Global climate and human health effects of the gasoline and diesel vehicle fleets

We quantify the impacts of global gasoline and diesel emissions on air quality, climate change and human health, by employing the NCAR CESM CAM5-Chem model at the horizontal resolution of 0.9 degrees latitude by 1.25 degrees longitude as well as integrated exposure response functions in combinations with the most recent 2017 Global Burden of Disease. We run three sets of CAM5-Chem model simulations: (1) the control model simulation with anthropogenic emissions from IIASA GAINS ECLIPSE V5a for the year 2015 (hereafter referred to as CRL2015); (2) one sensitivity simulation identical to the control but with global gasoline emissions off (referred to as GSL2015); (3) one sensitivity simulation identical to the control but with global diesel emissions off (referred to as DS2015). The differences between CRL2015 and GSL2015, and between CRL2015 and DS2015, will be the net impacts of global gasoline and diesel sectors, respectively.
