DEFRA publishes annual statistics on UK carbon dioxide emissions, as well as verified emissions data and surrendered allowances under the EU emissions trading scheme. That information allows us to measure progress towards our emissions reduction targets.
It is clear that we. as a Government. need to do better in respect of the Government office estate. That is one of the reasons why in July last year we announced new sustainable operation targets for the Government estate, and why we have said that we want the Government Office estate to be carbon-neutral by 2012. To be honest, I think our performance to date has been a little disappointing. Although it has been good in places, it has been patchy, and the National Audit Office recognised that. We need to work harder at that, right across Government.
There are a number of issues around that point, but, broadly, the answer is yes. In some cases, lights need to be on at night for cleaning purposes, but the Government have been considering how cleaning can be undertaken in daylight hours. We can do more on optimising systems to switch off lights when buildings are not being used, and a programme of work has been implemented across Government.
