SCOPE 1 · 2 · 3

How company emissions are organised.

Scope 1 covers direct emissions from sources you own or control — fuel and company vehicles. Scope 2 is the indirect emissions from the electricity you purchase. Scope 3 is everything else in your value chain — business travel, purchased goods and services, and more — and for most companies it’s the largest and most overlooked share. This calculator gives a directional Scope 1/2/3 estimate; reduce what you can, then offset the remainder with an audit-ready certificate.

BUSINESS CALCULATOR FAQ

Common questions.

How do I calculate my company’s carbon footprint?

Estimate emissions across three scopes — Scope 1 (direct fuel and fleet), Scope 2 (purchased electricity), and Scope 3 (business travel and supply chain). This calculator gives a directional total; for audit-grade reporting our business team builds a full inventory with you.

What are Scope 1, 2 and 3 emissions?

Scope 1 is direct emissions from sources you own or control (fuel, company vehicles). Scope 2 is indirect emissions from the energy you purchase. Scope 3 is all other value-chain emissions — business travel, purchased goods and services, and more — and is usually the largest.

Which scope is usually the biggest?

For most companies Scope 3 dominates, because it captures travel and the supply chain. It’s also the most commonly overlooked, so it’s worth estimating carefully.

Is this suitable for ESG reporting?

It’s a directional first pass. For CSRD, CDP or TCFD-grade disclosure, business plans include an audit-ready ESG summary with serial numbers and registry links, and we can build a full inventory with you.
