How do I calculate the carbon footprint of a mosquito net?
Weigh the polyester or polyethylene netting per net, multiply by the yarn supplier's figure, and add treatment chemicals if any, then add knitting, cutting and stitching energy per net made.
Material
- Polyester or polyethylene yarn.
- Insecticide treatment if the net is treated.
- Border fabric, thread and packing.
Process
- Warp knitting the netting.
- Heat setting and treatment.
- Cutting, stitching and packing.
Per net
Report per net by size and fabric weight.
Worked example: plant energy per net (one month)
- Electricity: 20,000 kWh x 0.710 = 14,200 kg CO2
- Nets made: 30,000
- Plant total: 14,200 / 30,000 = 0.473 kg CO2 per net
- Add yarn and any treatment for the full figure

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.
