<aside> 💡 Estimating the carbon emissions of a shipment based on distance, cargo weight and mode of transport. Our calculations are based on the leading international standard for logistics emissions calculations, the GLEC Framework, and are audited and accredited by Smart Freight Centre.
Lune’s Smart Freight Centre audited & accredited calculations follow the GLEC Framework.

Also see our API documentation.
Our shipping emissions calculations follow both the GHG Protocol and the GLEC Framework. The calculations are done in a few steps. Let us first go through the request possibilities then define the steps we take to provide a calculation. Do take a look at our public API since it's a great way to check for the request possibilities.
Lune calculates carbon emissions based on 3 inputs:
**Route**(distance OR point A-B, in which case we calculate distance)
**Shipment**(mass in kg or metric tonnes OR number of TEUs with an optional cargo type specified)
**Method**(the transport method)
This mostly correlates to the 3 factors specified in the GLEC framework (See page: 24 onwards):
Weight = Shipment,
Distance = Route and
Tonne-kilometer = Method.
The steps we take to calculate the full Well-to-Wheel CO2e emissions are:
