How It Works
The “How It Works” pages contain information about the data underlying the 360°carbon
The majority of our carbon emissions factors
come from the UK Government – Defra. These factors are published annually and we aim to always add the latest factors within a month of their release (subject to amendments by Defra themselves of the factors).
In simple terms, proxies
are a way of relating the amount spent on an activity to the carbon emissions associated with that activity. All of our proxy factors (used for the “Expenditure” category) are derived from data published by Defra.
