Impact of CO2 on Human Decision-Making Performance

Caption: Overturning decades of conventional wisdom, researchers at Lawrence Berkeley National Laboratory have found that moderately high indoor concentrations of carbon dioxide (CO2) can significantly impair people’s decision-making performance. On nine scales of decision-making performance, test subjects showed significant reductions on six of the scales at CO2 levels of 1,000 parts per million (ppm) and large reductions on seven of the scales at 2,500 ppm.
