Dear Dr Vickery

I refer to your request for information about aircraft emissions. Your
request was received on 4 April 2009 and, since it relates to
environmental information, I am dealing with it under the terms of the
Environmental Information Regulations 2004 (`the EIRs').

Under Regulation 6 of the EIRS, a public authority is not obliged to make
information available in a particular form or format if the information is
already publicly available and easily accessible to the applicant in
another form or format.

Total carbon dioxide emissions from both domestic and international
aviation are published on the Department's website in `Transport
Statistics Great Britain', table 3.7(a). The table is available at:
[1]http://www.dft.gov.uk/pgr/statistics/dat...

(Please follow the link to TSGB 2008 Chapter 3: Energy and the environment
- data tables.)

The emissions estimates are based on flights departing UK airports for the
years 1970 to 2007. DfT does not hold any data for 2008; this will be
available in February 2010. The estimates are sourced from the National
Atmospheric Emissions Inventory (NAEI) as published by the Department for
Energy & Climate Change (DECC) on 26 March 2009.

Detailed descriptions of the methods and the source data used to produce
the emissions estimates is published in the Annex (section A3.3.5.1 -
Aviation) to the national inventory report submitted by the UK to the
United Nations Framework Convention on Climate Change (UNFCCC), `UK
Greenhouse Gas Inventory, 1990 to 2007 - Annual Report for Submission
under the Framework Convention on Climate Change'. The report is
available at:
[2]http://unfccc.int/national_reports/annex...

(I have attached an electronic copy of the report Annex for your
convenience, section A3.3.5.1 can be found on page 303, which is page 59
of the Word document.)

Total aviation fuel consumption is published in `Transport Statistics
Great Britain', tables 3.1 and 3.2 for the years 1997 to 2007. The tables
are available on the DfT website at:
[3]http://www.dft.gov.uk/pgr/statistics/dat...

(Follow the link to TSGB 2008 Chapter 3: Energy and the environment - data
tables.)

DfT does not hold any data for 2008; this will be available in November
2009. The fuel estimates are sourced from the `Digest of UK Energy
Statistics' (DUKES) as published by the Department for Business,
Enterprise & Regulatory Reform (BERR). A detailed breakdown between fuel
types is available in DUKES - tables 3.2-3.4 provide estimates separately
for both aviation spirit and turbine fuel for the years 1998 to 2007.
Tables 3.2-3.4 of DUKES are available at:

[4]http://www.berr.gov.uk/energy/statistics...

(Follow the link to [5]Petroleum products: Commodity balances (DUKES
3.2-3.4).)

If you do not have access to the Internet at home, you may be able to use
facilities at your local public library, or you can request a print out of
the tables by contacting me.

Under Regulation 11 of the EIRs, an applicant may make representations to
a public authority in relation to a request for environmental information
if it appears to the applicant that the authority has failed to comply
with a requirement of the Regulations in relation to that request. If you
are unhappy with the way the Department has handled your request or with
the decisions made in relation to your request you may complain within 40
working days of the date of this letter by writing to the Department's
Information Rights Unit at:

Your right to complain to DfT and the Information Commissioner

You have the right to complain within two calendar months of the date of
this letter about the way in which your request for information was
handled and/or about the decision not to disclose all or part of the
information requested. In addition a complaint can be made that DfT has
not complied with its FOI publication scheme.

Your complaint will be acknowledged and you will be advised of a target
date by which to expect a response. Initially your complaint will be
re-considered by the official who dealt with your request for information.
If, after careful consideration, that official decides that his/her
decision was correct, your complaint will automatically be referred to a
senior independent official who will conduct a further review. You will be
advised of the outcome of your complaint and if a decision is taken to
disclose information originally withheld this will be done as soon as
possible.

If you are not content with the outcome of the internal review, you have
the right to apply directly to the Information Commissioner for a
decision. The Information Commissioner can be contacted at:
