How does a buyer count Kuwaiti polyethylene in Scope 3?

Multiply tonnes bought by a per tonne footprint for that grade, ideally from the producer, cradle to gate. Polyethylene is not a CBAM good, so this is a Scope 3 figure, not a border charge. Without producer data, use a database value for gas based ethylene and say so.

What to ask

Records

Purchase invoices with tonnes per grade, and the producer named on the delivery note.

Your own share

Add the power for extrusion or moulding to get a footprint per tonne of finished product.

What Senseible does here

Senseible turns supplier invoices into a Scope 3 record with the supplier, quantity and factor behind every figure, so you can see which supplier data is still missing.
