British Gas has two green tariffs:

The Zero Carbon tariff is designed to help reduce the impact of your home’s annual carbon emissions and includes green source, green fund and carbon offset elements. It is only available to dual fuel customers of British Gas. An average customer– using 3,300 kWh of electricity and 20,500 kWh of gas – will pay a premium of around £84 per annum. British Gas will match 100% of the electricity you use with a supply of renewable power back into the electricity grid. It will retire 12% of Renewable Obligation Certificates (ROCs) over and above its statutory obligations. This removes ROCs from the market, increasing the price of ROCs, which in turn increases the prices that renewable generators receive. The company will also make a £10 contribution to the non-profit British Gas green fund, which is focussed on helping schools to reduce their CO2 emissions. The carbon offset element of the tariff is Kyoto compliant and will meet the new Defra requirements. Customers will be included in the British Gas green community and receive ongoing advice and newsletters. They will also be encouraged to reduce their energy consumption by completing an Energy Savers Report at www.Britishgas.co.uk/esr.

Future Energy is a green source and a green fund electricity tariff, attracting an average premium of £36 per annum. This premium will be invested in the non-profit British Gas green fund, with £10 of the contribution going towards helping UK schools to reduce their CO2 emissions and the remainder to be invested in the development of new renewable technologies and resources. British Gas will match 100% of the electricity you use with a supply of renewable power back into the electricity grid.
