Big sign, even bigger message

Sign is nearly five metres wide
 and almost 2.5 metres high.

The illuminated sign on Shepparton’s busiest intersection that lists CO2 levels is actually 4.8 metres wide and 2.4 metres high.

Shepparton’s Top Gun Multimedia CEO, Kelly McPherson, has corrected an earlier report (thanks Kelly) suggesting the sign was somewhat smaller than that.

The sign is supported by Shepparton’s GV Crop Protection in Drummond Rd, the carbon dioxide information is sourced through services provided by the CSIRO and the Bureau of Meteorology and the design was by Top Gun.

Taking advice from Professor David Karoly at the University of Melbourne’s School of Earth Sciences, the figures shown on the sign are base-line data taken at the Cape Grim air pollution station in north west Tasmania.
