# How do I work out emissions from trucking Ballari iron ore to the port?

Canonical: https://senseible.earth/answers/ballari-iron-ore-trucks-to-port-emissions

Multiply tonnes carried by road kilometres and by a factor for the truck class, or use the diesel the transporter actually burnt times 2.68 kg CO2 per litre. If you pay the transporter, it is your Scope 3 category 4.

## Two ways

- Distance based: tonnes x km x factor per tonne km. The Smart Freight Centre India default for 30 to 50 tonne trucks is 0.0663 kg CO2e per tonne km.
- Fuel based: litres of diesel from the transporter x 2.68 kg CO2 per litre. Better when you can get it.

## Return trips

Ore trucks often return empty. Published tonne km factors usually include typical empty running; do not add the empty leg again.

## Rail

Moving ore to a rail siding and then by rail cuts emissions per tonne km sharply. Calculate each leg with its own mode factor.

## Illustrative trip to the port

- Load: 35 t; distance: 300 km
- 35 x 300 = 10,500 tonne km
- 10,500 x 0.0663 = 696 kg CO2e

Load and distance are illustrative; 0.0663 kg CO2e per tonne km is the SFC India default for 30 to 50 tonne trucks, well to wheel.

## 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.
