Energy regulator Ofgem has launched a new green energy certification scheme to help consumers compare energy providers.
The new scheme is designed to help customers identify which electricity tariffs offer the best environmentally-friendly benefits.
Energy suppliers will have to provide an independent panel of experts with proof that they are doing more than required to meet existing government targets on sourcing more renewable energy and reducing household carbon emissions.
The expert panel, which is chaired by sustainable development expert Solitaire Townsend, has already assessed the tariffs of British Gas, E.On, EDF Energy, Good Energy, RWE Npower, Scottish and Southern Energy and Scottish Power.
For domestic green tariffs, energy suppliers have to reduce a minimum of one tonne of carbon dioxide equivalent emissions a year if the environmental activity is carbon offsetting.
Ofgem hopes the scheme will remove confusion about the eco credentials of energy tariffs and encourage customers to switch energy providers in order to cut their carbon footprint.
