The company will also work towards covering 70% of the energy it needs for production with renewable energy by 2030, up from 45-50% at present, it said.
Around 15% of this energy should come from solar and wind plants on or linked to Mercedes-Benz' own sites, production chief Joerg Burzer said in a presentation.
The rest will be sourced through so-called Power Purchase Agreements (PPAs), where power producers are paid to generate a certain amount of energy over a number of years at a set price.
The carmaker is in advanced discussions to buy additional wind energy through PPAs worth €1billion (RM4.6bil) by 2025, Burzer added.
For now, Mercedes-Benz still relies on gas as a back-up supply source.
"We obviously still need the gas," Burzer said. "We are working on minimising that."
