You are basing your analysis on the data for total CO2 emissions, which are naturally greater for larger buildings. This is clearly a less fair comparison, as comment #7 helps to explain. I did point out that many of the buildings with very high total emissions are hospitals, which may reflect their size.
So, despite what you say, I have actually got the facts straight and used the data which provides the fairest comparison.
thomasak001: Asks how can the Commons redact information so widely without being in contempt of last year's court decision forcing disclosure of MPs' expenses. The Commons did comply with that decision last year, which only concerned 14 MPs, by releasing all the data about them, including addresses for example. Parliament has since changed the Freedom of Information Act so that there is now no obligation to reveal MPs' addresses and other material which it is said could imperil their security. (It is not obvious how this can extend to the model number of a dishwasher).
jfpollard: Complains that the Commons Fees Office is escaping without criticism. One of the things I've found interesting from the Telegraph's coverage is the apparent inconsistency of attitudes adopted by the Fees Office. In some cases they clearly did battle with MPs to reduce their claims; in other cases they clearly encouraged MPs to put in dubious claims for well in excess of the MPs' intentions. This may reflect different approaches from different staff in the office. I've been told that some junior staff there sometimes felt that their superiors did not support them properly when they were trying to cut back an MP's claim.
splendidhashbrowns: Asks if you could you use an FOI request to find out what MPs actually spend their salaries on. The answer is no. The information about the money they claim for expenses from the House of Commons is held by the administration of Parliament and is subject to FOI because Parliament is. Individual MPs do not come under the Freedom of Information Act, and in any case what they spend their personal salaries on would generally be private information as it would be for any other public official.
