How It's Calculated

Where the Figures Come From

ABLE ecosystems builds this footprint directly from supplier-submitted evidence — utility bills, chemical recipes, safety data sheets, and delivery receipts — allocated to each production step by that supplier's own metered contributions. Where a supplier hasn't yet submitted metered data, an industry-average (Ecoinvent) figure for that process stands in instead.

Every ingredient's own footprint ladders up into the components that use it — so a raw material's impact folds into the material made from it, which folds into the finished Balloon Vest | Jet Black | 26F-CHL-001-DFT-30-OPC-230 shown here.

Each Supplier's Part

Every step in the journey has its own figure, per kilogram of the material made at that step. A kilogram of the finished Balloon Vest | Jet Black | 26F-CHL-001-DFT-30-OPC-230 does not carry a kilogram of every material in it: it carries its share of each, as its composition says, and of each of their ingredients in turn.

So a step's part of the footprint is its own figure times how much of its material ends up in the garment, and a supplier's part is the sum of its steps. Added together, every supplier's part is the total shown in the Overview — which is why the report can say what share of it each supplier is.

A material used in more than one place in the chain counts once for every place it is used. A step whose supplier is not named still counts, under the step rather than under a name.

Per Component and Per Kg

Per Component is the figure for one Balloon Vest | Jet Black | 26F-CHL-001-DFT-30-OPC-230 at its recorded weight. Per Kg is the same figure for a kilogram of it.

A supplier's part, and its share of the total, are always of the finished Balloon Vest | Jet Black | 26F-CHL-001-DFT-30-OPC-230.
