Petrol car
One midsize petrol car of 1,385 kg
This page shows what the product is made of and where each figure comes from. It shows no death toll. The toll is computed from this bill of materials from session 19, and published only once it has an uncertainty interval and has passed a backtest.
A midsize internal-combustion sedan, the average of three high-market-share US models measured part by part in the A2Mac1 teardown dataset and published by Argonne for the GREET vehicle cycle. 1,385 kg: 862 kg of steel, 177 kg of aluminium, 210 kg of plastic. Production only — the fuel it burns for a decade is not here, and for a car that is most of its toll (Phase E).

What it is made of
Each line is one component of one midsize petrol car of 1,385 kg: how much of it goes in, how much had to be produced for that, and where the figure comes from.

Table A-1, average vehicle component weight based on the A2Mac1 dataset: Car: 1900.07 lb of steel summed over all 29 component rows, which is 861.9 kg of the car's 1385 kg |

Average plastic — polymers not named by the source part |

Table A-1, average vehicle component weight based on the A2Mac1 dataset: Car: 463.28 lb of average plastic summed over all 29 component rows, which is 210.1 kg of the car's 1385 kg. The source does not name the polymers. The catalogue's plastics product has no sourced composition yet, so this mass is carried by name and reaches no supply chain rather than through an empty chain |

Table A-1, average vehicle component weight based on the A2Mac1 dataset: Car: 389.43 lb of aluminium summed over all 29 component rows, which is 176.6 kg of the car's 1385 kg (295.51 lb cast, mostly wheels, and 93.92 lb wrought) |

Rubber part |

Table A-1, average vehicle component weight based on the A2Mac1 dataset: Car: 110.55 lb of rubber summed over all 29 component rows, which is 50.1 kg of the car's 1385 kg. Tyres are inside this figure, so the catalogue's car tyre is NOT also counted here: that would be the same rubber twice |

Table A-1, average vehicle component weight based on the A2Mac1 dataset: Car: 75.84 lb of copper and brass summed over all 29 component rows, which is 34.4 kg of the car's 1385 kg. Brass is copper and zinc; the source does not split them |

Down to raw materials
The whole chain multiplied out — everything one midsize petrol car of 1,385 kg needs, through every intermediate product, with every loss on the way included.
| Input | Per functional unit |

| Bauxite | 707 kg |
| Coal and lignite | 509 kg |
| Copper | 34.4 kg |
| Iron ore | 978 kg |
| Silica sand | 23.8 kg |
| Average plastic — polymers not named by the source (not in the register) | 210 kg |
| Electricity, electric arc furnace route (not in the register) | 165 kWh |
| Glass fibre-reinforced plastic (not in the register) | 12.8 kg |
| Limestone (not in the register) | 186 kg |
| Limestone (calcium carbonate) (not in the register) | 7.27 kg |

| Soda ash (sodium carbonate) (not in the register) | 7.80 kg |
An input marked “not in the register” is counted by mass and reaches no supply chain yet. Industries appear as the euros or tonne-kilometres the bill of materials gives them.
How much of it is explicit
100% of this product’s mass is explicit in its own bill of materials.
Its whole chain draws on 2.99 t of materials, losses included. 75% of that is registered raw materials — the part the model can trace harm to — 25% is inputs not yet in the register, and 0% is a declared remainder.
In the input–output model it belongs to “Manufacture of motor vehicles, trailers and semi-trailers” (FIGARO industry C29).

The number this page does not show
The harm in this chain is not shown.
The model allocates the harm counted where each raw material is produced to the products that use it. That number is a count of people with a run behind it and no uncertainty interval yet, and nothing of that kind is published before the backtest of session 21. What this page can show without it is the structure: what the product is made of, and where each part of that knowledge comes from.
