Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. This multi-site experiment clearly establishes streams and rivers as important sources of nitrous oxide.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.
