Major objectives of automotive product development include continuous improvementsin quality, safety, and the reduction of environmental impact throughout vehicle lifecycle. The use of certain substances in vehicle parts may be a risk factor to human health and the environment. An ongoing dialogue and information flow within the global automotive supply chain, including automobile manufacturers, tier suppliers andmaterial suppliers has been established, called the Global Automotive StakeholderGroup (GASG). Early information and dialogue up and down the supply chain will help facilitate compliance with current and future regulations, as well as take into account customer requirements to ensure sustainable products.The product of the GASG dialogue is the Global Automotive Declarable Substance List (GADSL). The GADSL covers declaration of certain information about substancesrelevant to parts and materials supplied by the supply chain to automobilemanufacturers. The GADSL file is the master document that lists individual declarable substances, substance groups (families) and describes how the GADSL should be used. With Steering Committee contact list.
