Decarbonising manufacturing processes
How does embodied carbon impact the automotive supply chain ?
CO2 is emitted during material extraction and production, and in the manufacture of parts and vehicle assembly. Vehicle manufacturers have control over CO2 emissions from part manufacture and assembly, but much of a vehicle's embodied carbon of a vehicle is inherited in the materials they purchased.
Carbon emissions are often described in terms of scopes:
- Scope 1 - covers direct emissions from the organisation’s own production processes
- Scope 2 - indirect emissions from purchased energy e.g. electricity
- Scope 3 - indirect emissions (not included in Scope 2) associated with the value chain. e.g. purchased materials
Within the automotive value chain, Tiers and OEMs are understandably interested in what is being done to reduce scope 3 emissions during the manufacture of the materials they purchase.
