CocoonCarbon - Formulas and assumptions used for the calculation of Estimation of CO2e emissions are based on the framework of accredited sources such as the Greenhouse Gas Protocol – Category 9 (Downstream) & Category 4 (Upstream) Scope 3.

Distances may differ as many factors can change the direction of travel. We will either use Actual Distance or Great circle distance (GCD - Also known as direct distance or ‘as the crow flies’)

Weather, atmospheric conditions, equipment age and other factors can affect getting an accurate calculation.

Freight is based on averages using 2020 GHG Protocol and Methodology

The C02Emission we report to be absorbed by trees is an estimation and taken from various accredited sources. The assumption is a tree will be fully formed.

• CO2e = Carbon Dioxide equivalent
• NOx = Nitrogen oxides
• PM = Particulate Matter Emissions
