John Healey: All departmental travel is conducted in accordance with the Civil Service Management Code. The Treasury is contributing to the carbon offsetting fund, co-ordinated by the Department for Environment, Food and Rural Affairs, to offset emissions from flights on departmental business from April 2006. The Department also encourages the use of video conferencing to reduce official travel.
Mr. Peter Ainsworth: To ask the Chancellor of the Exchequer if he will convert the figure of $85 per tonne of carbon in 2000, given on page xvi of the Stern Review as the social cost of carbon, into the equivalent expressed as per tonne of carbon in pounds sterling at current prices; and what this figure would be adjusted to take account of Stern's finding that the social cost of carbon rises over time. 
John Healey: The Government Economic Service working paper Estimating the Social Cost of Carbon Emissions suggests illustrative values for the social damage cost of carbon that can be used to estimate the monetary value of impacts once they have been quantified. Though subject to significant levels of uncertainty, this paper suggested £70/tC, within a range of £35 to £140/tC, as an illustrative estimate for the global damage cost of carbon emissions, rising by £1/tC per year in real terms to reflect the increasing marginal cost of emissions over time. We are in the process of re-examining the issue of the social cost of carbon, with the Stern Review on the economics of climate change informing our conclusions.
Colin Challen: To ask the Chancellor of the Exchequer how many tonnes of carbon dioxide emissions it is estimated will be saved as a result of the rise in (a) fuel duty and (b) airport passenger duty announced in the pre-Budget report. 
John Healey: Inflation based increases are already factored into Government forecasts for carbon emissions and therefore this increase in fuel duty will not impact on this. However, if rates had been frozen, we forecast that carbon emissions would have been 0.16MtC higher in 2010-11 (or 0.15MtC higher on average in each of the next five years).
Ed Balls: In 2005-06, 935,000 Child Trust Fund vouchers were issued to eligible children. In 2006-07, 135,000 Child Trust Fund vouchers have been issued to eligible children to June 2006, as set out in the latest published figures which are published quarterly at:
Mr. Francois: To ask the Chancellor of the Exchequer what percentage of eligible children in households in the bottom income decile in the UK have (a) received child trust fund vouchers and (b) had child trust fund accounts opened for them. 
All eligible children will have an account opened for them. If the child's parents do not use the Child Trust Fund voucher within 12 months to open an account, HMRC will open an account on the child's behalf.
Dr. Francis: To ask the Chancellor of the Exchequer if he will consider the merits of extending tax relief for child care vouchers to cover the care of adults; what assessment he has made of the potential effect of this change on the employment of (a) carers, (b) older workers and (c) women in the workplace; and if he will make a statement. 
John Healey: Climate change levy receipts were£744 million in 2005-06. It is not possible to break this figure down between the public and private sectors because HMRC collects the levy from energy suppliers as opposed to individual businesses and public sector organisations.
However, estimates set out in the Cambridge Econometrics report: Modelling the Initial Effectsof the Climate Change Levy, available at www.hmrc.gov.uk, suggest that around 20-25 per cent. of climate change levy revenue is from the public sector.
Mr. Laws: To ask the Chancellor of the Exchequer how many compensation payments were made by the tax credits section of his Department in each month from May to October 2006; what the total value of such payments was in each quarter since April 2003; and if he will make a statement. 
Mr. Timms: The circumstances in which HM Revenue and Customs will make compensation payments to its customers are explained in the Department's Code of Practice 1 Putting things right which is available atwww.hmrc.gov.uk. The Department will pay compensation for reasonable costs incurred as a direct result of its mistakes or delays and to recognise worry and distress caused by those mistakes and delays. It does not keep separate details of compensation payments made specifically due to maladministration or poor service.
For the number and value of compensation payments made up to 30 September 2006, I refer the hon. Member to the answer my right. hon. Friend the Paymaster General gave him on 26 October 2006, Official Report, columns 2027-28.
In line with the Government's response to the Gowers report we will be informing the Commission of those recommendations which fall within the Commission's area of competence. With respect to the Directive on Copyright and the Information Society 2001/29 this includes provisions for the use of orphan works and the creation of derivative works.
Mr. David Anderson: To ask the Chancellor of the Exchequer what assessment he has made of the potential impact on UK finances of proposals to reduce the rate of corporation tax in Northern Ireland; and if he will make a statement. 
Many companies trade in different regions of the UK. It would not be easy to determine the proportion of their profits liable at a devolved rate. In addition, such a measure could also create opportunities for some companies to manipulate the rules in order to
benefit from the lower rate. This may well result in a system that would place a significant administrative burden on both businesses and the Government.
Mr. David Anderson: To ask the Chancellor of the Exchequer what representations he has received from (a) trade union and (b) business interests in Northern Ireland on proposals to reduce the rate of corporation tax in Northern Ireland; and if he will make a statement. 
John Healey: The Council for Science and Technology report Technology Matters was published in February 2000. The work was led by Professor Sir Alec Broers. The other members of the group were Professor Kumar Bhattacharyya, Dr. Chris Evans, Sir Robin Nicholson, Dr. David Potter, Miss Emma Rothschild and Mr. J Martin Taylor, assisted by Professor Alan Hughes, Director of the ESRC Centre for Business Research, university of Cambridge.

104 items of archaeological material from Southern Asia;
6 religious statues from India;
2 religious statues from Cambodia; and
1 early 19th century necklace from the United Kingdom.
Mr. Hoban: To ask the Chancellor of the Exchequer which conferences with fewer than 100 attendees have been funded in whole or part by his Department in the last 12 months; and what the cost to his Department was of each conference. 
Mr. Hayes: To ask the Chancellor of the Exchequer if he will provide the ranking covering financial management and delivery planning referred to in the first indent of box 7C of the Department for International Development's annual report page 200, for each Government Department. 
Ed Balls: The Treasury commends DFID for the progress it has made in improving financial management and delivery planning. However the Treasury has not drawn up any rankings for Departments in these areas.
Dr. Cable: To ask the Chancellor of the Exchequer how many staff were employed through employment agencies in (a) his Department and (b) each of its agencies in each of the last five years for which information is available; and what the (i) average and (ii) longest time was for which these temporary workers were employed in each year.
