# How do I calculate the carbon footprint of BOPP packing tape per roll?

Canonical: https://senseible.earth/answers/bopp-tape-carbon-footprint-per-roll

Weigh the BOPP film, adhesive and paper core in a roll and multiply each by its supplier's per-kg figure. Add the coating line's fuel and electricity and slitting power, divided by rolls passed. Film and adhesive are usually most of it.

## Materials

- BOPP film by weight per roll, from width, length and micron.
- Acrylic water-based or hot-melt adhesive by dry weight.
- Paper core and printing ink for printed tape.

## Process

- Coating line with its drying oven, often heated by fuel.
- Corona treatment and rewinding.
- Slitting, shrink wrapping and cartons.

## Per roll

State width, length and film thickness with the figure, since rolls vary widely.

## Worked example: tape plant per roll (one month)

- Electricity: 40,000 kWh x 0.710 = 28,400 kg CO2
- PNG: 6,000 SCM x 2.05 = 12,300 kg CO2
- Rolls passed: 500,000
- Plant total: 40,700 / 500,000 = 0.0814 kg CO2 per roll
- Add film, adhesive and cores for the full figure

Inputs are illustrative; use your own bills and production records.

## What Senseible does here

Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.
