- Carbon Tracker finds an average 33% discrepancy between reported and real‑world emissions across 17 OEMs covering 80% of global passenger vehicle sales.
- Toyota’s hybrid emissions exceed the total emissions of entire manufacturing groups such as BMW, raising stranded‑asset risk as markets ban internal‑combustion components.
- Ben Scott notes passenger vehicles generate 27% of global oil demand, and each ICE or hybrid sold locks in 10‑20 years of additional oil consumption.
- Ken Maeda warns that Toyota’s hybrid‑heavy strategy heightens long‑term financial risk for the Japanese automotive industry amid accelerating global electrification.
- Michael Wells attributes the “Carbon Gap” to unrealistic mileage assumptions, optimistic PHEV usage estimates, and exclusion of upstream fuel‑production emissions.
Why it matters: Institutional investors risk hidden carbon exposure in legacy auto stocks, while green‑focused funds stand to gain by shifting capital away from Japan’s OEMs that face stranded‑asset threats as electrification accelerates.
