Ozone is one of the most dangerous greenhouse gases and is prominent throughout the troposphere. Emissions of chemical species that can lead to the formation of ozone have been lessening in developed nations and growing in developing nations. Using the global chemical transport model CAM-chem changes in ozone concertation in the troposphere were analyzed in relation to different factors and variables. Specifically, the tropospheric ozone load was projected from 2010-2040 and emissions in different regions were manipulated in order to see the global effect. It is important to make the distinction between regional increases in anthropogenic ozone emissions and simple increases in magnitude. It is predicted that increases in ozone emissions in certain regions will have a greater impact on the total global ozone load. Specifically the results of previous studies which determined a greater significance to South and East Asian emissions shall be replicated with the projection into the next thirty years
