Work out your electrical equipment (WEEE) recycling emissions
= 4.7 kg CO2e in 2026 (Scope 3)
Each tonne × 4.6536 kg CO2e, the 2026 UK government (DESNZ) factor.
That is one line of your footprint. Want the whole thing done for you?
Carbon Recycling holds every UK government factor for every year, works out each line from your bills, mileage and travel, and writes your Carbon Reduction Plan and SECR report.

Electrical equipment (WEEE) recycling emission factor by year

|---|---|---|
| 2026 | 4.6536 | -0.7% |
| 2025 | 4.6857 | -26.9% |
| 2024 | 6.4106 | -69.9% |

| 2020 | 21.317 | -0.2% |
| 2019 | 21.354 | – |
Total kg CO2e for the seven greenhouse gases, from the official DESNZ files for each year. 2026 factor ID: 20_503_5330_15_1. Where a factor jumps sharply between two years, it is usually because DESNZ changed its method or data source, not because the activity itself changed.
Worked example
Take an office recycling a tonne of old computers, screens and phones a year. 1 tonnes × 4.6536 kg CO2e = 0.00 tonnes CO2e, reported as Scope 3, category 5 (waste generated in operations).
How to report it
Old IT and electrical equipment is WEEE. Your IT disposal company's certificate of recycling or destruction usually shows the weight.
Waste is Scope 3 category 5, waste generated in operations, which PPN 006 Carbon Reduction Plans must include.
Where the data comes from
You'll usually find it in your waste contractor's reports or waste transfer notes, in tonnes. Keep the source documents: anyone checking your Carbon Reduction Plan or SECR report may ask how each figure was worked out.
