I congratulate the hon. Gentleman on securing this debate, which is important to my constituents because an application is in train for a new biomass plant in Davyhulme. One issue is that not all the biomass that will be used is necessarily virgin forest. In the case of the Davyhulme plant, it is proposed to recycle already-used woods. Does he accept that if those woods have been treated with varnishes and paints, it creates a rather different picture for the potential carbon impact?
