Porkies and half truths 3

Despite claims that the British Government is leading the rest of the world, if not the universe, in its reduction of greenhouse gases, - a frequently claimed achievement, according to the National Audit Office the true picture is rather different.

It seems that the Government omits British gas emissions from aviation(!), shipping, business operations abroad and holiday-making. The figure is thus kept artificially (dishonestly?) low.

The difference may be seen in the figures quoted by the Government of 656 million tons in 2005, whereas the Audit Office calculates the true figure as 733 million tons. On this basis the Government's claim to have reduced the figure in 1990 by 6.4% is abolished, - the true result is an increase since 1990 of a similar proportion!

If you start using whatever suits you, ignoring anything inconvenient, then statistical comparisons lose their validity completely. The Government does have available the figure on the full basis collected by the Office for National Statistics", but chooses not to use it.

I wonder why?
