Dearreaders,
Oneofoursixenvironmentalprotectionandenergyguidelinesreadsasfollows:“Westrivetodevelopproductsthatarehighlyresponsibletotheenvironmentintheirre-spectivemarketsegments.”Toachievethisgoalwehavetoincorporateenvironmentalprotectionintoourproductsfromtheverystartofvehicledesign.

Lifecycle has been present-ing and documenting the Environmental Certificates for Mercedes-Benz vehicles since 2009. If you‘re look-ing for detailed information about the complex matter of vehicles and the environ-ment, you‘ve come to the right place. The brochures are available for download from www.mercedes-benz.com.
As early as 2005 the Mercedes-Benz S-Class was the first-ever vehicle to be awarded the Environmental Certificate from TÜV Süd.
For ten years now, Mercedes-Benz has been compre-hensively analysing and documenting all environmentally relevant aspects of important new vehicles – from manu-facture to recycling.
