Article 23 — Observatory for specific chemicals with the potential to contribute to emerging chemical risks

1. The ECHA shall establish and manage an observatory for specific chemicals or groups of chemicals that the Commission considers as requiring additional scrutiny. The observatory shall include reliable information on properties, safety aspects, uses and market presence of those chemicals. 2. The Commission shall select the chemicals for the purposes of the observatory referred to in paragraph 1on the basis of scientific and technical progress and using the signals of the early warning system referred to in Article 22. The selection shall include potential contributors to new and emerging chemical risks among innovative rationally designed materials with new or enhanced properties or targeted or enhanced structural features at nanoscale. 3. By 2 July 2026 the Commission shall adopt and publish a list of the chemicals selected pursuant to paragraph 2 by means of an implementing act. The Commission shall review the list regularly and adopt any revision thereof by the same means. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29. 4. For the purpose of operating the observatory referred to in paragraph 1, the ECHA shall: (a) make use of relevant chemicals data incorporated in the common data platform and compile, analyse and curate further available data on selected chemicals or classes of chemicals; (b) commission studies and, where relevant, use the data generation mechanism established under Article 24 to address knowledge gaps or significant uncertainties; (c) make compiled data available to the public through the common data platform or other communication and outreach tools, as appropriate, to facilitate the identification of potential further research needs or risk management measures, and to facilitate informed societal discussion and increase public awareness on the properties, use and safety aspects of specific chemicals, and regularly update those data.
