Volvo is exploring cars made using fossil-free steel, ensuring its cars are environmentally friendly right down to the chassis. : Volvo hasn't been shy about wanting greener cars between its electric car plans and efforts to ditch leather, but it's now extending that eco-conscious mindset to the very bodies of those vehicles.

The automaker is exploring how SSAB's hydrogen-based steelmaking process could be used to shrink a car's CO2 footprint and make a stronger case for electrified vehicles.
