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