GLS is committed to equality, to education and to environmental protection.
Certified security and quality
GLS guarantees, checks and improves quality with a pan-European quality management system. It is certified to DIN ISO 9001 and 14001 by DQS, one of the largest international providers of management system certifications. With its quality management system GLS fulfils high, internationally recognised standards.
Highest priority for quality
The comprehensive quality assurance of GLS includes precisely defined work processes, quality guidelines with checking routines, and regular audits. Key quality figures are continuously recorded. In this way GLS always knows precisely how many parcels arrive within the defined standard delivery times.
Seal of approval for environmental management
GLS is an environmentally-conscious company and implements sustainability projects in its national subsidiaries. 18 GLS subsidiaries have obtained the ISO 14001 certification for their environmental management systems. This internationally recognised standard is considered to be one of the most important in relation to environmental management by manufacturers and service providers.
GDP certified transport of medicinal products
GLS also obtained GDP (Good Distribution Practice) certification in Denmark, France, Germany and Ireland. The GDP guideline is binding throughout the EU for pharmaceutical wholesaling. In these four countries GLS meets the stringent safety and hygiene requirements for the non-temperature-controlled transport of medicinal products for human use.
