# What is the carbon footprint of a truck body built in Namakkal, and where does it come from?

Canonical: https://senseible.earth/answers/namakkal-truck-body-builder-steel-scope-3

Mostly from the steel. A body using 2 tonnes of steel at about 2.3 tonnes CO2 per tonne carries roughly 4.6 tonnes before your own welding, painting and power. Ask steel suppliers for their figure; use an average labelled as an estimate until they reply.

## Inputs

- Steel sheet, sections and tubes by weight, from invoices.
- Paint and primer, welding gas and electrodes.
- Electricity and diesel used in the shed.

## Lower it

Lighter designs with high strength steel cut tonnes per body, and buyers notice lower weight and fuel use.

## Example: one body

- 2.0 t steel × 2.3 t CO2/t = 4.6 t CO2
- Add your own power, diesel and paint

2.3 is an illustrative average for blast furnace steel; replace it with supplier data.

## 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 data is still missing.
