemical safety governance in the European Union. By improving data integration, strengthening cooperation between authorities, and ensuring consistent assessments across legislation, the EU is laying the groundwork for a more predictable, transparent, and science-driven regulatory system.
Ultimately, these developments will contribute to better protection of human health and the environment, while supporting sustainable innovation across Europe’s chemical value chains.
