Carbon Footprint Calculator

Enter a few annual figures to estimate your company’s Scope 1, 2 and 3 carbon footprint in tonnes of CO₂e.

Estimated footprint

Enter at least one figure to see your estimated footprint.

Estimates use indicative average emission factors and are for guidance only — not a compliant inventory.

How it works

  1. 1

    Enter your approximate annual figures for the activities below.

  2. 2

    We apply indicative emission factors to estimate kg CO₂e per activity.

  3. 3

    You get a total footprint split across Scope 1, 2 and 3.

Frequently asked questions

How accurate is this carbon footprint calculator?

It produces a directional estimate using indicative average emission factors. A compliant footprint uses source-specific AR4/AR5 factors, activity data, and a defined boundary — which Clidapt automates inside the app.

What are Scope 1, 2 and 3 emissions?

Scope 1 is direct emissions from sources you own (fuel, vehicles). Scope 2 is indirect emissions from purchased energy (electricity, heat). Scope 3 is all other value-chain emissions (travel, purchased goods, waste).

Is my data stored?

No. This tool runs entirely in your browser and does not save or transmit your figures.

Want an audit-ready footprint?

Clidapt measures your real Scope 1, 2 & 3 footprint and drafts the report for you.
