Introduction Background Note
5.The carbon price floor (CPF) came into effect in Great Britain in April 2013. It is designed to provide an incentive to invest in low carbon generation, promoting energy efficiency and the use of renewable energy, in order to help meet the UK’s international and domestic targets for cutting emissions of greenhouse gases.
6.CPF is a tax on fossil fuels (gas, liquefied petroleum gas and solid fuels), used to generate electricity. It is made up of the price of carbon from the EU Emissions Trading System (EU ETS) and the headline CPS rate which is the UK-only additional tax per tonne of carbon emitted in the power sector. The headline CPS rate is used to set the individual CPS commodity rates - for fuels covered by CCL these are known as the CPS rates of CCL and are legislated for in the Finance Act.
7.The CPS rates of CCL are legislated two years in advance based on a rate per tonne of carbon set for that year by the Government. An error in published data resulted in the CPS rate for coal and other solid fossil fuels being set too high for 2014-15 and 2015-16 when the rates were legislated in Finance Act 2013.  Data on the carbon content of coal used in UK power stations has been significantly improved and consequently the rates have been corrected, bringing them into line with the rate per tonne of carbon, and ensuring that they are proportionate with the CPS rates on other taxable commodities.
