Energy regulator Ofgem has announced that it will implement a rating scheme under which consumers and businesses will be able to compare the environmental credentials of green energy deals.
A rating of between one to five stars will be awarded to all green tariffs - and these scores will be made available to businesses and domestic customers looking to reduce their carbon footprint. The system will also extend to low carbon technologies such as combined heat and power schemes.
"More and more people want to go green, but they need to be sure that what they're doing is making a real difference," minister of state for climate change and environment, Ian Pearson, commented.
"Green tariffs have the potential to be a real force for good, and I'm delighted that the Energy Saving Trust (EST) and Ofgem are doing this much-needed work that will give consumers clear, accurate information on the options that are available to them."
Ofgem and the EST says that it will look to work with consumers and the energy industry as it forms its guidelines - which should be in place by September.
