# How do Shahabad stone cutting and polishing units work out their carbon footprint?

Canonical: https://senseible.earth/answers/shahabad-stone-polishing-unit-electricity

Most of it is electricity for gang saws, cutters and polishers, at 0.710 kg CO2 per kWh, plus diesel for quarry machines and trucks. Divide by square metres of finished slab. Record units from bills and output from sales.

## Sources

- Electricity for cutting and polishing.
- Diesel for quarry excavators, compressors and loaders.
- Truck transport to buyers, if asked.

## Per square metre

Divide by finished area at a stated thickness. Breakage and rejects raise the figure, so use good output.

## Reducing it

Rooftop solar and efficient motors cut the largest share; show their effect against a recorded baseline.

## What Senseible does here

Senseible reads fuel, electricity and production documents into dated, fingerprinted plant records, so the monthly intensity behind a figure can be traced to its source.
