OECD Substitution and Alternatives Assessment Toolbox

OECD has pulled together a compilation of resources relevant to chemical substitution and alternatives assessments.  This includes an Alternatives Assessment Tool Selector, a filterable summary of current Alternatives Assessment Frameworks, links to case studies and other resources, and a list of regulations and restrictions from OECD member countries.


IC2 Chemical Hazard Assessment Database

The IC2 has developed the Chemical Hazard Assessment Database to enable users to search for GreenScreen® and Quick Chemical Assessment Tool (QCAT) chemical hazard assessments. These hazard assessments are an important component of an alternatives assessment. The purpose of this tool is to promote awareness of hazard assessments conducted on chemicals of high concern, facilitate transparency and discussion, and reduce duplication of effort.


GreenScreen® for Safer Chemicals

The GreenScreen® for Safer Chemicals is a rigorous, scientific method for assessing the inherent hazards of chemicals.  It is based upon the process developed by EPA’s Design for the Environment Program, now known as Safer Choice. It was developed by the nonprofit group, Clean Production Action.

American Chemical Society Green Chemistry Institute (ACS GCI) Industrial & Business

The ACS GCI has business case studies as well as collaborative forums for pharmaceutical companies, formulators, and chemical manufacturers with tools, including the Process Mass Intensity (PMI) calculator tool and solvent selection guide.


Quick Chemical Assessment Tool (QCAT)

QCAT is a simplified hazard assessment tool that can be used to compare hazards of different chemicals when looking for safer alternatives. Washington Department of Ecology developed the QCAT to help small and medium businesses that are concerned about the alternative assessment process. The QCAT is not intended to replace more thorough assessment methods like the GreenScreen® but it can provide an introduction to the hazard assessment process, or serve as an initial screen before a more thorough assessment is done. Northwest Green Chemistry provides customized QCAT training and webinars. Contact us for more information.


Safer Choice

The U.S. Environmental Protection Agency's Safer Choice program works with industry, environmental groups, and academia to protect people and the environment by identifying safer products and finding safer alternatives to toxic chemicals.
