A comparison
Coffee, one cup and Passenger car tyre
Two figures compared the only honest way: calculated together, so that what they have in common moves them together, and read as how many times larger one is than the other, with a range.

Side by side, per kilogram
Scenario Conservative, using FIGARO 2023. Each figure is the middle result of 2,000 runs of the calculation, with the range that holds nine in ten of them beside it, and the grade that range earns.

One item is one Italian espresso — 25 mL in the cup — as the Istituto Nazionale Espresso Italiano defines it.
Passenger car tyre

One item is one kilogram of passenger car tyre.
Which is larger
The model cannot tell whether Coffee, one cup carries more harm than Passenger car tyre per kilogram: the range includes both possibilities.
Coffee, one cup against Passenger car tyre, per kilogram: ×2.0 as much, and very probably (nine times in ten) between ×0.73–×5.4.
In 0% of the runs calculated together, Coffee, one cup comes out above Passenger car tyre.
Calculated together: the same records of harm, the same split of each industry and the same world production in every run, and each product’s own list of materials. Seeing whether two separate ranges overlap would prove nothing either way.
The reason they differ
Deaths per kilogram of each product, by what carries them, with the largest difference first.

By the money method
- Coffee, one cup — 4.2 × 10⁻⁷ per €1,000 spent in its industry(2.8–6.2 × 10⁻⁷)MEDIUMS-CONS · run 2151 · methodology v0.1 · data dv-20261007-44r

Shown, not ranked. Measured per euro, most industries are too close to tell apart, and two products from the same industry always get the same figure per euro.
What this figure is not
Production phase only. Harm from using the product — driving the car, charging the phone — is not in this figure.
