Electricity tariffs with 'genuine benefits' for the environment will be acknowledged by a new certification scheme

The 'green energy certified' label - awarded after assessment by an independent panel - will implement Green Supply Guidelines published by energy watchdog Ofgem last year.

Cuts in CO2

Under the new scheme, energy suppliers will need to demonstrate their energy tariffs result in a reduction of a certain amount of carbon dioxide emissions. 

This must be in addition to any activity energy suppliers may have already undertaken to meet the Government targets for sourcing more renewable electricity and reducing household carbon emissions.

If you're looking to switch to an energy tariff with more environmental credentials Which? Switch can help take the hassle out of changing energy supplier. Those switching with Which? Switch between January 1 and October 21 2009 saved an annual average of £263.

Green energy

Only 2% of Britons currently buy green energy, but it's hoped the certification scheme will result in a trustworthy label that will convince many others to go green.

Customers who do choose a green energy tariff will know they will be supporting energy suppliers making a certain effort to cut carbon emissions.

Seven energy suppliers are currently participating in the scheme and have had energy tariffs assessed by the panel, chaired by leading sustainable energy expert, Solitaire Townsend. Details of newly certified tariffs are available at the Green Energy Scheme website.
