Dear Secretary of State
I enclose a cutting from the Guardian newspaper of 11 January 2008, relating to an alleged increase in carbon dioxide emissions as a result of increases in traffic levels in cities in the UK.
As I am sure you are aware many people follow such news with interest and concern. However, we do not necessarily believe everything that is published in the papers. Therefore. I would be very grateful if you would let me know whether the facts stated in this news item are correct.
Yours faithfully
