Carbon calculator (business-friendly)
Two modes: a quick company estimate (easy inputs) and a precise mode (kWh/km). Both are transparent about assumptions.
Quick mode is designed for sponsors/SMEs who don’t have bills to hand.
It uses sensible defaults that you can edit in the assumptions section below.
Company inputs (annual)
Use rough numbers. You can refine later in precise mode.
headcount
choose a typical office profile
count of vehicles
annual km each
count of vehicles
annual km each
annual flights (all staff)
per flight (default 800km)
annual flights (all staff)
per flight (default 6000km)
Want higher accuracy? Switch to Precise and enter your bill totals / mileage.

tonnes CO₂e per year (estimate)
Breakdown
Tonnes CO₂e (tCO₂e)
Next step: Use this number to start the conversation, then move to a reduction plan and
discuss partnership support for land stewardship.
Assumptions (editable)
These are generic defaults. Replace with your preferred sources for formal reporting. The goal here is quick understanding and honest ballparks.
All factors are in kg CO₂e per unit. Update and recalculate.
