Whilst they are not all the same, signing up to such a tariff can be a good signal to the market and can often support the development of new renewable energy generation.

However, for the purposes of calculating your carbon footprint, the UK Government considers all energy tariffs the same. Physically the wires that transmit the energy to you do not distinguish between organically grown renewable electrons from dirty fossil fuel generated ones.

In order to consider yourself carbon neutral we would encourage you to include energy consumption as part of your footprint irrespective of what tariff you are on.
