New study: Automakers like Toyota carry climate risks on par with oil majors due to understated emissions

A new report from Carbon Tracker finds that several major automakers, especially Japanese OEMs like Toyota, carry climate-related financial risks comparable to oil and gas producers. The research shows a 33% average gap between reported and real-world emissions from vehicle use, driven by unrealistic mileage assumptions and optimistic plug-in hybrid estimates. When measured as emissions per dollar of enterprise value, some automakers are as carbon-intensive as traditional fossil fuel companies. The report highlights Renault and Stellantis as leaders in emissions transparency, while Toyota faces particular scrutiny ahead of Japan's AGM season. Passenger vehicles account for 27% of global oil demand, meaning every internal combustion or hybrid vehicle sold locks in 10 to 20 years of future oil consumption. Investors may need to reassess portfolio risks as the gap between reported and actual emissions becomes clearer.

This is a solid piece from Carbon Tracker. The 33% gap between reported and real world emissions is the key number here. If investors actually start pricing this in, some automakers are going to look a lot riskier than their current valuations suggest.

The comparison to oil majors is interesting but I want to see the full methodology. tCO2e per dollar of enterprise value is one metric but it depends heavily on how you define scope 3. Automakers have way more moving parts than upstream oil.

Toyota gets called out here and it makes sense. They have bet big on hybrids and hydrogen while everyone else went full BEV. The AGM pressure will be real. But the real test is whether shareholders actually vote with their ballots or just talk.

The PHEV usage estimates are a known weak spot. Most studies show people charge them way less than manufacturers assume. If regulators start requiring real world testing for emissions reporting, that gap will shrink fast.

This feeds into the broader debate about mandatory climate disclosure. If the SEC or EU starts requiring audited scope 3 numbers, automakers will have to fix their reporting. The gap is basically a liability waiting to be recognized.

Renault and Stellantis being leaders on transparency is not what I expected. Would be curious to see how their actual fleet emissions compare on a per vehicle basis. Transparency is good but it does not mean their products are actually cleaner.
