Cameron has expressed his opposition to Green Taxes in Prime Minister's Questions in October 2013, stating that, in order to cut taxes generally, he would 'roll back' the Green Tax. The 'Big Six' energy companies are advocates of this, according to the Express, in order to avoid Labour's plans for an energy price freeze, which would 'deter much-needed investment' from the energy industry (according to "The Daily Telegraph"). Labour – on the other hand – implied that Cameron was being hypocritical, because even though he was proposing reducing renewable investment, he had said previously in the 2010 election campaign, '...vote blue to go green...' (in other words, that the Conservatives would be eco-friendly).
