Emissions engine
Enter activity — litres, kWh, kilometres — and Tellus applies the official factor for the reporting year, using the methodology you choose. Prior years keep their own factors.
What’s inside
Convert activity to CO₂e using DESNZ, US EPA or IPCC factors — each a full CO₂e set with the right global-warming potentials. Your report states which you used.
Enter fuel used and get emissions back, using the year’s official factor.
By haul and cabin class, with radiative forcing included.
Round-trip distance by mode, gathered with an HR template or inputted directly into Tellus.
Fuel converts to kWh and emissions automatically.
Scope 2 uses the right grid factor for each location.
Each reporting year uses its own factor set, so comparisons stay honest.
Ready when you are
Map one figure to every framework, lock a reporting year, and hand your assurer a clean audit trail. A 30-minute walkthrough shows you how — walking through your own numbers.
