2000 Carbon CO2 Ozone 
Green Car Congress

Net warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions. Pitari, M.J. Prather, R.

While reductions in particulate matter tend to produce local health benefits, the scientists found health and agricultural benefits from reduced ozone disperse more widely.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. Of that, international shipping accounts for 83% (870 TgCO 2 yr ?1
