Chemical Management Module

The LWG Chemical Management Module (CMM) is a voluntary additional module, but will ultimately be incorporated as a compulsory new section in the next full update of the LWG Environmental Stewardship Protocol (Version 7.0). The anticipated launch of protocol 7.0 will be no sooner than late 2019.

Following the first year of use, feedback from the auditing team has been reviewed by the Technical Sub-Group along with representatives of the Supplier Sub-Group. Following that review, version 1.2 is now available. This version will remain in place until integration with the LWG Environmental Stewardship Protocol 7.0

The following acronyms are used in the Chemical Management Module:

MRSL	Manufacturing Restricted Substance List
RSL	Restricted Substance List
GHS	Globally Harmonised System
ZDHC	Zero Discharge of Hazardous Chemicals
SDS	Safety Data Sheet
MSDS	Material Safety Data Sheet

The LWG is a non-profit organisation, and our membership is made up of both subscription members and audited members. We are a multi-stakeholder, community-led initiative, and welcome the input and engagement from all of our members to drive us forward. We also collaborate with other key organisations and look to align, draw on each other's strengths, and avoid duplication of efforts where possible.

Subscription members fund all of the work that we do, and includes brands, suppliers, associations and certain traders (who cannot currently be audited). We rely on these subscriptions to do the work that we do.

Audited members include leather manufacturers, traders, sub-contractors, and commissioning manufacturers. The route to membership is through an audit. The LWG is not funded through audits.
