Installation for the United Nations Climate Change Conference in Copenhagen, Denmark - December 2009.

Measured and stored at standard atmospheric pressure, one tonne of CO2 occupies a cube the size of a three-story building 8.2m x 8.2m x 8.2m (27ft x 27ft x 27ft)! This is the amount of CO2 the average person in an industrialized country emits each month.

Visualize a Tonne of Change is presented by Millennium ART in partnership with the United Nations Department of Public Information, powered by Google and YouTube, and produced by Obscura Digital.
