UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

A strong absorber of solar radiation, black carbon exhibits significant climate warming properties. On the other hand, the reduction in CO 2 emissions associated with the enhanced fuel economy of GDI vehicles would yield a globally uniform negative radiative effect, estimated to be ?0.013 W/m 2 over urban regions.
