# How does a Sivakasi printer work out carbon per diary or calendar?

Canonical: https://senseible.earth/answers/sivakasi-diary-calendar-printer-carbon-per-copy

Add the press's energy for the job, then the paper, board and ink per copy with supplier or database factors, and divide by copies printed. Paper is a major line, so get the paper mill's figure if you can.

## Steps

Press, binding and finishing kWh for the job, x 0.710.

Paper and board tonnes, with the mill's figure or a named factor.

Ink and plates by kg.

Divide the total by copies delivered.

## Wastage

Count paper bought, not paper in the finished copies, so make-ready and trimming waste is included.

## 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.
