The future of nuclear power in the United Kingdom is currently under review. The country has a number of reactors which are currently reaching the end of their working life, and it is currently undecided how they will be replaced. The UK is also currently failing to reach its targets for reduction on CO2 emissions, which situation may be made worse if new nuclear power stations are not built. The UK also uses a large proportion of gas-fired power stations, which produce half the CO2 emissions as coal, but there have been recent difficulties in obtaining adequate gas supplies. In 2016 the UK government committed to support the new Hinkley Point C nuclear power station.
