The UNEP calculated its dollar amount of savings from a 2010 study executed by scientists working at California State University, in Northridge. Primary factors in the study included lower medical costs, the pros of a healthier global economy, and a drop in criminal activity. Believe it or not, exposure to leaded fuel was correlated with higher crime rates. While the eradication of leaded fuel is a major landmark achievement for every nation on Earth, the agency also warned that fossil fuel use must still be substantially reduced if we can venture to hope for a brighter future than the one suggested in recent and forthcoming climate change disasters.
