# What is the carbon footprint of agricultural shade net per square metre?

Canonical: https://senseible.earth/answers/shade-net-carbon-footprint-per-square-metre

Shade nets are knitted from HDPE monofilament, so the polymer is most of the footprint. Extruding and knitting add electricity at 0.710 kg CO2 per kWh. Weigh grams per square metre and multiply by an HDPE factor, then add process energy.

## Parts

- HDPE resin, by grams per square metre.
- UV stabiliser and colour masterbatch.
- Extrusion and knitting power.

## Life

A net that lasts five seasons spreads its footprint over five crops. Ask for the rated life with the figure.

## 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.
