# How does a Jharsuguda fabricator count the aluminium sections it buys?

Canonical: https://senseible.earth/answers/jharsuguda-fabricator-aluminium-sections-scope-3

Aluminium sections bought are purchased goods, Scope 3 category 1: kilograms times a factor per kg, ideally the extruder's own figure. Your workshop's electricity and gas are Scope 2 and 1. The metal is usually far larger than your fabrication energy.

## Two parts

- Bought metal: kg from invoices times the extruder's CO2 per kg, or a named database value if they have none.
- Your own work: cutting, drilling, powder coating ovens and site power, from bills.

## Ask the extruder

Primary aluminium from captive coal power and recycled aluminium differ by several times. The supplier's figure, with its share of recycled metal, matters more than anything else.

## Offcuts

Offcuts sold back to scrap dealers do not reduce what you bought; report them separately.

## What Senseible does here

Senseible reads the energy invoices behind the making stage into a fingerprinted Scope 1 and 2 record, and keeps material invoices on the Scope 3 trail. Material factors come from your supplier or a named database and are labelled with their source, so the product figure can be traced line by line.
