# How does a dye intermediate unit in Vatva count CO2 from its boiler and thermic fluid heater?

Canonical: https://senseible.earth/answers/vatva-dye-intermediate-unit-boiler-co2

Add up every fuel burnt: coal, briquettes, natural gas or furnace oil in the boiler and thermic fluid heater. Multiply each by its calorific value and factor. Steam bought from a common facility is not your Scope 1, but its emissions are a cost your buyer may ask about.

## Sources

- Boiler fuel.
- Thermic fluid heater fuel.
- Grid electricity for reactors, filters and dryers.
- Process emissions, if any reaction releases CO2.

## Records

Fuel invoices, stock registers and gas bills, matched to production batches.

## Per kg of product

Divide by kilograms produced, or allocate by batch steam use when several products share the boiler.

## What Senseible does here

Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
