This carbon calculator let’s individuals measure their yearly carbon (CO2e) footprint and can be used for both private citizens or staff members of a company.
Simply type in each segment based on annual demand.
How to enter electricity use.
Standard Grid Electricity:
Use the default value provided. This segment uses the most up to date UK grid mix CO2e per kWh factor.
Certified Green Tariff:
If your supplier provides proof (e.g. REGO certificate), you can enter 0.
(Note: The actual electricity still comes from the grid, so proof is essential.)
Onsite Renewables (e.g. Solar Panels):
Only enter the grid electricity you actually use.
If your building is energy neutral or exports more than it uses, enter 0 rather than a negative value.
(Exported energy doesn’t count as a carbon saving because it’s already part of the grid mix.)
The calculator’s total is fixed on a default setting of a plant based diet, assuming that all the other segments other than this one are optional.
