"This Government is one of the largest greenhouse gas emitters in the state," he said.
"We hope that our determination to reduce our carbon footprint will, in turn, inspire and encourage industries and other governments to follow our lead, thereby increasing demand for green energy.
"In other words, from little things, big things grow.''
Well Mr Rann how about starting by getting rid of the six and eight cylinder motor fleet that shuttle Ministers and other public servants around the state. How about supporting electric cars and other public transport.
Other governments around the world have made similar pledges, but not in Australia.
New Zealand Prime Minister Helen Clark has set a target of taking the whole country carbon neutral.
Mr Rann already runs a carbon-neutral Cabinet, with ministers reducing their carbon footprint and buying credits (at tax payers expense) to offset any remaining emissions.
South Australian MPs have been encouraged to follow suit to create a carbon-neutral Parliament.
All very well, but how about some real action and not empty promises from Captain Smiley Empty Promises and his merry bunch of Carbon Neutral Yes Men.
