Automakers are driving toward eliminating emissions in their vehicle fleets, production plants and supplier networks.
Mercedes-Benz said last week that it will more than halve its carbon footprint per passenger vehicle by the next decade compared with 2020 levels.
The luxury marque will source 70 percent of its energy needs for production through renewable energy by 2030 by rolling out solar and wind power projects at its plants and through power purchase agreements.
In an online presentation, Mercedes-Benz CEO Ola Källenius described climate change as "our generation's most important task."
Mercedes' environmental focus will significantly affect the automaker's suppliers globally.
Sustainability will be an "awarding criteria," Källenius said. "If you want to do business with us in the future, you need to have a sustainable business strategy," he said.
Mercedes-Benz Chief Technology Officer Markus Schäfer said suppliers representing 90 percent of the automaker's purchasing volume will supply CO2-neutral parts.
