Everyone seems to be upset about carbon dioxide emissions but are you aware that carbon dioxide is too heavy to reach the atmosphere?  If you remember your science, you will recall that every element has a specific gravity.  The air all around us has a specific gravity of 1.000.  Helium, which is lighter than air, has a specific gravity of 0.138 so obviously is rises into the atmosphere.  Carbon dioxide has a specific gravity of 1.5189 which is too heavy to get off the ground.  Therefore, there should be no regulation of emissions which cannot affect the atmosphere.
