My Lords, if the Government’s environmental ambitions are to mean anything, they have to be matched by action. In that context, does the Minister agree that a good start would be for the Government to back the Domestic Premises (Energy Performance) Bill introduced by my noble friend Lord Foster of Bath with cross-party support? Does the Minister understand that if the Government are unwilling even to support such a modest but very important measure such as this, their talk of environmental ambitions will ring very hollow indeed?
