Britain to urge green accounting at Rio+20 summit  LONDON Thu
Feb 9, 2012 11:57am EST  LONDON (Reuters) - Britain will urge
businesses and governments to start accounting for natural
capital as an additional way of measuring economic activity at a
U.N. sustainability summit in June, its environment minister
said on Thursday.  This could mean moving towards a concept of
GDP+, or measuring the use or loss of natural resources like
water, agriculture and forests to gauge economic activity, in
addition to relying solely on economic output.  "A snapshot of
the state of economies based on GDP (gross domestic product) is
too narrow," Caroline Spelman told reporters after a speech to
businesses and non-governmental organizations on the UK's aims
for the Rio+20 summit.  "Green accounting would work for all
countries. We believe you can really drive significant
'greening' if you take proper account of the value of natural
capital in your government accounts," she added.  Currently,
governments compile national accounts
