What carbon data can a Kutch salt works give a soda ash or chlor alkali buyer?

Diesel or electricity for brine pumps, diesel for harvesting and loading, and freight to the plant, per tonne of salt. Evaporation itself uses sunlight, so the figure is small. Buyers mainly want it measured so their Scope 3 is complete.

Per tonne

1. Pump energy: kWh from bills, or diesel litres.
2. Harvest and loading diesel.
3. Divide by tonnes dispatched.

Freight

Truck or rail to the chemical plant, by distance and load. Often larger than the salt works itself.

For the buyer

Salt is Scope 3, category 1 for the soda ash or chlor alkali plant.

What Senseible does here
