Carbon Tracker report: automakers under-report emissions, rival oil firms in carbon intensity

A new analysis from Carbon Tracker finds that many major automakers significantly under-report the real-world emissions from vehicles they sell. The report estimates a median gap of 33% between disclosed and actual emissions, driven by assumptions about vehicle lifetime mileage, hybrid usage, and fuel production emissions. Some automakers, including Mazda and Mitsubishi, show carbon intensity levels comparable to or higher than traditional oil and gas companies when measured against enterprise value. The report warns that hybrid-heavy transition strategies may extend future oil demand and increase exposure to stranded assets. General Motors is flagged for the largest overall emissions gap due to its truck and SUV lineup. Carbon Tracker recommends investors and regulators push for greater transparency in emissions reporting and prioritize battery electric vehicle sales when assessing transition risk.

Carbon Tracker keeps putting out solid work. The 33% median gap between disclosed and real world emissions is a big deal for anyone looking at portfolio risk. Mazda and Mitsubishi being the worst per dollar invested is not surprising given their slow EV rollout.

Yeah, the stranded asset angle is the key part here. If you are financing a new ICE platform in 2026, you are betting on 15 years of fuel sales that might not materialize. The report basically says hybrids are not a bridge, they are an anchor.

The methodology matters here. If the gap comes from assuming lower annual mileage than real world driving, that is an easy fix. But if it is about excluding upstream fuel production emissions, that is a harder accounting question. Would like to see how they handled PHEV usage assumptions.

Regulators should be all over this. If investors cannot trust Scope 3 Category 11 numbers, then capital allocation gets distorted. The SEC climate rule and EU CSRD both require this kind of disclosure. Expect more pressure on automakers to align reporting with real world data.

Interesting that GM gets called out for the biggest absolute gap due to truck and SUV sales. That is a lot of embedded emissions that will take years to unwind. The report is right that every ICE sale today locks in a decade plus of fuel use.
