The Environmental Business Council (EBC) of New England announced that Hilary Robinson, PE, has joined the Leadership Team of the EBC Emerging Contaminants Working Group.

The members of the EBC Emerging Contaminants Working Group Leadership Team help to identify programming for EBC events.  Read more about the position, here.

The European Commission updated the Classification, Labelling and Packaging (CLP) Regulation on March 31, 2023, with the following hazard classes (link):

These new hazard classes for CLP of substances and mixtures were adopted on April 20, 2023. New substances on the market will need to be classified and labeled for these new CLP hazard classes by May 1, 2025, and new mixtures by May 1, 2026. Although the specific criteria for the new classifications have not been finalized, draft guidance with important details on the proposed classification scheme was released last month (link).

Complying with these new CLP hazard classes will require considerable effort and resources. Gradient scientists Dr. Tim Verslycke and Ms. Ari Lewis recently presented at PSX 2023 and PCPC 2023 on the likely impact of the new endocrine disruption classes and described a structured approach for screening ingredient portfolios to identify priorities, data gaps, and plan resources informed by prior project work on this topic. If you missed these talks or are interested in discussing further, please reach out.

To learn more about Gradient’s process for portfolio screening against the new CLP hazard classes or to have Gradient present to your company on this topic, please contact:
