Supplementary memorandum from the Department for Environment, Food and Rural Affairs (DEFRA)
DEFRA's response to the questions that required further consideration is as follows:
The Cabinet Office was unable to provide data on their timber purchases for the Greening Government Report in question. I understand that the Cabinet Office responses to these questionnaires include No. 10 Downing Street.
Of the 305 new doors in the Ripley Building, the vast majority is due to have a french polish finish, although a handful (ie those adjacent to original doors that had subsequently been painted) will be painted.
The doors in Kirkland House are generally made from plywood but do have small amounts of sapele used for the lippings (ie the edges round the doors). They, as well as the sapele door frames, will be painted.
The Forestry Commission confirms that UK forests produce approximately 15 per cent of the timber consumed in the UK. There is no way at present to link production to Government use as a consumer. If Government consumption mirrors general consumption then it would not be unreasonable to estimate that 15 per cent of the timber purchased by Government comes from trees grown and harvested in the UK.
