In April 2005, advisers to British Prime Minister Tony Blair were suggesting that constructing new nuclear power stations would be the best way to meet the country's targets on reducing emissions of gases responsible for global warming. The energy policy of the United Kingdom has a near-term target of cutting emissions below 1997 levels by 20%, and a more ambitious target of an 80% cut by 2050. In November 2005 the Government announced an energy review, subsequently launched in January 2006, to "review the UK's progress against the medium and long-term Energy White Paper goals and the options for further steps to achieve them".
