Chemical Hazard Data Commons


Frustrated that finding hazard information about a chemical substance still requires a long and tedious research project? Want more collaboration with your peers to assess the science that informs us of chemical hazards? Seeking ways to make it easier to make safer products? The Chemical Hazard Data Commons is a tool to help you find resources, work collaboratively to understand the hazards associated with chemical substances, and find alternatives which are inherently safer. It is more than just a new way to search for chemical information. It is first and foremost a tool for collaboration, and your participation will be key to its success.


Data Commons Resources

Search Hazards 

Search for a chemical substance or group by Systematic Name, CAS Registry Number, or an extensive library of Synonyms and Trade Names. See at a glance what is known about human and environmental health endpoints from authoritative hazard lists and GreenScreen assessments. Find the structure, other synonyms, INCHI and other identifiers and key physical characteristics.

Additional tabs provide:

  • Hazards: providing a deep dive into what the authoritative hazard lists specifically say about this substance.

  • Discussion forum about the substance and its hazard listings.

  • Additional Resources that directly link you to the substance’s record in PubChem, ChemIDplus, eChemPortal, HSDB, Pharos, and the ECHA Registration Dossiers.

Share Studies

Multiply your collection of scientific reports by combining your reference collection with others in the Science Registry. Share what you’ve found and gain from others’ work. Then search across our pooled resources. We are using Zotero as our reference engine but can accept exports from other major reference systems.


The Data Commons is more than just a nice aggregator of information sources. Key to the vision is the engagement of Commons participants in Discussions to resolve common problems in the assessment of chemical hazard and the search for safer alternatives. From the Hazard Portal record for any chemical record you can start a discussion or join an ongoing one about issues related to that chemical. The Data Commons also seeks to support cross-cutting discussions about the issues we face in screening, assessment and the search for alternatives. We currently have two such cross-cutting forum underway: one of Chemical Group Population and another on Occupational/Dust hazards. Later this year you will be able to start your own Discussions.

Find Assessments

Browse and search for GreenScreen assessments in the Assessment Exchange. This comprehensive listing gives you access through Pharos to assessments that are in the public domain, as well as to links to buy those that are available for licensed use only.

From Vision to Reality

In 2014, with support from the Forsythia FoundationHealthy Building Network published a white paper and a series of working studies that outlined an expansive vision of the Data Commons. Now with further funding from Forsythia, The Lisa & Douglas Goldman Fund, and The John Merck Fund we are rolling out the first applications of the Commons vision. Learn more about the Data Commons and join the community in making a powerful tool for chemical hazard and alternatives assessment.
