My petition on the Prime Minister's website - new measure of progress needed

I was really pleased yesterday to receive the email below from 10 Downing Street.

I urge anyone who reads this blog to click the link below and sign my petition (it will be there to gather signatures for the next 12 months or so). If you can pass on my petition details to others that might also sign, this would be great!

Your petition has been approved by the Number 10 web team, and
is now available on the Number 10 website at the following
address:

Your petition reads:

We the undersigned petition the Prime Minister to replace
GDP/GNP as the key indicator of progress in society with a
measure, such as the Index of Sustainable Economic Welfare, or
similar, to help take us in a much greener direction.

Continued use of GDP/GNP (economic growth) as the major
indicator of progress in our society is seriously flawed.
Accounts which produce GDP/GNP do not subtract the costs of
producing economic growth such as climate change and resource
depletion, and so are most unlike normal balance sheet
accounts. Any greener government would use a much broader and
more balanced indicator of progress or wellbeing, such as the
Index of Sustainable Economic Welfare or similar.

Thanks for submitting your petition.
