Mr. Robert Watt:

When it comes to looking at detail of the climate impact on policy changes, work has been done - more needs to be done - on establishing exactly what the climate impact would be and the cost of those policies. The technical research and modelling group, TRAM, is looking at that in detail. It is fair to say that a good deal of work needs to be done to establish across the system the initiative that will give the greatest bang for our buck, which will reduce emissions and at what cost? A good deal of work needs to be done within individual Departments. For example, within the retrofitting space, what types of initiatives will move us forward in terms of improving the energy efficiency of the housing stock? It is not a straightforward issue. It is a question of financing and whether households have the ability to raise the money required. Are they motivated? Do they see the benefit of retrofitting? Are they willing to overcome the hassle of retrofitting their homes? There is a variety of financial and other barriers that would impact, so it is up to the Department to establish the best options and then debate the case for funding. Within the envelopes we have set out there is significant funding, for example in respect of retrofitting.
