How much is one ton of CO2?

During the UN framework convention on climate change (UNFCC ) in Copenhagen, these CO2 cubes were set up to show what the actual scale of 1 metric tonne of carbon dioxide. The cubes measured at 27ft x 27ft x 27ft and were created out of shipping containers by artist Alfio Bonanno & architect Christophe Cornubert of PUSH. The exhibit was "designed to transform peoples' perception of climate change."Photos from Designboom's blog(credit: Designboom)
