How the Carbon Footprint Calculator works

Our free Carbon Footprint Calculator gives UK businesses a fast, indicative estimate of their annual greenhouse gas emissions across Scope 1, 2 and 3. Enter your energy use, business travel and a few company details, and you'll get an estimated tCO₂e figure benchmarked against your sector in under three minutes, using DEFRA 2026 conversion factors. It's free, instant and carries no obligation.

1

Enter your energy use

Add your annual electricity and gas consumption in kWh, or estimate it from your annual spend.

2

Add business travel

Include company car mileage and any domestic, short-haul or long-haul flights over the year.

3

Get your footprint

See your estimated tCO₂e, a Scope 1/2/3 breakdown and a sector benchmark, emailed straight to you.

What the Carbon Footprint Calculator covers

  • Scope 1 - direct emissions from natural gas and company vehicles.
  • Scope 2 - indirect emissions from the electricity you purchase.
  • Scope 3 - a selected slice of indirect emissions (business flights).
  • Sector benchmarking - how your per-employee intensity compares with similar UK businesses.
  • DEFRA 2026 factors - the UK government's official greenhouse gas conversion figures.

A free guide, not a compliance report

This is a free, basic tool. It gives an indicative estimate from the limited figures you enter and standard DEFRA averages, so treat the result as a guide only. It is not a compliant, audit-ready carbon account and should not be used for statutory reporting.

For a complete, accurate and compliant view of your emissions, our EaaSi® Carbon software and specialist team go far further: full Scope 1, 2 and 3 mapping from your primary data, SECR and ESOS-ready reporting, science-based and net-zero target setting, and a costed reduction roadmap. It turns a rough estimate into a verified, business-grade carbon account you can stand behind.
