Case Studies and Other Resources

Case studies are descriptions of alternative or chemical hazard assessments that have been conducted by manufacturers, academic institutions, NGOs or government bodies. Case studies are categorized by the type of assessment: chemical hazard assessment and alternatives assessment. An evaluation that includes not only a chemical hazard assessment, but also addresses cost/benefit, exposure, life cycle, materials management, social and/or technical feasibility is classified as an alternatives assessment.

Toolkits are websites that contain a variety of information related to safer chemical substitutions and alternatives assessments.

Organization Toolkit Name Description
ChemHATChemical Hazard and Alternatives ToolboxAn internet portal containing information about hazardous chemicals and safer alternatives, focusing on workplace safety, and includes a searchable chemical hazard database
ANSES (French Agency for Food, Environmental and Occupational Health & Safety) and INRS (French Institute for Research and Security)A Tool to Support the Substitution of CMR SubstancesThis French website was developed by ANSES and INRS. This website focuses on CMR chemicals, and is a database for information about these chemicals and a database for chemical alternatives for CMR. The alternatives database is compiled from industry experience, research and data found in the literature.
French National Institute for Industrial Safety and Environment Protection (INERIS)French National Guidance Service on the Substitution of Bisphenol AThis tool is a repository of case studies and of potential alternatives for Bisphenol-based resins and plastics. It was originally intended for helping companies in France to find alternatives to BPA in food contact material and is now widening its scope to other sectors for BPA and other Bisphenols.

Product rating systems help consumers and purchasers evaluate the relative safety of different substances.

Organization System Name Description
U.S. EPA's Design for the Environment (DfE) BranchSafer Choice Program The U.S. EPA’s Safer Choice Program helps businesses, consumers, and institutional buyers identify cleaning and other products that have met stringent criteria for health and environmental safety. The Safer Choice label on a product means that the EPA scientific review team has screened each ingredient for potential human health and environmental effects and that — based on the best currently available information, EPA predictive models, and expert judgment — the product contains only those ingredients that pose the least concern among chemicals in their class. A list of chemicals that have met the Safer Choice standard is available on EPA’s Safer Chemical Ingredient List (SCIL).
Healthy Buildings NetworkPharos ProjectThis data source is for building materials evaluations and is divided into three parts: building materials library, chemical/materials library and certification information. The building materials library contains products that are scored in 5 categories (see Hazard Endpoints) separately (no aggregate score). The chemical and materials library rates each entry on individual health and environmental impacts of throughout their lifecycle (if applicable) – no aggregate score. Also, not every entry contains comprehensive data. Pharos also contains a database of second and third party certifications and identifies building products that have been certified; certification is one criterion in the scoring system.
GreenBlue®CleanGredients®CleanGredients® was developed by GreenBlue® to help cleaning product formulators identify environmentally friendly ingredients and allow manufacturers to showcase their ingredients. CleanGredients® is a subscription-based online database with 12 cleaning product ingredient categories: chelating agents, colorants, defoamers, enzymes, fragrances, oxidants, polymers, preservatives and antioxidants, processing aids, solvents, starter formulations, and surfactants. Non-subscribers have partial access to website information. Ingredient formulation and attribute claims are verified by an approved third-party.
Cradle to Cradle Certified Products RegistryCradle to Cradle Products Innovation InstituteThis tool is a database of products that have been certified as “sustainable” being evaluated against 5 categories. An aggregated score is calculated. The products are ranked using five ranking categories: platinum, gold, silver, bronze and basic for each categorical score. Each of the 5 impact categories are ranked and an overall ranking is calculated.
