Episode notes
Electrification Demands Full Supply Chain Redesign
- Transitioning to electric fleets requires redesigning many logistics elements like charging, spare parts, and workshops.
- Josué describes electrification as 'not as easy as flipping a light switch' and a major supply chain problem.
Spend-Based Estimates Can Mislead Emissions
- North American firms lean on spend-based and industry averages while Europeans use supplier data more.
- Spend-based methods can perversely inflate emissions when suppliers charge premiums for greener inputs.
Supplier Data Gaps Are The Biggest Barrier
- Lack of supplier data, limited visibility beyond tier-one, and supplier resource constraints top the challenges.
- Single firms cannot efficiently solve these gaps alone without investing heavily in supplier capacity.
