The Silent Revolution for a Safer, Competitive Future
A unified digital future for chemical safety that protects health, boosts competitiveness, and builds public trust
In the complex world of chemicals, a quiet revolution is underway in Europe. Imagine a world where every substance—from the dye in your child's toy to the preservative in your food—has a single, transparent safety dossier accessible to all. This is the ambition of Europe's groundbreaking "one substance, one assessment" initiative, a ambitious plan to transform chemical safety for the 21st century.
For decades, information on chemicals has been scattered across different agencies, systems, and formats. This fragmentation slows down safety assessments, creates regulatory uncertainty, and ultimately impacts consumer trust and industrial innovation. Today, Europe is building a unified digital future for chemical safety, creating a system that promises to protect health, boost competitiveness, and build public trust all at once.
Currently, businesses and member state authorities must submit chemical data to a multitude of EU agencies under various pieces of legislation. This has resulted in a patchwork of information, held under different data-sharing conditions and formats. This fragmentation makes it difficult for authorities and the public to get a clear overview of what is known about any single chemical.
The lack of a unified system increases the likelihood of inconsistent safety assessments across different regulations. It also hampers the ability to quickly spot emerging chemical risks. For an industry already facing significant economic headwinds—with gas prices 3.3 times higher than in the US and capacity utilization at a low 74%—this administrative complexity is an additional burden on competitiveness4 .
Data scattered across multiple agencies creates regulatory uncertainty and slows safety assessments.
In response, the European Union has embarked on a major reform known as the "one substance, one assessment" (OSOA) package. In June 2025, the European Parliament and the Council reached a provisional agreement on this key deliverable of the Chemicals Strategy for Sustainability1 .
The OSOA package is composed of three core legislative proposals designed to create a more coherent and efficient framework for chemical management1 :
The main objective is to increase the protection of the environment and human health while also facilitating the functioning of the internal market for chemicals. As stated in the adopted amendments, this improved integration of information will establish a cost-effective digital infrastructure, improving predictability and transparency while reducing the administrative burden and overlaps8 .
At the heart of this reform is the common data platform on chemicals, to be managed by the European Chemicals Agency (ECHA). This platform will be a one-stop-shop for chemicals data in the Union, serving as a single point of reference8 .
It is designed as a digital infrastructure that brings together chemical data and information generated under the wide range of EU chemical laws. Its goal is to create a common knowledge base that enables better, more complete, and more robust scientific assessments. By collecting all existing data on chemicals in the EU, the platform is also expected to foster innovation and support the development of advanced testing methods and models, potentially reducing the need for animal testing8 .
Central digital hub for all chemical data serving as a single access point for information with improved transparency.
Clearer roles and improved collaboration between EU agencies for more coherent and consistent risk assessments.
Technical tasks centralized at ECHA for streamlined processes and reduced duplication.
| Component | Key Function | Expected Benefit |
|---|---|---|
| Common Data Platform | Central digital hub for all chemical data | Single access point for information; improved transparency |
| Agency Cooperation | Clearer roles and improved collaboration between EU agencies | More coherent and consistent risk assessments |
| ECHA Task Re-attribution | Technical tasks centralized at ECHA | Streamlined processes and reduced duplication |
The creation of the common data platform can be viewed as a massive, real-world experiment in data integration and governance. The process is methodical and structured to ensure both utility and reliability.
The platform will bring together chemical data from various EU agencies and legislative sources, making it findable, accessible, interoperable, and reusable8 .
A crucial step involves creating a common data dictionary. This means aligning the definitions of concepts (semantics) used across different reporting frameworks. For example, ensuring that the statistical concept "Type of instrument" and the supervisory concept "Instrument" are mapped to a single, clearly defined term6 .
The technical work is being implemented through a phased legislative approach, with the package going through formal adoption by the Parliament and Council before entering into force 20 days after publication in the Official Journal1 .
The early outcomes of this "experiment" point to a transformative shift in chemical governance. The system is designed to establish a monitoring and outlook framework for the early detection of chemical risks1 . This proactive approach moves the EU from simply managing known risks to anticipating emerging ones.
The platform will also provide a framework of indicators to monitor the drivers and impacts of chemical pollution and measure the effectiveness of chemicals legislation over time8 . This data-driven feedback loop will allow policymakers to refine regulations based on evidence, ensuring they remain fit for purpose.
| Data Source | Example of Data Contributed | Platform Integration Benefit |
|---|---|---|
| EFSA (Food Safety) | Chemical monitoring data on food and feed samples3 | Holistic view of chemical presence from environment to food chain |
| ECHA (Chemicals) | Hazard classifications, REACH registration data | Foundational data for all substance assessments |
| Other EU Agencies | Data from pesticides, medical devices, and biocides regulations1 | Coherent "one substance" assessment across all product types |
Building and operating a system of this scale requires a sophisticated toolkit of regulatory and technical solutions. These are the essential "reagents" making the chemical data revolution possible.
| Tool / Solution | Function | Role in the Chemical Data Platform |
|---|---|---|
| Common Data Dictionary | Harmonizes definitions and terms across reporting frameworks6 | Ensures all stakeholders mean the same thing when referring to a chemical property, enabling reliable data comparison |
| Standardized Formats & Controlled Vocabularies | Provides common structures and terminology for data reporting8 | Makes data from different sources interoperable and machine-readable |
| NACE Revision (Nomenclature of Economic Activities) | Updated statistical classification for economic activities6 | Allows banks and authorities to consistently classify business counterparties, improving risk assessment across the financial chain |
| Machine Learning Techniques | Advanced analytical models for risk prediction (as used in banking internal models)9 | Potential to analyze vast chemical datasets to identify hidden risk patterns and predict emerging hazards |
Ensuring consistent terminology across all chemical data sources for reliable comparisons.
Creating interoperable, machine-readable data structures for seamless integration.
Leveraging AI to identify risk patterns and predict emerging chemical hazards.
The creation of Europe's unified chemical data banks represents a significant step toward a future where chemical safety assessment is not just a regulatory hurdle, but a dynamic, transparent, and efficient process.
"Better and faster protection of people's health and the environment"1
"A more coherent, predictable and transparent assessment of chemicals" used in everything from medical devices to toys, reducing administrative burdens and creating a more level playing field1
As this system evolves, it will not only help manage the chemicals of today but also illuminate the path for the safe and sustainable innovations of tomorrow, proving that good data is indeed the foundation of a healthy and competitive society.
