The UK produced more carbon emissions last year despite the implementation of the European Union (EU) carbon trading scheme.According to figures revealed in Brussels reported by the Guardian, the UK's output increased by 2.2 per cent, while Europe saw an overall increase of 0.68 per cent, which translates to 16 million tonnes of CO2.Greenpeace has criticised the government's claim that the scheme is a success. Robin Oakley, head of the campaigning group's climate campaign, said that the only thing of import is the amount of CO2 being emitted into the atmosphere and pointed to the creation of new coal-fired power stations as an example of where it may be failing.He said: "It does not sound credible to call the emissions trading scheme a success when we have seen a proposal for a new coal-fired power station in Kent."It is not sending a strong enough signal to the power companies."The EU Emissions Trading Scheme puts a price on the carbon used by businesses and essentially creates a market for the substance. It aims to limit the amount of carbon emitted into the atmosphere.
