Butter

One kilogram of butter from cow's milk

This page shows what the product is made of and where each figure comes from. It does not show a death toll. The toll is calculated from this list of materials, and will be published only once it has a range and the model has passed its test on past years.

Butter from whole cow's milk at France's extraction rate, 4.6 kg of butter per 100 kg of milk. Milk is not in the materials register — livestock there is meat — so the milk is carried as an unregistered input: its mass is counted and its farming reaches no harm yet. That gap is why the grade is LOW.

The human cost, per item

One item is one kilogram of butter from cow's milk. Scenario Arms and resources, 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.

Deaths and injuries at work in these figures come from the 53 countries that reported work deaths and the 52 that reported work injuries for 2023.

Harm at work is counted as each country reports it to the UN’s labour statistics (ILOSTAT), and never estimated for a country that did not report: such a country is missing from that year, not counted as zero. So when two years’ figures differ, part of the difference can be a change in which countries reported. The model’s own year-to-year checks compare only countries that reported in both years.

The money method — per €1,000 spent

Two methods, never added together. The materials method counts only what the product’s list of materials reaches, so it is a floor. The money method counts the whole supply chain of the industry for each euro spent, so in principle it misses nothing — but it cannot see what this particular product is made of.

In human terms

One death for every 7.7 million – 42 million items.

By the money method, about €590 million – €1.4 billion of spending in its industry for each death.

Rounded so that it stays within the range, so the sentence never claims more than the range does.

Under each scenario

Five answers to how much of the harm counted in a place is linked to its economy. Same product, same year, same trade table: only the rule for linking harm to the economy changes.

What it is made of

Each line is one part of one kilogram of butter from cow's milk: how much of it goes in, how much had to be produced to get that much (some is wasted along the way), and where the figure comes from.

France: butter of cow milk 4.6% of whole fresh milk (printed p. 545), so 1 / 0.046 kg of milk per kilogram Registered as the material `milk` on 2026-09-18, when FAO's Milk, Total production entered the register: this line reached no supply chain until then, and it is why a croissant traced 15%.

Down to raw materials

The whole chain worked out — everything one kilogram of butter from cow's milk needs, through every product in between, with all the waste along the way included.

Down to raw materials
Input Per item
Milk 21.7 kg

An input marked “not in the register” is counted by weight but is not yet linked to any supply chain. Services such as transport appear as the euros, or tonnes carried a kilometre, that the list of materials gives them.

How much of it is known in detail

100% of this product’s weight is listed in detail in its own list of materials.

Its whole chain uses 21.7 kg of materials, waste included. 100% of that is raw materials the model knows — the part it can trace harm to — 0% is inputs not yet on the list, and 0% is an openly stated remainder.

In the table of what industries buy from each other it belongs to “Manufacture of food products; beverages and tobacco products” (FIGARO industry C10-12).
