Study finds that replacement programs that reduce vehicle lifetime can result in increased lifecycle CO2 emissions

Green Car Congress

Empirical results also revealed that even if the fuel economy of less fuel-efficient ordinary passenger vehicles were improved to levels comparable with those of the best available technology, i.e. hybrid passenger cars currently being produced in Japan, total CO 2 emissions would decrease by only 0.2%. —Kagawa et al.

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

Green Car Congress

Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. Widespread adoption of new engine technologies raises concerns about changes in emissions and their effects on air quality and the climate. of the data. Credit: ACS, Saliba et al.
