The right hon. Gentleman said that he was not quite sure why burning wood was any better than burning other things, because the emissions are similar. If my hon. Friend the Member for Richmond Park (Zac Goldsmith) were here, he would make the point that we have to be extremely careful about how we calculate the carbon footprint of some supposedly renewable fuels, because if we cut down virgin rainforests to grow things that are then pelletised and burned, the overall genuine carbon footprint is much worse than people like to pretend.
However, my hon. Friend would also make a sharp distinction between what I think is called long-cycle carbon—in other words, fossil fuels, where carbon has been locked away for millions of years, are a net release that makes an overall difference to the level of carbon—and short-cycle carbon, which is a sort of short-term recycling whereby things are grown in the course of our lifetime and burned. I will not tempt your patience, Madam Deputy Speaker, by going into the detail of the level of greenery, but I hope we can all agree that this scheme, with all its manifest flaws, intended to pursue a noble purpose.
Before I go on to the details of the RHI scheme, I will address a few other points. The hon. Member for Belfast East (Gavin Robinson) asked a series of questions about Northern Ireland housing associations and, I think, was hoping to pin us down on when a piece of legislation might be introduced. I want to reassure him—my right hon. Friend the Secretary of State made this point, but I will repeat it—that the Government will take that forward as soon as parliamentary time allows.
The hon. Member for Rochdale (Tony Lloyd) asked about the stronger towns fund and said that he did not feel he had enough of an answer yesterday; I want to ensure that we try to provide that today. He will be aware that the Secretary of State for Housing, Communities and Local Government made an announcement yesterday. The Treasury will apply the Barnett formula in the normal way and confirm the funding for each region in due course. We do not know that yet, but it will come out, and we will seek to ensure that towns in Northern Ireland, Wales and Scotland can benefit, building on the success of the Government’s growth and city deals.
The hon. Gentleman also asked about the applicable costs of the RHI scheme. I will address that specific item before coming on to the broader points. The scheme guidance, which I am sure we are all itching to go through in huge detail, has been published, and it sets out clearly the eligible costs. They are primarily the costs of the boiler. He mentioned costs to do with installation, pipework and the like, and some of those are included as well. Interest costs on borrowing are apparently not included as an eligible cost in this scheme. I wanted to share that with everybody, so that we have a shared fact base before we go into Committee and the detail of the amendment tabled by the Chairman of the Northern Ireland Affairs Committee, my hon. Friend the Member for South West Wiltshire (Dr Murrison).
Questions have been posed about the up-front payments and how they would be calculated for people who wanted to opt out of the scheme because they felt that if they remained in it, they would lose out too badly. Straightforwardly, an individual’s costs—that means the cost of installation, the capital cost of the boiler and other eligible installation and running costs—will all be included, and they will be reimbursed up to the 12% target rate of return for the revised scheme. All the additional costs of the renewable technology above a fossil fuel one will be reimbursed. That is crucial, because a number of Members have raised questions about what happens to people who are worried that they are going to lose out. The hon. Member for Strangford (Jim Shannon) read out an email he received from someone with precisely those concerns. If they are concerned that it will no longer be economic for them to stay in the scheme, they can opt out. It will be a free option for them, and they are guaranteed to have made 12% on their money if they decide to opt out at that stage.
